Things to Consider

I called up a local pressure washing service provider for the very first time and they showed up with a pressure washer mobile trailer.   So I caught the bug, decided to get my own pressure washer for me since it’s such a useful piece of equipment and has become increasingly reasonable in price.

Yes, it’s pressure washer that can help to solve your problem. But, you don’t know about the device. First, you should know some vital features and how they work. Let’s look at the procedure of how to wash a house effectively.

1. Nozzle

The nozzle is one of the most important features of a pressure washer. It’s also a spray tip. Let me tell you an example, you want to reach the window which is 10 feet far from you. But it’s not possible for you to reach there.

Now, what can you do? Use the nozzle to solve the problem. Always use the 25 or 40-degree nozzle tip for better performance. Controlling the flow and velocity is the main job of the nozzle.

2. Detergent

What do you think? Can the water only remove the dirt from your house siding? No, the detergent makes the cleaning process more comfortable.  Detergent can make your building smooth and shiny. The house siding may risk damaged without using the detergent.

There are different kinds of detergent in the market. Choose solutions that are environmentally friendly.  For more info here’s our guide on the best vinyl siding cleaner.

3. Brush attachment

A brush isn’t essential while pressure washing your house siding. Moreover, you can use the brush attachment for better cleaning capacity. It can also give a better performance of the power pressure. The brush will scrub and push the dirt and grime.

There are different kinds of brush. The brush can clean the dirt off vehicles, decks and other surfaces. They are comfortable to use. Choose a brush of less than $40.

4. Extension Wand of the pressure washer

Owner of a two-storied building or more? The extension wand is suitable for you. It can help your power washing easy. It has extra attachments to put on the end of the extension wand to reach the highest area.

The process is possible to safely stand on the ground. You can remove the dirt of second storied surfaces. It can also clean the gutters from the ground. Telescoping extension wand is our first choice for you.

5. GPM and PSI of a pressure washer

Let me explain about the GPM and PSI. GPM stands for gallons per minute. It means the amount of water flow that comes from the pressure washer. And the PSI stands for pounds per square Inch. It refers to the amount of cleaning pressure that the pressure washer can produce.

You can select the machine with the GPM of 2.3 and PSI of 2600 for better performance. Try to find a higher GPM pressure washer. Because the high GPM can clean the large surface.

I have written a full article on water consumption by a pressure washer. Do check that out!

Everybody wants to be safe while he is in working. We find some simple things that are an injury. Follow our instructions and save from the harm and damage.

1. Electricity and Water

Electricity is a crucial and sensitive thing in our everyday life. You should always care about it. While starting pressure washer, make sure that you turn off the power of the outdoor electrical ports except for the machine. It may occur great damage if you switch on the electricity in your home.

Water gets into the electric port and damage all. Do you have confidence enough in your power lines? You should always be aware of your lines. Some lines of the houses throw the ground and some run with their roof.

Which one is yours? Recheck the line and make sure that you do not fault in the power line. If you see any error, repair it as soon as possible. Then go for your next action. Remember, This is a vital part of power washing home exterior.

2. Risks of Ladders

Many people use the ladder while washing their house. They don’t know the demerits of the ladder. So, when they want to clean their two-story building, they must think about it. Do want to take any risk during your job? Ok, I get the answer.

Using the machine it has some risk. Using a ladder is one of the dangers. We tell you not to use the ladder. You can use the risk-free extension wand and better performance.

3. Safety equipment

Yes, you should wear some safety equipment. These are called PPE, PPE stands for personal protective equipment. You can save your eye first. So, you should wear proper safety goggle to prevent flying objects.

It’s better if you wear the proper gumboots while working with the pressure washer. Never start pressure washing a house without wearing the boot. The gumboot can help for better work.

Hands are the most common injury-prone body part during pressure wash. So, use gloves when you are ready for washing. The gloves protect the hands from injury and improve the grips. If you use the gas-powered pressure washer, it’s essential to use the ear protection.

Ear protection can protect your hearing. It’s not necessary if you’re using the electric pressure washer.

4. Detergent and Soap

Soap is a detergent that is made of oils and fats from animal and plants. Bar soap utilizes sodium as salt. Liquid soaps typically employ potassium as salt.

The soap can break down when mix with the water. When you start to clean with the soap, it also dissolves the dirt and grime. But, the detergent made from chemicals. Detergent is suitable for washing clothes.

– Connect the siphon tube to the weighted filter.

– Place a container near to the machine.

– Fill the container with the solution. Drop the weighted filter into the container.

3 Best Karcher Pressure Washer Reviews That You Can Depend On 100%

Who loves pouring money down the drain?

I bet you don’t.

karcher pressure washer reviews

That’s why you need to know about any pressure washer before you spend your hard earned money to buy one.

Having said that, it’s not a realistic task by any means to buy each pressure washer one by one and test it for yourself.

Particularly when you will find several good brands manufacturing pressure washers maintaining the quality, it is very easy to get overwhelmed with information.

To make your life easy, I decided to write this best Karcher pressure washer reviews guide.

Here I am going to point out the upside and downside of two of their electric pressure washers and one gas pressure washer.

Needless to say, I will also give you a brief introduction to the Karcher as a brand and discuss why Karcher is considered as one of the pioneers in the power washing industry.

So, let’s get to the business.

Karcher Pressure Washer Reviews 2019 [In Depth]

Here’s a great in-depth discussion of Karcher branded pressure washers.

1.Karcher K5 ( 2000 PSI, 1.4 GPM ) Electric Pressure Washer Review




  • Comes with everything you need for assembling.
  • Easy to assemble.
  • Powerful and easy to use.
  • Optimum water consumption.
  • Lightweight
  • Larger wheels make the mobility easier as you would have expected.
  • Doesn’t make any noise during the operation.
  • Leak-proof construction.
  • Improved base to help prevent tipping.
  • Reasonably priced. Worth buying this one than renting any other pressure washer.
  • The hose and cord can easily be carried and stored.
  • Dedicated storage for trigger gun.
  • A handy detergent dial to regulate the amount of detergent use.
  • The water-cooled induction motor ensures high performance and longer lifespan.


  • Not a perfect pressure washer for commercial use.
  • A bit longer wand could have helped taller people to operate at the ground level. But you can always use an extension.
  • Assembly instruction could have been a bit clearer. But that’s not a big deal as assembling this washer is a cakewalk I believe.
  • Brass hose attachment would have been a better option than plastic considering the durability.

Key Features

  • High-Pressure hose – 25ft
  • Electric Cord – 35ft

Getting the induction motor in this price range is a great bonus I must say.

Here is what any Karcher pressure washer beats its competitors. They offer their products in a reasonable price range without cutting the corners.

This particular K5 electric pressure washer has got 2800 cleaning unit.

If you are not sure what the cleaning unit aka CU is.

It is the multiplication of PSI and GPM. So in this case 2000 x 1.4 = 2800

CU gives you a more clear picture of the pressure washer’s capability than the PSI or GPM alone.

As the CU of this K5 model has got 2800, I must say this is a pretty good score. The performance of this unit reflects that as well.

Karcher K5 offers you some advanced technologies to make your life easier while you clean some stubborn dirt. I found these features really helpful during the cleaning process.

For example, it comes with two wands. One is the dirt blaster wand and the other one is the Vario power spray wand.  Multiple wands is super handy.  Some home owners even spring for the 24 ft telescoping pressure washer wand.

I found the dirt blaster wand delivers deadly pressure to remove stubborn stains whereas the Vario power spray wand plays a handy role for less-intense cleaning.

The Vario power spray also allows you to control the pressure on the wand.

How cool is that?

Having said that, remember this is not a perfect pressure washer for commercial use.

Despite having some downsides, I still believe this Karcher K5 premium electric power washer is the beauty and the beast for you.


Particularly if you are looking for some pressure washer for home usage, or detailing large vehicles, cars, stone walls, etc.

2. Karcher K2 Plus ( 1600 PSI, 1.25 GPM ) Electric Pressure Washer Review




  • Compact
  • Easy to set up and use.
  • A handy and powerful pressure washer for home usage including detailing your car.
  • Reasonable price.
  • Lightweight and easy to store.
  • Perfect height unit with strong fixed handle.
  • Easy to maneuver.
  • Having two wands is a plus for anyone using a pressure washer. This unit comes with two wands.
  • Improved dirt blaster.
  • Trigger gun holder for easy storage when not in use.


  • This K2 Plus comes with a universal motor and typically a universal motor is noisier than an induction motor. No wonder this unit is a bit noisy, but don’t worry. It is not loud.
  • Not a perfect one for heavy jobs.
  • Seems a tad flimsy fitting to me and components are mostly plastic made.

Key Features

  • High-Pressure hose – 20ft.
  • Electric Cord – 35ft

This very Karcher power washer is suitable for removing normal dirt from your car, garden tools, bicycle, furniture, etc.

Don’t expect any real impressive cleaning performance if you are up to tough grime.

The cleaning unit (CU) of this unit is 1600 x 1.2 = 1920.

So clearly this is not a perfect one for removing tough dirt but pretty capable of clearing normal dirt.

Like the previous model that I reviewed, this one also comes with two wands ( dirt blaster and vario power spray ). These two wands make the controlling of the whole cleaning work a cakewalk.

The spray gun could have been better in terms of quality. But you can’t expect too many things in this price range.


Overall, this is a lightweight yet powerful unit for cleaning home kits and cars.

3. Karcher G2900X ( 2900 PSI, 2.4 GPM ) Gas Pressure Washer Review




  • This gas pressure washer comes with a large removable detergent tank. That will surely make your life easier during the cleaning process.
  • The larger and quality wheels make this super maneuverable.
  • The high-quality handle of this unit helps to move it with ease, and you can fold that handle down for compact storage.
  • Trigger gun holder helps to keep the gun securely when not in use.
  • Easy to assemble.
  • Sturdy and durable.
  • An incredibly powerful unit.
  • Excels in performing tough jobs.
  • The commercial-grade trigger gun works flawlessly.


  • Although the assembling is fairly easy but a clearer assembly instruction manual would have made your life easier than ever.

Key Features

  • Nozzles included – 15°, 25°, 40°, Soap
  • Engine – Karcher KPS 196

Unlike the previous Karcher pressure washer, this one is a gas powered pressure washer.

Don’t expect this one will remain quiet like the electric power washers. But I must say, this does not whine either.

The cleaning unit is 2900 x 2.4 = 6960.

Needless to say, this is an incredibly powerful unit that will clean the toughest dirt in no time.

You will get four pro-style nozzles with the package.

As this is a gas pressure washer so you can take it to anywhere you want without worrying about the electric cable length and electric sources.

Starting this unit and making it run is not any hassle either.

All in all, this is easy to move and operate gas pressure washer from Karcher that can surprise you with its immense power of pressure washing.

Buckle your seatbelt because now I am moving to the next part.

Now I am going to introduce you to the Karcher brand.

About Karcher Company

I can write pages after pages about Karcher if I want to go for every detail of the company.

That’s right!karcher pressure washer company logo

But that will be too much of a good thing, no?

That’s why let me cut to the chase with the key factors of this old brand.

So, it will help you to understand how good and professional this company is in terms of manufacturing pressure washers and providing after-sales service to its buyers.

Karcher as a brand came into existence in 1935.

A young engineer Alfred Kärcher founded this company in Germany. Back then the aircraft industry in Germany started using his petrol-driven hot air blower and caterpillar tube to heat the aircraft engines in winter.

In 1939 Kärcher took over a chemical and pharmaceutical plants to established his factory Winnenden, Germany. It is still the worldwide headquarter of Karcher and the manufacturing hub.

1950 is the year when Europe saw the first hot water high-pressure cleaner, and no wonder it was invented by Alfred Kärcher. So, the journey of the Karcher pressure cleaner begins here.

After releasing several revised and improved version finally they released the DS 59 pressure washer and became the industry boss in 1958.

Ok, I know what you’re thinking.

When did Karcher enter America, right?

In 1982 this brand entered America and needless to say, they are now one of the leading companies in the cleaning industry.

They introduced the first portable high-pressure cleaner for household usage in around 1983.

Now they are operating in 67 countries having over 12000 employees and over 3000 products.

They are not only selling products but also providing different services related to pressure washers, home, and garden service.

Karcher manufactures both gas and electric pressure washers. Not to mention, they also make diesel powered pressure washers for heavy jobs.

They know how this industry works. They know how to provide customer support. I believe you will not regret buying their products.

Why should you buy Karcher pressure washer and why is it better than others?


If you read the history of Karcher that I’ve written above, you can easily understand that Karcher is not any company who came out of nowhere in recent past.

Karcher as a brand has got a long past that shows they are one of the pioneers in the pressure washer industry in Europe.

Once they entered America, they acquired the American market as well with their innovative designs and state of the art technology and quality.

The quality and usability of their pressure washers have been admired by their users from the very beginning of their journey.

Still not convinced?

Let me present some more facts that may prove the quality of the products that this brand can produce.

To showcase the level job that Karcher pressure washer can do, they cleaned some of the most iconic structures.

They cleaned structures and buildings like Statue of Liberty, Mount Rushmore, Seattle Space Needle, and some more structures in different parts of the world.

The only reason behind they did is to showcase their pressure washer’s ability to clean any kind of dirt and grime.

Of course, their pressure washers of different cleaning capacity withstand to their respective tasks.

They consider and give priority to their user feedback.

With the mixture of the customer feedback and engineer’s innovative ideas, research, and development they are improving their pressure washers in every release.

So, I must say they’ve established a nice ecosystem to grow their brand.

Let’s compare Karcher with some of its main competitors in the market.

If you have a look at the company like Sun Joe, AR Blue Clean, Ryobi, Greenworks, Generac, Simpson, and Dewalt, all of them are making quality products in different prices ranges.

To me, what makes Karcher different from them is the quality and service you get in the long run against the money you spend. They have their own product like Karcher pump guard for winterizing pressure washer.

Yes, true.

Karcher offers you high-quality products within reasonable price with great customer service. Of course without sacrificing the quality of the product.

Moreover, Karcher covers all type of pressure washers and several pressure washer accessories implementing the latest technologies and features.

So I believe the ability to manufacturing a complete package is something that keeps them ahead of their competitors without any doubt.

What the Heck are K2, K3, K4, K5, K7 ???

Karcher has been releasing different electric pressure washers under different model and series name.

They are varying in different parameters like the size, quality of the material, pressure, water flow, etc.

Karcher Pressure Washer Attachments

Different Karcher pressure washers come with some useful accessories. You can buy them separately as well.

Let me give you an idea on some of the most used and handiest pressure washer attachments from Karcher.

Rotating Wash Brush



The three most popular rotating wash brushes from Karcher are WB 100, WB 120 and WB 120 car & bike.

All these three brushes are compatible with almost each of K series electric power washers and few gas pressure washers as well.

These are quality attachments that will help you for thorough cleaning of different surfaces.

You can apply detergents if required. The WB120 model is compatible with garden hose adapter as well. So you can use it without a pressure washer.

WB120 is particularly made to clean your car and bike.

Power Brush

The only power brush that I found from Karcher is the WB150 power brush.

 A handy brush to clean small and hard to reach areas.

This helps you save a significant amount of time, energy, and water.

You don’t have to worry about the sensitive surfaces as well. Because this power brush has got a soft brush head that won’t make any scratch.

So, this is a perfect solution for cleaning garden furniture, garden toys, glass surface, vehicle, car, motorbike cleaning.

Needless to say, the WB150 power brush is compatible with all the electric power washer series of Karcher.

Karcher Surface Cleaner

Karcher offers some high-quality surface cleaners you will surely fall in love with them.



T550, T450, T350 are the three surface cleaners that they are offering currently.

All of them are ideal for large area cleaning, credit goes to the two flat jet nozzles.

T450 and T550 have got integrated additional nozzles as well. You can easily switch from normal nozzles to the power nozzle using the foot switch.

So, these surface cleaners can be a really useful solution for cleaning driveways, patios, garage doors, walls, corner and edges in outside areas, etc.

5 Pressure Washer Detergents and 7 Things to Consider Before Buying [Bonus: Homemade Detergent]

Years ago, when I had my first pressure washer and I was in a ‘get er done’ mood I used some laundry detergent on one of my cleaning projects.

pressure washer detergent and chemical guide

Which was a mistake….your concrete driveway and your underwear don’t (or at least shouldn’t:) have much in common.   There are delicate wash jobs and aggressive wash jobs and it only makes sense that they each require different chemicals.  This of course isn’t a zero sum game.  Just as you can wash your hair with bar soap, you will get better results with shampoo.

So it’s best to use a pressure washer detergent, and you’ll get good mileage out of a bottle, depending on the size of your project.  See some top picks reviewed below.

Now another big factor, is water temperature.  Just like washing greasy dishes, hot water helps. They do make hot water pressure washers but for most of us that’s not a choice.  Doesn’t mean we don’t have other options, even with a standard pressure washer.  

The popular Sunjoe SPX3000  has a max water inlet temp of 104 degrees Fahrenheit (typical max temp of a home hot water heater is 120 degrees Fahrenheit). So you could run some warm water through your pressure washer, but that would be complicated and no reason to push the max temperature specs of our machine.

Better is to have a bucket of hot water and the same detergent handy as we are working.  Let the pressure washer do the majority of the work, and then scrub by hand any problems areas with the hot water mixture.  Or even easier do a hot water pre-wash (ie: dump a bucket of hotwater on the driveway) to loosen things up.

There are not many pressure washer soaps, detergent available in the market so it is recommended to use concentrated detergent for the best result. Or you can also think about preparing something homemade.

Pressure Washer Detergents: TOP 5 Selections

1. Karcher Concentrated Vehicle Detergent

Ultimate 7 tips for final detergent selection

The difference between pressure washer soap and pressure washer detergent

  • Soaps and detergents are very similar in chemical properties still they a major difference. Soaps are formed by natural products like starting with fats and oils which are obtained from plants or animals. These are combined with high-pressure steam while producing fatty acid and glycerin. Combining the fatty acid with salt produces soap.
  • Sodium soaps are converted into bar soaps and potassium salt is used for liquid soap.
  • Soap breaks down when mixed with water or oil due to its hydrophilic and hydrophobic ends
  • Detergents are produced from man-made chemicals
  • Soaps are used for skins and detergents are used for clothes

When to use soap and when to use power washer detergent?

Soaps are biodegradable and do not possess a threat to the environment. But soap mixes with sodium and magnesium in hard water to create an insoluble mud type residue. This white residue can stick to your surface.

On the other hand, the detergent does not have this problem.  The special benefit of detergent is that it is engineered for different cleaning surfaces.

The most effective solution is to combine the soap and detergent together.

How does a pressure washer detergent, nozzle and injector work?

This is a very interesting process! The proper blending of soap or detergent with the power washer water flow is very important. This introduction of detergent can be done in two ways. Before entering the pump (upstream) or after leaving the pump (Downstream).

Downstream pumping systems provide multiple options. This downstream injection system is equipped with a nozzle with a variable pressure adjustment capacity. A venturi injector is used for making a pressure differential which will draw the pressure washer detergent from the container into the system.

In the upstream delivery system, a float system is necessary to produce zero pressure which delivers the chemical into the system. So the downstream system allows more option for chemical delivery.

Is pressure washer soap, detergent or other chemical solution safe for your environment?

Pressure washer detergent and other chemical solutions must be environment-friendly as the chemicals mix with the ground which will mix with rainwater underground. So be sure to check the label if it is biodegradable.

Cleaning is good but you need to take off your environment too!

Difference between Residential and Industrial pressure washer soap, detergent and other chemical solutions and which one to use?

The math is simple. Industrial things like pressure washer car soap come in large barrels. Industrial pressure washer detergent is supplied in concentrated condition. And the residential grade comes in pre-mixed condition.

If you pressure wash around your home a few times a month then you should go for the residential pressure wash soap or chemicals. Buying a residential pressure washer detergent like vinyl siding cleaner will cost you some extra bucks per gallon. At least you do not have to worry about diluting the concentrated chemicals.

And finally, if you pressure wash for living the industrial range is for you. Why? It comes in a large barrel and concentrated. Just use when you need it. This will save you some money.

What kind of soap to use in pressure washer [Foam or no foam?]

If you love to play with foam then choose carefully. Let’s discuss here. First, read the label on the pressure washer detergent bottle. Some of them can cause little foam. If you want less foam its good! On the other hand, if you want more foam then using foam cannon might be a good idea.

Using a foam fun party to wash your car is a great idea!

Your detergent might not be able to provide you with a foam fiesta you are looking for. You know what? I love the view of a car covered with foam.

There are some pressure washer soaps available on the market. A foam cannon combining with a pressure washer is a great combination.

You may consider my opinion. Less foam for your driveway and more foam for your cars!

Prepare Homemade Pressure Washer Detergent

Thinking about an eco-friendly pressure washer detergent is excellent. Although, you may not get the same result as you will get with a chemical detergent, yet let’s try this.

This requires some crazy simple ingredient for preparing a homemade detergent that works. Mix 2/3 cup of household cleanser powdered with 1/3 cup of phosphate-free laundry soap. Mix these with a gallon of water.

The mixing has to be proper for a good result. Pour this solution in the pressure washer detergent tank and start cleaning.

You may have to use this process more than once to get a good result. Mildew buildup can be a challenge for this detergent to overcome. To get over this you can use vinegar on mildew.

This is helpful for plants, keeping them away from chemical detergents.

Before I Let You Go

Using some good detergent with a pressure washer is a solid way of getting a good result.

And you can also try making something of your own at home. This might not be as powerful as the chemical ones.

I suggest not to use hot water unless you have an industrial pressure washer. Pressure washer detergent or soap is excellent for removing grimes.

how to adjust foam cannon soap ratio

How To Adjust Foam Cannon in 10 Minutes [Soap Ratio+PSI+GPM]

The primary reason behind writing this article is eliminating the confusion on “how to adjust foam cannons” by sharing my real-life experience.

how to adjust foam cannon soap ratio

There are two types of foam cannon users.

One that posts epic foamy car wash videos on Youtube and the other comments on the video “how to make foam cannon more foamy?” People asking these are seeing just soapy water with their foam cannon.

That’s frustrating. I know that.

Just stay with me for two minutes reading this article. I am going to share what mistakes you are making and how to fix them.

Also, I’ll share the adjustment procedure of cannon and the perfect foam cannon soap ratio.

Do you want to wait? No? Let’s jump in.

(I’m assuming you already have a foam cannon here, but if not we also cover choosing the best foam cannon for pressure washer here.

How To Adjust Foam Cannon

I think it’s better to follow the backward process for learning a process. Let me show you the mistakes you might be making with your foam cannon.

Avoid these mistakes and do the correct things mentioned.

1. Are You Using The Wrong Pressure Washer?

Foam cannon is directly dependent on PSI and GPM.

No matter the pressure washer is electric or gas-powered, a foam cannon requires a minimum PSI and GPM. Fortunately, you can find the requirement of specific PSI and GPM on the instruction manual of foam cannon. In addition, you can also find that information in the product description section if you buy online.

PSI and GPM are the two factors responsible for sucking up the soap and mix it with the water. Furthermore, these factors also produce a suitable soap mixture for foam.

For example, if you own a foam cannon that requires 1.1 GPM water surely it won’t work properly with a 1.0 GPM water supply.

As a result, you are kind of forced to select a pressure washer that meets the foam cannon requirement. However, selecting a pressure washer depending on the foam cannon is hilarious. Having said that, I got some pressure washers for cars reviewed in this article.

You better buy a pressure washer of minimum 2000 psi and 1.4 GPM for foam cannon usability and think no further.

2. Are You Using The Proper Soap?

Once I saw someone using washing machine detergent in foam cannon. Turned out crappy!

Don’t be stupid like that guy!

Car soaps are good for foam cannon. But even a good car soap can sometimes be tricky for more sud. And less sud means low foam.

To focus on foam, some manufacturers produce specialized foam cannon soap. Surely, these soaps are king of sud. More sud means more foam.

Personally, I like the concentrated soaps as they give you full control of mixture. Specialized soap for foam cannon will mix with water properly and later produce thicker foam.

I have written a whole article on car wash soap.

3. Foam Cannon Soap Ratio

Using the wrong soap ratio can be another good reason for watery foam.

However, the perfect soap ratio does not exist. The ratio can differ regarding the soap brand, the bottle size, and water quality. Furthermore, once again your soap ratio need to match with your pressure washer’s GPM and PSI.

Clearly the ratio depends on trial and error method. As you can see, the ratio is dependent on several things which can only be achieved by trial and error method.

Regardless of the different variables, there is some kind of universal ratio that I am going to share with you.

I personally use 2 ounces of soap with 10 ounces of water.

However, experts suggest using 1 ounce of soap with 10 ounces of water. Filling a bottle with water where you have 1 ounce of water is not a good idea. This way the mixture will be very much soap less.

On the sweet spot, use 1 ounce of soap wit 10 ounces of water.

Here’s a video on soap mixing hack:

 4.  Wrong Orifice Size

Another tiny but crucial point you might be missing out is the orifice size, which is a tiny hole on the nozzle screw set.

There are usually two sizes of orifice available. 1.1 mm and 1.25 mm (hole size).

1.1 mm orifice requires a minimum of 1.4 GPM and 1100 PSI of water pressure.

1.25 mm orifice requires a minimum of 1.8 GPM and 1100 PSI of water pressure.

foam cannon orifice size

In the USA, as the electricity is 110v, the electric pressure washers are of quite a low capacity. To be compatible with it, you need to use a 1.1mm orifice size.

On the other hand, if you own a powerful pressure washer you might want to opt for a 1.25mm orifice size.

Having a bigger orifice size with a low PSI and PGM pressure washer is only going to result in watery foam.

You can easily change the orifice available online. Also, you can play with the adjustment knob.

5. Is the Orifice Dirty?

Not only the orifice size matters but also a clean orifice too.

A dirty orifice can only result in a blocked or inconsistent supply of foam. This can also hamper the suction of soap mixture from the bottle.

If you are thinking about how an orifice can get dirty, then, think about your basin sink. Kind of like that.

Soap residue can create a thick layer around the orifice hole and cause a blockage. Moreover, dust can also be a hindrance here.

No matter how limited your use is, it is recommended to clean the orifice once a month.

Here’s a video on taking care of your foam cannon:

6. Quality Of The Foam Cannon

No matter how hard you try to be precise with the foam cannon soap ratio or PSI or GPM, quality of the soap; a quality foam cannon is always going to be on your side.

A $15 foam cannon will never be the same as the $90 foam cannon.

But, I am not asking you to buy the $90 cannon nor the $15 one. However, you get what you pay for is absolutely true.

As far as I know, chemical guys are the best in these products. Check their foam cannon on Amazon.

As long as you have the right orifice or soap, I assume a $15 is not going to be a problem for you.

Final Thought

As discussed, if you can match any of the above issues with your foam cannon, that’s what you are doing wrong. Please read carefully about these and do it perfectly.

No doubt, a foam cannon with proper performance will give you the best car cleaning experience. Just get your gear and make the proper mixture

Best Foam Cannons For Pressure Washers in 2021 [Top 7 Products For Thicker Foam]

This is simple.

Foam cannons leaves a thick foam mixture which won’t run off easily, so you do not need to dip sponges constantly into a bucket of soap.

That’s why a foam cannon is an insanely awesome invention for car cleaning. And you just got a healthy reason for getting the best foam cannon for your pressure washer.

Best foam cannon for pressure washer

However, creating thick creamy foam with foam cannon is not as easy as shaking the shaving cream bottle and having a fluffy foam.

All right, let’s get straight to the point.

Here’s a Quick Pick, if You are in a Hurry!

Table could not be displayed.

Why Use A Foam Cannon?

I agree with you, a pressure washer with water or a bucket full of soapy water is going to do the washing.

Yet, there is a high possibility of some dirt and mud leftover on the paint, which can cause a scratch in the process of using a wash pad.

Pressure washing your car with plain water gets your car pretty clean in the first place. Using a foam cannon right after it allows the foam to settle down with the dirt or mud on the surface.

To be specific, this process lets the foam soak up the dirt and grime a lot longer, ensuring extreme cleaning of your car. On top of that, using a foam cannon instead of a foam gun is way better with a pressure washer. I’ll get to that later.

In addition, the foam can remove the stuff that you can’t even see which may be missed by the pressure washer. A pressure washer can remove most of the dirt but not all of it.

To cap it off, foam cannon makes lots of foam that grasp all the dirt in it without leaving any detergent soak mark. And, really this looks cool!

On this day, there are tons of models with different advantages to make you confused. In this article, I listed out only some great foam cannon reviews.

Listing the very best ones was not easy, but I did. Let’s jump right in!

Best Foam Cannon For Pressure Washer in 2018

1. DUSICHIN SFL-001 Foam Cannon: Best Cheap Foam Cannon


Since its inception in 2015, Dusichin has been manufacturing quality car wash accessories, based in China.

To continue with that, DUSICHIN SFL-001 grabs the crown of this foam cannon top pick. This one is manufactured by Smartpainter.

Key Points at a Glance:

  • Brass connectors
  • Adjustable mixing knob
  • Durable according to the budget
  • Opaque bottle for the visual level of soap
  • Min PSI 1100

I have always considered a foam cannon under budget yet good promise. This one just complies with this point.  A good foam party in a budget like no other.

The recommendation was made super easy with the two major feature it offers. First of all, the connectors are made of brass, which ensures a tighter connection with your pressure washer. That is how it helps you to save all the water pressure.

Secondly, you get a 33-ounce bottle to contain your car wash soap mixture. That is going to be enough for washing a couple of cars several times before next refill.

On top of it, there is a mixture knob to ensure proper mixture of car wash soap and water. The mixture is so accurate by this process, which later converts into a thick layer of foam with pressure washer spray.


The product is well built for professional category use. However, there are few concerns about the longevity of this bottle or whole setup around the neck. I agree there are some actual complains about the bottle breaking, but I did not get any problem like that.

This is the best one with this budget range.

2. MATCC Adjustable Foam Cannon: Best To Buy 

This MATCC foam cannon is another reason to brag about the cheap product over the pricey branded ones.

You will not regret the performance it delivers with this price tag.


Key Points at a Glance:

  • Brass material
  • Adjustable spray nozzle with a spray pattern controller
  • Minimum 2.0 GPM to maximum 5.3 GPM of water flow
  • Minimum 1000 PSI to maximum 3000 PSI pressure washer
  • Maximum 60°C water temperature
  • 1 Liter bottle capacity

Using less detergent in the bottle works just fine with the pressure washer. Which means, you save a good amount of soap at the end of the month.

This foam cannon is quite familiar with the model I discussed above. The foam lance and main body are made of solid brass and quite heavy. That means no rust, durable great connection.

Other things are quite similar to the earlier DUSICHIN model. Adjustable spray nozzle and bigger bottle for more soap are two of those similarities.

The long tube at the end adjusts the width of the foam spray coverage. You can choose how pointy or wide you want the foam coverage to be. However, wide coverage clears up the bottle quickly.

This adjustability in the foam lance core makes it flexible to perform some additional jobs around your home. Like motorcycle washing, driveways, roofs, sidings and so on. This is built for professional use too.


Rotating the top knob to clockwise direction allows more detergent to mix with pressurized water spray. This will result in thicker foam. The duck-bill paddles inside the nozzle determine the pattern of spray.

Having this one is also a wise option.

3. TriNova Foam Cannon and Gallon Car Wash Soap Kit


Before being acquired by Goldeagle Trinova produces automotive detailing chemicals and after the acquisition, it just got better. They are producing some great automotive detailing chemical and many kinds of protective solutions.

This foam cannon can be nothing but a great one according to the company profile.

Key Points at a Glance:

  • Unique wide neck design
  • Solid premium build quality
  • Top quality brass material
  • Easy to use
  • Minimum PSI 800

This premium category foam cannon introduces a wide neck that prevents it from unexpected breakage. Trinova is a brand of high performance so is this product.

Their Brush connectors are great furnished and come with a premium grade foam nozzle. Even their hinges are unique that feels more premium.

However, I found the bottle is smaller than some of its competitors but enough for two car wash in a row. Increasing or decreasing the amount of foam is just as easy as playing with a stereo sound wheel. This small bottle does not allow more PSI than 3000 and no garden hose is adaptable.


Holding the foam cannon will make you feel a premium product. This is not going to let you down with the performance too, which is premium as promised.

With a premium finish and wide neck, this foam cannon is going to last a longer life than others. That is why this is a good deal for you.

4. Chemical Guys EQP_312 TORQ Professional Foam Cannon


Chemical Guys is the provider of the highest quality car chemical provider and they have this one for you. They are dedicated to car cleaning solution and accessories.

Key Points at a Glance:

  • Air injection technology
  • Comes in a package
  • See through, 32 Ounce bottle
  • Thick foam guaranteed with the proper soap mixture
  • Minimum PSI 800

One thing everyone has to take note off that chemical guys offer this product in a package. So if you go for this package you get a honey dew snow foam cleanser. On top of it, there are other package choices too!

No matter the package is, this TORQ foam cannon is ready to wash your car in every possible way. Their unique air injection system produces some real thick foam.

They claim to have a thread lock system design to protect the bottle head from getting broke against brass. However, I don’t know why there are some complaints about the bottleneck being broken.


With a large see-through soap bottle, you are about to get some good amount of snow foam that has a citrus smell to hypnotize you! However, this bottle is reported to work better with more than 2500 psi pressure washer jet.

All these features with a branded expertise cost a bit more than others. But, you get a premium product that is truly well worth of investment.

5. Fasmov Car Wash Cannon Foam blaster


Honestly, I do not have any idea about the Fasmov brand and its origin. But, this thing does exactly what is supposed to do! Great foam wash, nothing less, nothing more!

Key Points at a Glance:

  • Brass connectors
  • Large 1 liter (32 ounces) bottle
  • Adjustable knob
  • Sturdy cannon for prolonged use

I did not find any kind of brand logo on the bottle (unbelievable), which is a pure white color. To knock it off, this item just covered my car with super quality foam. I just want to say, regardless of the brand, it can dominate over the branded models.

If you do not want to spend extra bucks just for some fancy brand with the same result (no one does), then this is something to have a look at.

The bottle is well built to take a good amount of pressure. Equipped with brass connector just like the top products. Typically 1 bottle of a 1:10 dilute mixture of soap concentrate is good for 2 or 3 cars before the next refill. This is true for most of the models.


Like earlier models, this one also has a knob to control soap thickness and spray angle.

This one may not look fancy branded, but don’t let that stop you from picking up a good choice.

6. MTM Hydro Foam Cannon Lance


MTM Hydro, based in Italy, is the trusted manufacturer of hydro foam cannon. They produce great products for automobile detailing as well as pressure washer parts.

Key Points at a Glance:

  • 8 – 5.3 GPM
  • Adjustable fan blades (Foam jet angle)
  • Large bottle
  • Also good for home cleaning

Someone, who wants a professional foam wash in a budget must consider this one. This is surely going to give you a feel of high professional foaming touch in a short budget.

Ideal for a 3000 psi pressure washer with a maximum range of 5000 psi pressure washer. The main issue, GPM is a maximum of 5.3 GPM and minimum of 1.8 GPM to suck the detergent.

Adjustable fan blades are present for wider and pointy foam angle and a knob (as always) for foam thickness control. In addition, the combination of power and GPM can cut serious grime from your car.


I do not recommend this for T type connector as they won’t fit. Rather than that, this is also made with a brass connector to stay on top. However, there are very negligible complains of rust issue.

7. Foseal Jet Wash Pressure Washer Adjustable Foam Cannon


I have known Foseal for wi-fi car data diagnostic reader, then I found this, a foam cannon. This foam cannon is really great! If you do not want to pay extra bucks on Chemical guys (neither do I), you need to consider this.

Key Points at a Glance:

  • Brass connector
  • 32-ounce bottle
  • Good strong bottle
  • The soap adjust knob is of brass (super interesting!)

I cannot ensure the brand value except the great quality I found. With a 32-ounce capacity bottle, it starts throwing out foam starting from 1000 PSI. That is a decent size bottle like the fancy brands have.

This produces a thick layer of foam under a decent amount of price tag. Regardless of the price tag, the bottle is quite tough. On top of it, they have a brass connector for zero water spillage.

With the save money be happy tag, this sturdy piece lasts a while. With the 1/4” quick disconnecting nozzle this is easy to use too. Combining with a good pressure washer and perfect nozzle fit this is capable of competing for any professional grade foam wash.


However, nothing is perfect. This item also has some bad reviews that are easy to opt out.

Best Foam Cannon Buying Guide (Complete Tip)

I have mentioned a few brands that are up to the mark. Yet, you should consider some steps before ending up with a wrong one in the process of selecting the best cannon.

Also, I am going to disclose the secrets for taking the best advantages of a foam cannon.

Foam Gun vs Foam Cannon: What Are The Differences?

You have already noticed or you knew about foam gun, which we are definitely not talking here about. So, you might be wondering what the actual difference between these two is?

foam gun vs foam cannon

Well, yes, there are some certain differences in outlook and features. And the main thing that makes them different is that one is a gun and other is cannon (!).

To be more specific, the foam gun fits with a typical hose. This makes it simpler to use but with some limitations.

  • As it fits with a garden hose the force or pressure it generates is disappointing to mention
  • You can understand, using low-pressure water extensively, this can only generate some foam which is really weak. The foam it generates won’t stay on the body and quickly runs off.
  • However, using low-pressure water does not mean less water. In practical it ends up using a big amount of water, which is a total waste.

As you already know, pressure washer uses huge pressure to generate water power. This pressurized water sucks up the detergent from foam cannon and mixes up with air to generate a thick layer of foam.

This sounds like using some extra setup like brass connector. This extra setup makes it super easy to set up with a pressure washer nozzle, just like a tap in! There are some great features too:

  • Generate extra thick layer of foam that does not run off. Which ensures super cleaning, like a professional car washing. The thicker the foam layer, the longer the stay, the premium finish is easier to get.
  • High-pressure water ensures the use of less water and soap yet a proper foam thickness. This makes foam cannon more efficient over foam gun.
  • If you have a car full of dirt and grime, using a foam cannon is wise than using soap and towel by hand all over your car. Foam it up and sit tight.

I always use a foam cannon and forgot the bucket full of soap and towel for wiping. Just foaming it up from the first step makes me feel a lot relaxed.

The Best Soap for Foam Cannon

One more thing people suffer to decide is foam cannon soap.

While buying this item all you need to consider is the thickness and great suds. A product that should not damage the car paint or wax protection but wash away all dirt and spots.

A soap that does not leave water spots is also a good one. However, shuffling from all the products available in the market and finding the best one is tough.

Here’s a quick pick of best one, keeping in mind the above-mentioned features of a good foam cannon soap.

How To Use Foam Cannon Effectively

This is controversial, whether you need to pre-wash before foaming up or not. However, let me assure you, there is literally no problem if you skip pre-wash.

The purpose of pre-wash is to remove the hard speck of dirt or debris from the surface. This keeps you on the safe side from making a scratch on the paint job. However, this is an extra step when you have only a pressure washer to work with.

Now, with a foam cannon you can, there is no need to pre-wash with plain water which saves a good amount of time. All you need to get started is a foam cannon and a pressure washer.

But how do you wash your car with a foam cannon exactly? Please check my article on how to adjust foam cannon for thicker foam first.

Use Foam Cannon Step By Step-

  • The first thing you need is to grab a foam cannon and pressure washer
  • Unscrew the brass connector from foam cannon body
  • Fill the bottle with water (lukewarm is better)
  • Add 1-3 ounces of your favorite car wash shampoo or soap (recommended)
  • Attach the bottle again with the brass connector part tightly
  • Connect with pressure washer spray gun lance by the quick disconnect nozzle of foam cannon
  • Start using the pressure washer until the air is purged or the foam comes out

While the foam is sprayed on your car, remember to spin the foam volume control knob for foam thickness you desire. There is also a plastic adjustable nozzle to control the angle of foam spray.

Here’s a video describing how to wash using a foam cannon.

The next step requires you to let the foam sit for a couple of minutes. This way it can grasp all the dirt and mud from your car easily.

Now, finally, take that dirt from your car! Use a pressure washer to work with the water jet from top to bottom. You do not want to blast dirt up onto the car from the ground by washing from bottom to top.

By now, you should see a shine on your car. Leave as it is, let dry and use a car wax for stunning shine like a pro.

How Does GPM Affect When Using Foam Cannon

A hard question but the answer is simple.

I know, this is hard when you notice your pressure washer has a GPM lower than the rated GPM of your newly bought foam cannon.

Don’t just throw them away. Because they would work properly. All you need is to switch to a small orifice.

Fortunately, most of the manufacturers pack them together. If it does not include in the package, you need to order them separately.

Maintaining You Foam Cannon

This might sound weird to you but this is essential.

People tend to (including me) through away and forget their foam cannon after the washing is done leaving soap mixture in the bottle. This generates a calcium sludge that hampers foam generation.

This situation can also reduce the pressure that it needs to operate.

You can already understand this is absolutely mandatory to empty and clean the foam cannon before putting it away for a long time.

Frequently Asked Questions

How much PSI does a foam cannon need?

Typically, the majority of foam cannons will require a PSI of between 1,000 and 3,000 PSI to be able to operate as they are supposed to. The number increases depending on whether you want a foam cannon that is light or heavy-duty.

Most light and medium-duty foam cannons will require a PSI of between 1,400 and 2,500 and anything between 2,500 and 3,000 PSI would be classed as heavy-duty.

Different foam cannons will require different PSIs and there is no correct answer for them all, so you must double-check the requirements for the specific foam cannon that you are considering purchasing.

In fact, one of the only clear differences that you will notice between foam cannons is often the name of the brand that is selling them.

As you look through foam cannons, it is very difficult to find any differential factors between them as most foam cannons will complete one simple job, so don’t be surprised if there appear to be no out-standing features for each device as this is often the case with foam cannons.

While it is advised that you use a highly concentrated soap, you will need to dilute these soaps down before using them with your foam cannon.

It is important that you use a highly concentrated soap as the weaker options will not be able to produce a thick foam when added to the cannon, leaving you with liquid rather than the shaving foam texture you may desire.

But as long as it is highly concentrated, there is no specific or special soap that you must use for your foam cannon, giving you lots of flexibility when buying.

A cheaper foam cannon can be very tempting, and in general, they are very good value.

But one issue with cheaper foam cannons is that they tend to have larger gaps for the soap and water to pass through in the quick connection, and this allows more water to pass through than soap which can often result in thinner foam coating your vehicle.

To get more foam, you should make this gap smaller. To do this, you need to remove the top piece of your foam cannon and use a wrench to remove the quick connection off of your gun.

With that removed, you can use a flat-head screwdriver to remove the orifice ready for replacement. You can then replace this orifice with a smaller orifice and this will allow you to get more foam out of your cannon.

For the best results, we would recommend replacing it with a 1.1mm orifice, but there are lots of other excellent options that will allow you to get more foam out of your cannon. 

Do you scrub after foam cannon?

No, you shouldn’t scrub your vehicle after you use a foam cannon on it. One of the main benefits of cleaning your car with a foam cannon is that it does not scratch the surface of your vehicle.

If you scrub your vehicle after applying the foam you run the risk of scratching the dirt into your vehicle’s surface, so you shouldn’t scrub it. Instead, you should use the foam cannon and then allow the foam to stand for a couple of minutes.

You should then rinse the foam off with water. Once you have cleared the soap, you can then scrub your vehicle with a soap and water solution if you want, but you should never scrub your car’s surface when it is coated with foam from the cannon.

Does foam clean better?

While there are some clear cleaning benefits that foam offers, foam doesn’t necessarily clean better than other cleaning methods. The amount of foam that you use when cleaning also does not have an impact on how well the foam will clean your vehicle, but it definitely is more aesthetically pleasing.

As we have said, one of the clear benefits that foam from a foam cannon has over other cleaning methods is that it allows you to retain the new shine that comes with your vehicle, which can make the paintwork look much nicer than other cleaning methods can.

Cleaning with foam is also often much quicker than other cleaning methods, as it does not require you to scrub the surface of your vehicle. So while cleaning with foam isn’t necessarily better, it does have some clear benefits that other cleaning methods do not offer. 

Can you use a foam cannon with a garden hose?

Yes, you can use your foam cannon with a garden hose. This is great as not everyone has a power washer available to them, but it is worth noting that you will not get the same effect with a garden hose as you would with a pressure washer.

To use a garden hose with your foam cannon, all you need to do is hook the foam cannon up to the garden hose in the same way that you would connect the foam cannon to the power washer.

This method works well but there are noticeable differences between using your foam cannon with a garden hose rather than a pressure washer.

The main one being that the quality of the foam will be much more liquidy rather than foamy. This doesn’t impact the foam’s cleaning ability, but it doesn’t look as nice when you are cleaning it.

What is the soap to water ratio for foam cannon?

One of the hardest things about using a foam cannon is trying to get the soap to water ratio correct. Most soap formulas will need you to dilute them before using them with your foam cannon due to the high concentration.

For the best results, you should aim to dilute a high concentration soap at a ratio of 1:16. So that is 1 part high-concentration soap, and 16 parts water, as this will highly dilute the soap.

If your vehicle is more dirty than usual, you should instead use a ratio of either 2:16 or 3:16 to get your car looking like new again. This ratio of soap will create an excellent foam that will be able to clean your car, and will also be aesthetically pleasing which is a big part of using a foam cannon when cleaning your vehicle. 

Should you rinse car before snow foam?

To generate better foam, it is best that you rinse your car with fresh water. When the surface is wet, the foam will be able to work better with your vehicle and create a cleaner look. When it comes to using a foam cannon on your vehicle, water is very important.

Rinsing your car before you use the foam cannon will help it to clean better, but the type of water that you use when diluting the soap is also important.

For the best results, you should use warm water when mixing the soap solution, rather than cold water. Warm water will generate larger suds which will be able to clean your car more successfully.

This warm foam solution combined with the water that is already coating your vehicle from pre-rinsing will improve the cleaning experience and get your vehicle looking as good as new.
