Buyer’s Guide

There are a few factors to take into consideration when purchasing a commercial pressure washer, but it mainly comes down to whether you choose a hot or cold water pressure washer, the type of power, and the type of pump. 

A commercial pressure washer is an investment that you will want to withstand the test of time, especially if you’re using it on a regular or daily basis to clean.

Don’t be persuaded into buying a lower quality pressure washer, as what you might initially save, you’ll end up paying for later down the line. Save yourself the trouble and make sure that you do your own research in order to find a good quality pressure. 

Take a look at the factors below before buying a commercial pressure washer. 

Type of pressure washer – Hot Vs. cold water pressure washers  

When choosing the right commercial pressure washer for you, you’ll need to weigh up whether you should buy a hot or cold water pressure washer. 

Cold-water pressure washers are arguably the most common type of pressure washer and work well to penetrate dirt in order to wash it away.

The use of pressure can be very effective in cleaning dirt and grime, although it may be less effective for certain types of cleaning tasks, such as getting rid of oil or grease. 

Hot water pressure washers are generally better at getting rid of oily or greasy deposits, as the heat of the hot water helps to soften and emulsify tougher stains so they can be loosened and washed away with less effort and work involved. 

Whether you choose a hot or cold water pressure washer, you will need to take into consideration the types of jobs that you think you’ll be carrying out with the pressure washer. You will also need to weigh up your priorities and personal preferences before going ahead with your purchase. 

Type of power  

When making your purchase, you will need to decide whether you’d prefer a gas or electric powdered commercial pressure washer. The type of power that you opt for will largely be up to your personal preference, but will also depend on where you intend to be cleaning. 

Electric – If you are confident that you will always be pressure washing near an electric outlet (like at a warehouse or factory) then your best bet is to get an electric pressure washer. Generally speaking, it requires less maintenance as you won’t have to worry about refueling, it is quieter and you can safely use it indoors, too! However, you might find the cost of the cleaning power to be higher. 

Gas – Gas, on the other hand, will offer you portability as well as more power for less cost. If you know you’re going to be moving around a lot, then a gas pressure washer will be more practical and convenient. This is especially true if you run a mobile cleaning business because you won’t have to search inside the customer’s house/establishment for electrical outlets. 

Whichever type of power you opt for, make sure that it compliments your lifestyle and what you intend to use the commercial pressure washer for. They’re designed to make cleaning easier, not harder, so make sure that the type of power isn’t going to hinder you in any way. 

Type of pump 

Something you’ll need to consider when choosing a commercial power washer is the type of pump that it has. 

Belt-drive pumps are one of your options. Belt-driven pressure washers require a gear reduction pulley system, whereby pumps turn more slowly. This means that less heat and vibrations will be emitted, which greatly decreases the chance of wear and tear, and is why you are more likely to find a belt-drive pump in a heavy-duty power washer as it is less likely to break.

Belt-driven pumps are the most suited for people that are professionally pressure washing on a regular basis, as you’ll require it to withstand the test of time more than someone that only occasionally uses it. 

On the other hand, you could choose a direct drive pump. Unlike a belt-driven pressure washer, a direct-drive pressure washer is directly connected to the engine itself, which means the washer runs at about the same speed as the engine itself. These pumps are usually made for household jobs, as the machine itself is easy to transport.

The direct connection does, however, mean that your pressure washer is more likely to degrade more quickly. Generally speaking, if pressure washing is part of your job but not something you do consistently, a direct drive pump will be sufficient enough for you. 

Keeping these differences in mind, you’ll be able to choose the type of pressure washer that’s best for you. Consider the type of jobs that you’ll want to be tackling with your pressure washer and go from there. 


A pressure washer’s power is measured in pounds per square inch (PSI). Therefore, an important factor that you’ll need to take into account is the PSI of your commercial pressure washer to ensure that it is powerful enough to undertake the job that you’re required to do. 

Generally speaking, you should try to choose a commercial power washer with a PSI of at least 3000.

The PSI that you require on a daily basis will also depend on the types of jobs that you intend to be doing, but you should generally always follow the 3000 PSI rule to ensure that it is capable of tackling those bigger jobs.

It is important to remember that the more powerful a pressure washer is, the more versatile the jobs you can undertake are! If you want to use a pressure washer that is suitable for a variety of cleaning tasks, then you need one that is versatile and can deliver a force of up to 3000 pounds per square inch. 

As a result, you should always make sure that you’re happy with the PSI before heading to the checkout. 


As an investment that you’ll want to last for years to come, you need to think about the durability of the commercial pressure washer that you choose.

Typically speaking, commercial pressure washers are able to withstand a lot more than a residential pressure washer, however, you still need to be cautious.

A good method of establishing whether a product is durable or not is to check the product reviews section. Here, customers will outline any issues that they’ve had with the product that you’re looking at and will reveal any problems that you could also face if you buy the pressure washer. 

As a result, you should always do your own research and check the product reviews section to ensure that you’re happy to proceed with your purchase. After all, no one wants to waste their money on a dud product!  


An important factor to consider before purchasing a commercial power washer is the duration of the warranty that it comes with. 

The warranty will cover you should anything go wrong with your purchase sooner than you had expected or if it arrives faulty.

As an investment that you’ll be using on a regular basis, you want to ensure that you don’t have to worry about something going wrong and that you’re purchasing a product that you can put your trust in. 

If you’re unsure about the warranty of a certain commercial pressure washer, your safest bet is to check the manufacturer’s website for more information. It is worth noting that warranty terms can differ between manufacturers and sellers, though, so you should always be sure to check both. 

To avoid disappointment, always make sure that you’re happy with the product’s warranty information before proceeding with your purchase. 

Frequently Asked Questions 

What PSI is a commercial pressure washer? 

You can easily identify whether a pressure washer is going to be cut out for a big, commercial job by looking at the PSI.  Generally speaking, you’ll be looking at around 3000 PSI for a commercial pressure washer.

Whilst heavy-duty pressure washers have a PSI of 2800 or more, commercial pressure washers are longer-lasting and pack more power with 3000 psi or more. As a result, you should look for a pressure washer that fits within this range. 

Is there a difference between a power washer and a pressure washer? 

Technically speaking, yes. but there is some debate on the terms.  They are most commonly used interchangeably

When differentiated, a power washer is a pressure washer that uses hot water.

A power washer uses a high-pressure stream of very hot water to blast away dirt and built-up grime from outdoor surfaces. The combination of high pressure and the temperature of the water makes it a powerful tool for removing dirt grime and all those truly stuck on materials from surfaces.
