Cut the cord! Almost every power tool out there is cutting the cord in one way or another. Even car companies are jumping on the battery bandwagon (ie:Tesla) essentially cutting the cord to the fossil fuel grid.
So what about the pressure washer industry? Can it be dominated by extremely portable cordless battery powered pressure washers in the next few years? We’ll review some of the industry leaders, but you may not like my answer…
There is actually not a whole lot to choose from. Battery technology just cant equal the typical electric or gas pressure washer specs. For context, a Tesla Model S battery weighs 1200lbs! In comparison a Chevy small block V8 weighs in at only 575 lbs…
To dominate the pressure washer industry a cordless unit must run 2-3 hours till next charge and provide the exact PSI like an electric or gas one.
How is it that laptops took over desktops? Battery backup and exact performance like a desktop plus mobility. This is the same for pressure washers too.
If manufacturers can do the same for a pressure washer, this industry might be dominated cordless pressure washers in the next years like so many other industries. The emergence, and maybe even dominance, of cordless power washers is inevitable. As the demand for battery operated pressure washers increases, cost will decrease.
In addition to that, lithium-ion batteries are so popular. And the capacity of this kind of battery is increasing day by day due to continuous research.
So, it’s obvious that the cordless pressure washer market is increasing but the current situation is not exactly like the electric car industry boom, it’s slim pickings…
There really are only a few models worth mentioning:

The Cordless Pressure Washer is not Popular Yet: Reasons
When manufacturers produce a product, they have to keep three things in mind.
- Lower cost
- Better performance
In the current situation, an electric pressure washer might be a good one for lower cost and compactness. But gas pressure washers are far more powerful. It depends on what you want to do with it.
While manufacturing cordless pressure washers, engineers cannot simply offer the basic three criteria of a good product all in one.
To compete with an electric or gas pressure washer, a cordless pressure washer must have great battery backup, more than 2000 psi pressure and still has to be lightweight. This is literally impossible in the current situation.
The battery would be so heavy and people would never buy those. Rather, customers would go for an electric or gas washer instead.
The good news is the portable cordless pressure washers in the market now aren’t that bulky. The bad news is, the available models are not cheap and are not very powerful yet.
If your criteria is to replace an electric or gas pressure washer, then you’ll be disappointed. If you want something for on the road small jobs, RV or camping, washing saltwater of your boat ect… then the following choices might fit the bill.
Best Cordless Pressure Washers in the Market (For Now)
Well, there is no populated market out there in the US like the rest of the markets. Unlike gas or electric pressure washers, cordless pressure washers did not yet take over the pressure washer market.
There are only two mentionable battery operated pressure washers at this moment. I don’t know if there is more.
The pressure washers I am going to mention can somehow compete with the existing gas or electric washers by reaching 1500 PSI. Others are around 300-500 PSI, which is slightly better than a garden hose.
This one is the only cordless pressure washer that has the features of a typical pressure washer selling online in the US.
Sun Joe has been developing cordless pressure washer for a few years. This model is a further development of their previous model SPX 6000. The improvements are mainly on the TSS (total stop system: automatically shuts off pump when trigger is not engaged to save energy and prolong pump life and bucket supply).
The key features it has are:
- 800 PSI with the bucket and 1160 PSI with a hose
- Detachable bucket
- 40V – 5AH rechargeable battery
- 0.79 GPM
- 29 lbs. weight
- 5.3 Gallons bucket
The numbers, though not great, are actually the best stats of the cordless power washers reviewed here. It will serve well enough while you are out in the field or in a remote place where there is no electric connection. Detachable bucket system is handy frees you from the garden hose when necessary, all of which makes this unit the most portable.
- Battery backup
- Mobile and rolls smoothly
- Pressure select option
- Quality hose and lightweight
- The bucket has an odd handle to carry
- Not enough pressure for big problem areas
- High wear possibility in battery compartment door
- Wheels do not promise longevity
The 40V 5.0-Ah battery provides back up for 30-40 minutes in continuous pressure washing, enough for at least a couple car washings.
The top-loading detachable bucket is made better in the new improved model. This power washer is perfect for a little on the road RV cleaning or any on the road or remote cleaning project. The covers are built better to stop spillage while pulling around.
There are three pressure selections, 507 PSI/650 PSI/800 PSI for the bucket. To achieve the 1160 PSI you need to attach a garden hose with water supply. Your home water pressure is required to get that extra 1160 PSI. As always, the smaller the nozzle angle the higher the PSI.
So this product is new to the neighbor and has some nice features compared to others in the ‘cordless’ category. Two batteries is a must (it’s surprising how many cordless units don’t come with two batteries). Nothings worse than getting a job halfway done then having to stop to charge a battery…
Also, this guy is as powerful as the Sun Joe reviewed above, but even more portable. 960psi at 1.2gpm. Easy adjust spray, much like a garden hose spray gun. Supply water from a bucket or hose.
Here’s an Amazon review that describes a best use scenario:
This is great if you aren’t expecting to clean a deck, driveway or fence. This is NOT a medium or heavy duty pressure washer and that is NOT a knock. For what I use it for it’s great. I use it as a portable car washer. I put a 40 gallon tank in my truck and all I do is pull this out and go to work. I have a self-contained car was system in my truck. My truck is a looker not a worker so I wash it many times a week. Keeps my custom chrome wheels in perfect condition all the time.

- Dual rechargeable batteries

- Gun Continues to Run Water if the Hose is on.
- Light Duty Projects Only
- Difficult to Find Replacement Batteries
Hold on. Are you surprised already? You should be. This so-called truly portable power washer is only 320 PSI pressure generator.
This is the closest one to be called a portable cordless pressure washer available.
Why I considered this model is only because of its portability.
In the current situation, people are looking for a portable option while buying a cordless pressure washer. But even corded ones tend to be portable...
People make a mistake while selecting a cordless one is expecting everything in a budget. While the Worx is great in innovation it lacks in power. If customers are looking for similar performance with a similar price from a corded and cordless one, they are going to be disappointed.
One thing is clear. This Worx cordless pressure washer is truly uber portable, it still lacks the power to compare with corded power washers.
Let’s have a look at the features:
- Great portability
- Five spray angles
- 2 rechargeable batteries with a dual charger 20V – 2 AH
- Battery backup is about 25 minutes
- It draws water from any available source
- Fully Cordless
This thing is not for cleaning your driveway. Or for cleaning heavy stains like paint. You can wash your car, wash away some bird poop or clean your window. A great option for a portable washer.
With this second Worx model (they offer several actually), they did something clever. Worx offers a lot of cordless tools in their line up and have designed interoperability into their batteries. Mix and swap keeps your portable tool working longer and you don’t have 5 different battery types laying around.
So, maintaining the same standard batteries, they combined two 20v batteries into one portable pressure washer to give you a 40v tool without having to invest in new batteries. This bumps up the specs to 450 PSI and .9GPM
- Dual speeds (PSI) to prolong battery life
- Five spray angles
- Dual port charger – you can charge both your 20V battery concurrently
- Battery Charge Indicator
- Offers various package options
SUMMARY: Best Review Of Cordless Battery Powered Pressure Washers 2020
- Sun Joe XPX6001C-XR: 1160 PSI with a hose, 0.79 GPM
- mrliance 40V: 960 PSI, 1.2 GPM
- Worx WO7046 Hydroshot Dual Charger: 320 PSI & .5GPM
- Worx WG644 Power Share 40v Hydroshot: 450PSI & .9GPM
Should You Get One?
These are not the only models. Some manufacturers like Karcher, Greenworks are manufacturing cordless pressure washers too, but the industry is in it’s infancy.
I’m sure there are some specialized circumstances that might warrant one, light duty washing, rinsing saltwater off your Kayak ect…
But the fact is, your gonna have to drag a hose around for most jobs anyways. Dragging an extension cord too, really isn’t much more hassle. If you don’t need anymore water than you can fit in a bucket, then maybe cordless is the way to go…
For light duty and no electrical outlet handy… maybe. Then again don’t forget gas power washers are cordless too;)
