5 Best Battery-Powered Pressure Washers For Cars

My plan was to give you a list of 7 or 10 best cordless pressure washers, but to be honest, there are not so many worthy products that I could recommend to you (at least not reasonably priced ones). So, there will be five portable pressure washers only.

1. Ryobi 40V Cordless Electric Pressure Washer: BEST OVERALL

The Ryobi 40V Cordless Power Washer is my go-to for an easy car wash when there’s no plug around. Ryobi’s gear has always been solid for me, and this pressure washer is no exception.

It’s a cinch to lug around – just roll it to your car, extend the handle, and off you go. The cleaning power? Spot on. It hits that sweet spot with 1500 PSI, and if you need to tackle something stubborn, just hit the boost.

Battery life is just right. You’ll zip through a car wash on a single charge, and if you’re quick, maybe even two.

It’s a flexible little machine, too. Hook it up to your hose, or use the tank that comes with it. Soap? There’s a spot for that as well. The hose and nozzles give you plenty of reach and options for different cleaning jobs.

And the warranty is a real comfort—5 years on the tool, 3 on the batteries. Ryobi’s pretty much got you covered, which makes it a solid pick in my book.

PROS

  • Great portability because of wheels and extendable handle
  • Fantastic PSI for washing vehicles
  • 5-gallon water tank included with the device
  • High-quality device
  • Very long warranty

CONS

  • The soap tank shouldn’t be used too often
  • Battery charging time of 6 hours

2. Greenworks 40V Cordless Pressure Washer

The GreenWorks Cordless Pressure Washer is a solid, budget-conscious option I’ve found reliable for regular car washes. Its 800 PSI and 1.0 GPM output might not pack the heft of higher-end models, but it’s ample for essential cleanings.

You’ll have to invest in GreenWorks batteries separately. I suggest two for extended cleaning sessions, though one battery can suffice if needed.

For water, it’s versatile—you can either fill the detachable tank or hook it up to a garden hose. It comes with a trio of nozzles, and from experience, the 40° nozzle works best for a gentle yet thorough clean.

This model is supported by a 3-year warranty for both the tool and the batteries you add on. In my use, it’s proved to be a straightforward, economical tool that gets the job done.

PROS

  • You can use hot water too
  • Some people claim that it can last for up to an hour (with two batteries)

CONS

  • No wheels
  • No lid
  • No batteries included

3. Ryobi 40V Battery Pressure Washer

The RYOBI 40V HP EZClean Power Cleaner packs a hefty 600 PSI, making it an ideal, portable solution for quick cleaning tasks. Its small size belies its power, easily stowed in a car trunk for on-the-go use.

I’ve been particularly impressed with the adjustable pressure settings and the 3-in-1 nozzle, allowing me to shift from delicate rinses to blasting away tough dirt with ease. The 20 ft. siphon hose is also a standout, drawing water from any fresh source, which came in handy during outdoor adventures.

Coming with a robust 40V 2.0 Ah battery and charger, it’s compatible with other RYOBI 40V tools, a big win for tool enthusiasts. With its water-resistant battery enclosure and auxiliary handle, it’s both durable and easy to maneuver.

All in all, the RYOBI 40V Power Cleaner is surprisingly mighty for its size, a perfect fit for anyone needing a reliable clean without the bulk.

PROS

  • Small in size yet powerful.
  • Comes with batteries.
  • Batteries fit all Ryobi devices.

CONS

  • The handle seems kind of strange to me.
  • I’d love the wand to be slightly longer.

4. WORX Hydroshot Hand-Held Cordless Pressure Washer

The Worx Handheld Pressure Washer offers practicality much like the RYOBI 40V HP EZClean, but it comes with a bit more heft due to the dual battery setup. Even with the extra weight, it’s a powerful contender, pushing out 725 PSI at a max flow rate of 1.2 GPM — impressive for a handheld unit and a notable step up from the RYOBI’s 600 PSI.

Battery-wise, you have options with the Worx: go for two 20V 2.0Ah batteries for extended power, or scale back as needed. It’s less about whether it can last — up to 50 minutes on eco mode is generous — and more about how much power you need on hand.

While both models can pull water from any fresh source, the Worx’s hose is on par at 20 feet, though a longer hose would give it an edge over the RYOBI. Its all-in-one nozzle doesn’t skimp on versatility either, with settings ranging from 0° to 40° for various cleaning needs.

Charging is efficient with the Worx, thanks to a charger that juices up two batteries simultaneously in two hours. And while it’s slightly heavier than the RYOBI, it’s a strong alternative for those who prioritize cleaning power and battery flexibility.

Remember to check the return policy carefully; although Worx generally offers a 30-day return window, some users have reported less-than-full refunds, unlike the straightforward warranty service I’ve experienced with RYOBI.

PROS

  • Dual-battery charger
  • Great working time
  • Very convenient

CONS

  • It can be exhausting to wash more than one car with this device (because of the weight)
  • Lack of information about warranty

5. Black+Decker 20V Cordless Pressure Washer: Best Budget

The Black+Decker 20V Power Cleaner stands out for its power, pushing out a strong 350 psi. That’s five times the pressure you’d get from a regular garden hose, making it a potent tool for blasting away stubborn grime.

This cleaner is a marvel of flexibility, easily connecting to a garden hose or drawing water from any fresh source. It’s perfect for spontaneous washes wherever you are.

The integrated adjustable nozzle is a true game changer, allowing you to switch between pressures for various tasks. I’ve found this feature incredibly useful when dealing with different cleaning challenges.

For those delicate tasks, the included short wand is a gentle giant, ideal for watering plants without damage.

It’s part of the 20V MAX* POWERCONNECT™ battery system, which means battery swapping is a breeze if you’re invested in the Black+Decker ecosystem.

The 1.5Ah battery might not last as long as others, but it’s more than sufficient for quick, efficient cleanups. Considering the price point, this cleaner is a steal, providing excellent value and reliable performance for all your light-duty cleaning needs.

PROS

  • Best budget option.
  • Fit all Black+Decker batteries.
  • Lightweight.

CONS

  • The included battery is too small, and you might want to buy a larger one from Black+Decker.

Are Cordless Pressure Washers Good For Washing Cars?

Let’s get the things straight. Most of the cordless pressure washers aren’t comparable to the corded or gasoline ones. They just can’t provide you with so much power. However, high-quality battery-powered pressure washers, such as Ryobi cordless pressure washers, will provide you with more than enough pressure to wash cars (even the filthy ones).

As you can see on the list, not all pressure washers have plenty of PSI. That doesn’t make them bad for washing cars but don’t expect miracles when trying to clean some stuck bugs from your car (following this method will help you remove them).

In my opinion, if you don’t have a garden or a place to store and use the “real” pressure washers, buying a cordless pressure washer is a fantastic thing to do. That way, you’ll be able to wash your car by yourself, anytime, anywhere. That’s the biggest advantage of all cordless tools, including cordless pressure washers.

If you decide to buy some other pressure washers that aren’t on this list, try to buy one with at least 1000PSI, and check reviews to see if the delivered PSI is as advertised.
