When there are no power outlets or water connections, it’s much harder to wash the vehicle. Luckily, with technology advancing every single day, people have invented many battery-powered tools that can help you in your daily activities. When it comes to washing cars, having a power washer is extremely important, and today, I’ll show you my top picks for the best electric cordless pressure washers for cars so that you can wash your car anywhere, anytime.

The Summary Of Top Picks:

I’ll pay specific attention to some of the specs that are extremely important for proper car washing, such as PSI, can the pressure washer suck water from the bucket, how long the batteries last, what’s the cleaning power, etc. All in all, if you’re looking for a high-quality battery-powered pressure washer to wash your car, this article is for you.

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 reasonable priced ones). So, there’ll be five portable pressure washers only.

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

If you’re looking for the best possible cordless electric pressure washer for cars, this Ryobi RY40PW01DG9 cordless heavy-duty pressure washer is my number 1 recommendation. Ryobi is a well-known brand, and its products are made from high-quality materials. I had a chance to work with their drills, and I was amazed by the quality and durability.

It’s well-designed in a way that it’s easy to carry it everywhere. Wheels and an extendable handle make it easy to move around vehicles.

With 1500 PSI and 1.2 GPM, it’ll offer you more than enough water pressure for washing vehicles. It’s inside the range of 1200-1900 PSI, which is recommended pressure for washing vehicles. It usually starts with 1000 PSI, but when you turn on the boost pressure option, it ramps up to 1500 PSI.

To power this device, you’ll get two 40V 5.0Ah batteries, which will give you around 30 minutes of constant power without boost mode (1000 PSI), and 15 minutes of constant work with the boost mode turned on (1500 PSI). In my opinion, it’s enough to wash one or maybe two cars with a single charge.

You can connect this pressure washer to a standard garden hose, or you can use an included 5-gallon water tank (you could also use a bucket). Also, there’s an onboard detergent tank so that you can put some soap inside. The pressure hose on this device is 25 feet long.

With the device, you’ll also get three different spray nozzles. The standard 15° nozzle, soap nozzle, and turbo nozzle for much faster cleaning.

The great thing about this Ryobi cordless pressure washer is that you get a 5-year limited tool warranty, and a 3-year limited battery warranty, which is fantastic in my opinion.


  • 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


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

2. Sun Joe 24V-X2-PW1200 Battery Powered Pressure Washer

If you’re looking for a cheaper alternative to Ryobi, then this Sun Joe 24V X2 pressure washer is a fantastic choice. It’s almost double cheaper than the Ryobi one, but still offers some great specs that are important for washing vehicles.

The manufacturer claims that it can generate a maximum of ca. 1200 PSI, even though it’s more likely to be around 800-900 PSI, which is a bit low pressure. Anyway, since it’s a cordless device, I can’t say that it’s bad.

With this device, you’ll get two 24V 4.0Ah batteries, which will ensure that this powerful 600W motor can work up to 20 minutes constantly. It should be enough to wash two vehicles with one charge.

To connect this device to the water source, you can use an included detachable 6.6-gallon bucket, or you can connect it to a garden hose. The pressure hose is 20ft long.

With this device, you’ll get the 5-in-1 nozzle, which you can adapt based on your needs, and you’ll also get a soap sprayer which is fantastic for spraying cars with snow foam.

When it comes to warranty, there’s a 30-day return, refund, or replacement policy. You can also buy a protection plan for 2 or 3 years.


  • Great bang for the buck
  • Detachable water tank
  • Soap sprayer included
  • A quick battery charge of 2 hours only


  • Pressure may not be as advertised
  • Parts may not be compatible with other brands’ parts

3. Greenworks Cordless Pressure Washer

This GreenWorks cordless pressure washer is a convenient little device for washing cars designed similarly to the Sun Joe pressure washer. It’s much cheaper than other devices of similar design, but unfortunately, it doesn’t come with batteries included.

It has a power of 800 PSI and 1.0 GPM, which is not ideal for washing vehicles but is still considered good enough for maintenance washes. In this price range, it’s actually one of the better ones.

Unfortunately, batteries aren’t included in the package, but you can buy two 40V 2.0Ah batteries to power this device. It’ll even work with one battery only, but I suggest buying two to get extended run time. When buying batteries, make sure to choose the ones from GreenWorks only.

To get the water, you can use a detachable tank which is included, or you can connect the pressure washer to a standard garden hose for an unlimited source of water.

With this device, you’ll get three nozzles: 25°, 40°, and a soap nozzle. For washing vehicles, the most convenient one will be the 40° nozzle.

The warranty for this tool is great, you get a 3-year tool warranty, and when you buy batteries, they’ll have a 3-year warranty too.


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


  • No wheels
  • No lid
  • No batteries included

4. WORX Hydroshot Hand-Held Cordless Pressure Washer

This device is a great handheld battery-powered pressure washer for all of you who won’t mind an extra weight in your hand while washing cars. Even though the batteries will add some extra weight, since it’s handheld, it adds up to the convenience, since you can carry it literally everywhere.

It has a power output of 725 PSI with a max flow rate of 1.2 GPM, which is around 11 times higher pressure than the standard garden hose pressure. Again, it’s not perfect for washing extremely filthy vehicles, but for maintenance washes, it’ll be completely fine.

With this device, you’ll get two 20V 2.0Ah batteries, which are a total of 40V and 4.0Ah of power source. You can also choose to buy the tool with one battery, or without batteries. When it comes to efficiency, the batteries will last up to 50 minutes on eco mode, and about 30 minutes on max.

Worx cordless pressure washers can draw water from any water source such as lakes, pools, buckets, or a garden hose. The length of a high-pressure hose is 20 feet, which is fine but could be a bit better.

With this device, you won’t get any specific equipment. It comes with a convenient all-in-one nozzle that you can twist in order to adapt the angle (0°, 15°, 25°, 40°). The thing I like the most is the charger that can charge two batteries at once, and it takes only 2 hours to charge them.

The device is eligible for return, refund, or replacement within 30 days of receipt. However, some people complained about the refund policy (they didn’t get a full refund).


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


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

5. Canbrake 870PSI Handheld Cordless Pressure Washer: BUDGET OPTION

If you’re looking for a budget battery-powered pressure washer, then this might be the right option for you. One very interesting thing about this device is that you even get an LCD display that shows the percentage of the battery.

The Canbrake cordless pressure washer can provide you with around 870PSI, and a 2.22 GPM flow rate, which is really good for a device of this size.

It comes with a 15000mAh battery, which isn’t a lot but will provide you with enough power to wash one vehicle. Since batteries are attached to the wand, it’ll add up some extra weight. The battery should last for about 30 minutes.

In the package, you’ll get a 16-feet long hose that you can connect to any water source (lakes, buckets, etc.), or to a standard garden water outlet.

When it comes to equipment, you get plenty of them with this device. You’ll get a 6-in-1 adjustable nozzle, 4 individual nozzles (0°, 15°, 25°, and 40°), 2 water pipe connections, 2 faucet connections, 1 water bottle for foams, garden hose connector, 11L foldable bucket, foam pot, a filter, and even a suitcase. It’s just filled with equipment.

When it comes to warranty, there’s limited information. However, it’s eligible for a refund, and you can also buy a 3-year extended protection plan for $29.99 only.


  • Plenty of equipment provided with the device
  • Best budget


  • Can be heavy to carry around in your hands
  • Lack of warranty information
  • Pressure not as advertised

Are Cordless Pressure Washers Good Enough For Washing Car Detailers?

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 could see up 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 if the delivered PSI is as advertised.
