What to Look for When Purchasing the Best Cordless Pressure Washer

When you are on the hunt for the best cordless pressure washer, you need to have a good idea about what you want to accomplish the pressure washer. This can help you narrow down your choices and find the right one for the job.

Paint Stripping

If you are trying to strip paint, then a cordless pressure washer is probably not the right tool for the job. To take off paint, you need to have a minimum pressure of around 2,500 PSI. You simply can’t always get that much power with a cordless device.

Deep Cleaning

If you are looking to clean the dirt and muck off your sidewalk or deck, then you want to have at least 1,000 to 1,500 PSI. Again, you may not have the maximum power you need with a cordless pressure washer for this job. You will still see results and can clean residue off of vinyl siding, though.

Cleaning Up Mud

To clean up mud, you should have around 500 PSI, although you can also get away with around 130 PSI if it isn’t a huge caked-on mess. A cordless pressure washer is ideal for cleaning mud and debris off of bikes and kayaks after a fun outing.

Car Washing

A cordless pressure washer is also good for cleaning the cars in your driveway. If it is light enough pressure, you will also find them useful for washing your dog, watering the plants, and cleaning your camping equipment.

Tank or No Tank

With cordless pressure washers, you will find two types: one with a tank and one without. A tankless pressure washer is going to require a close-by water source like a bucket of water. A pressure washer with a tank, on the other hand, carries the water with it, but you will still need to fill it up from time to time.


Battery pressure washers may be more affordable (in some cases) and compact, but they are still not as popular as the full-size pressure washers that have more power. However, if you want something for the smaller jobs around the home, then a battery-powered pressure washer is a good choice.

Just make sure that what you choose has a good battery backup, and it is lightweight. Get as high of a PSI as possible as well, so you can accomplish more. 2,000 PSI is ideal. Another bright side to purchasing a cordless pressure washer? They are small and compact, so they store easily.

Pressure Washer FAQ

Still have questions when it comes to pressure washers and what you can do around the home with them? Read through our FAQ below for answers.

What type of detergent do I need to use?

First, you have to find out whether the unit you are about to purchase has a detergent or soap tank. If there is a tank, then you can use the cleaning detergent that will work best for the job you are doing.

How frequently should I use a pressure washer?

The beauty of having a cordless pressure washer in the home is being able to pull it out quickly and easily when you find small cleaning jobs that need to be done around the home. It can be used several times per week for a variety of different jobs including washing the cars, washing the mud off of bicycles, cleaning camping gear, washing down lawn furniture, watering the garden, and so much more.

Do portable pressure washers come with wheels?

Yes. Some models do come with wheels and make it easier and more convenient to use and to transport.

How much bar PSI do I need to use for my car?

A pressure washer with around 700 PSI is adequate for car cleaning. It is when you get above the 1200 PSI mark that you should consider using something other than a pressure washer because, at a PSI above 1200, there is a chance you can damage the paint on the car.

Can you pressure wash without an outside tap?

Yes, if you have one of the cordless pressure washers on our list you can. Many of these cordless pressure washers come with an attached water tank. All you need to do is fill the tank and get right to the cleaning job at hand. Larger, corded pressure washers, on the other hand, will require a close-by water source to tap into.

Do you have to use soap with a pressure washer?

Not necessarily. However, if you do want the option to use cleaning detergents for your cleaning tasks, you can opt for a pressure washer with a detergent tube.

What is the difference between a pressure washer and a power washer?

While very similar, the main difference between a pressure washer and power washer is the use of heat. The jet washing action of a power washer uses heated water while the water being used in a pressure washer is not heated.
