My Top Recommended Portable Pressure Washers

For medium-difficulty jobs, I recommend a cordless pressure washer with around 20 – 22 bar pressure . This will be sufficient for most tasks such as hosing down muddy bikes, cleaning the car or washing windows. Some high-power washers have ECO settings which produce a lower-pressure jet. This allows their battery to last for longer and you can switch to high pressure only when it’s necessary. If you want something that will clean all your patio furniture, I’d look for another that uses an external water source. Not only does the Wilks-USA RX545i High Power Pressure Washer have the highest pressure output of all the pressure washers featured here, it also has the longest hose. It’s therefore a very powerful and versatile tool for cleaning around the home and garden. The 110 bar pressure allows it to make light work of a range of household cleaning tasks, including car washing, patio scrubbing and cleaning outdoor furniture. It comes with a detergent container and a range of spray nozzles for more effective cleaning.

Compact and versatile, this pressure washer can be lifted up and carried with just one hand. It has a 5 m cable, giving reasonable freedom to move around whilst using it. The hose is 6 m long, and the power cable is 5m, so you should be able to reach around cars and across small patios. If it does need moving, there are built-in wheels to help. If you want to use your cordless pressure washer for more delicate tasks, such as cleaning a grubby dog after a walk, you should look for something much gentler, around 5 bar. Weighing 9.2 kg, this compact Yard Force pressure washer is sufficiently portable. It has a neat build and a large carry handle. If you want to take your cordless pressure washer in the car, and hose down your mountain bike or dog after a day of fun in the great outdoors, consider a smaller model which can be transported easily.

Remember: battery life only refers to the time when the washer is on. Washing the car might take a total of 30 minutes, but you may only sporadically use the power washer for 10 minutes of that time. Noise: In terms of noise, I was looking for pressure washers that were sufficiently powerful yet remained quiet so they wouldn’t annoy the neighbours! Any models producing 80 dB of noise or less were marked higher, whereas excessively noisy models of 90 dB or above were marked down.
