Being able to carry around the washer and the water source, without being connected to any mains power or tap, makes a lot of jobs much easier. If you want something that will clean all your patio furniture, I’d look for another that uses an external water source. I can see myself taking this camping to clean plates, wash off footwear, and clean the car window screen after a trip down a wet motorway. Basically – gentle tasks that don’t require a lot of power. The Oasser Portable Electric Pressure Washer is the best portable pressure washer for car cleaning. It weighs just 7.2 kg and has a maximum working pressure of 125 bar. The rated working pressure is 75 bar, so it’s suitable for cleaning your car but isn’t so high powered that it’ll damage the paintwork.

It’s possible to buy cordless pressure washers with less pressure, of around 5 bar. These have the same pressure as a garden hose, but can still be useful due to their portable nature. Whereas you mustn’t use a 20 bar pressure washer to clean a pet, you could use a 5-bar option to hose them down. 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.Some models are better suited to hosing down the bikes after going down a muddy trail, whilst others might be too powerful for this job. Equally, you might be keen to remove dried-on stains, in which case you’ll want a lot of power.

The main benefit of going cordless is the unrestricted access it brings. Save time unravelling the hose pipe and extension cables and opt to clean better under pressure. For delicate jobs, like cleaning a grubby dog, choose a bar pressure of less than 5 and a flow rate below 2 L/min. Of course, you should still test it on your hand first, but cordless pressure washers can be a great way to stop too much mud entering your car or house!

Design: When testing the design of each pressure washer, I considered portability, whether they had a compact size that was easy to store, the hose and cord storage, whether there were handy features like a carry handle or strap, and whether they were built well, with sturdy construction and durable parts. Models that ranged from 30 to 45 cm in height, 30 to 45 cm in width, and 25 to 35 cm in depth were deemed the most suitable for everyday users, as this size made them far easier to store and carry around. Those with a sturdy handle, strap, or cord storage were also given higher marks.This is not high-powered machine and it doesn’t claim to clean your patio. I think this cordless power washer is pretty good for its claims but removing dried mud and bird mess took a lot of soaking and the water ran out. The biggest problem is always going to be how long your battery powered pressure washer will last. This can vary quite dramatically between cordless pressure washers, and the charging time is also worth bearing in mind. 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. It doesn’t have quite as much reach as some others – the jet itself doesn’t stretch quite as far, and there’s no extension lance, so it’s not quite so good for long-range jobs. In particular, it feels heavier than others, possibly down to its basic, non-ergonomic design. For this reason, it’s not quite as good for jobs such as cleaning the windows.

The nozzle has one spray pattern, whereas other machines have a variety of jets, so it’s not all that versatile. Power & Performance: The main factors I tested for power and performance were each pressure washer’s bar pressure and motor type. Adjustable pressure settings are a must, so models with high, low, and “turbo” settings that range from 5 – over 100 bar pressure were rated the highest. I was also looking for models with brushless motors, as these are the best you can buy. Furthermore, I assessed each pressure washer’s flow rate and nozzle and spray patterns – washers with variable spray settings from 0 – 40 degrees were rated best, as these improved the versatility of the tool. The best way to describe this cordless pressure washer is basic but powerful. It’s certainly capable of doing the majority of jobs that you would require from a cordless model and I think it’s the best cordless pressure washer to buy on a budget.
