A final point worth noting: if cleaning windows is your main priority, you’ll need a washer with a long reach. Look for a hose of around 6 m so that you’re not tethered to your water source . 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!

Too little pressure and the job takes hours, too much pressure and you can damage paintwork and pointing. Pressure is all-important when you’re trying to choose the best portable pressure washer for your needs.

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. This pressure washer is simple to use and easy to put together. There are just two screws required to attach the handle, so no complex assembly. They’re particularly useful for taking with you on the go – on camping trips or walks – and for cleaning cars and bikes without being tethered to mains power. 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.

The main difference between power washing vs pressure washing is the heat. The jet wash in a power washing machine uses heated water, whereas the water in a pressure washer is not heated. Some may say jet washers are more effective on really stubborn stains as the heat can add another layer to breaking the stain down. What to read next:Adjustable Nozzle: This cordless pressure washer comes with an 0°-40° adjustable nozzle, it has different spray pattern to suit your various washing needs. The pressure washer also comes with a 300ml foam pot with nozzle for fast foaming and better cleaning. 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. This is something that’s important to consider. What do you want to use your cordless portable pressure washer for?

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. 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. To remove small amounts of algae from patios, you’ll need a washer with at least 25-bar pressure . Be aware that cordless pressure washers are great for general cleaning, but if your main aim is to lift stubborn stains, you may need a mains-powered machine with around 100 bar pressure. When keeping items in the car boot for a long time, it’s easy for them to roll around and for small parts to get lost in the melee.A washer with more than 22 bar should be capable of removing most types of dirt. A good pressure washer with this power can usually remove algae on patios using a fine ‘pencil’ jet. You may have to get more ‘hands on’ with a lower pressure portable washer than you would with a mains-powered pressure washer. For example, using a brush attachment can help shift dirt.
