Max out on power and capability with the Karcher K4 Premium High Pressure Washer, which aced our at-home tests. This super versatile pressure washer is fully equipped to deal with a range of problems that might arise after a winter in the UK - we're talking lacklustre garden chairs, clogged gutters and sad-looking BBQs.

To tackle these tough jobs, our reviewer powered through the three pressure settings on the K4, using each of them to blast through dirt and grime, and get surfaces back to their original colour. When using this pressure washer, our expert found the trigger handle display which clearly shows which setting you're on especially useful. 

This sturdily-built washer is kitted out with everything you need to sort out both your garden and your car, and enabled our reviewer to easily clean her glass patio doors, car, stone patio and wooden sleeper pathway. With an RRP of £399.99, we know that this is a real investment, but if you want a pressure washer built to last that can take on practically any of your surfaces, and make your car gleam too, then you're onto a winner.

If you need high pressure then look elswehere

Do you think you need to have an outdoor tap or nearby plug socket to use one of the best pressure washers? Think again. This pressure washer from Worx makes cleaning outdoors much more accessible thanks to the portability features that make it a totally 'ingenious' buy, according to our reviewer.

In short, you can fill it up using a nearby bucket or water butt, and battery power eradicates the need to be dictated by a plug or cord length. Even better, you can actually use a draw hose and soda bottle with this washer, and take it wherever you need to clean up outdoors.

This is a lightweight, compact tool, and while it is perfect for smaller jobs (especially in larger gardens), it won't quite hit the mark if you need a heavy duty pressure washer for big patio cleaning jobs, for example. If you already own Worx products, you'll be happy to know that this tool is part of the Worx PowerShare system, so that you can use the battery across other garden tools. Our reviewer and garden expert Rhoda Parry found that the battery lasted for around 30 minutes of pressure washing, which is plenty enough for smaller jobs.

Not well equipped power-wise for big jobs

This versatile, compact pressure washer is not only budget-friendly, but also a total all-rounder. Ideal Home's Editor Heather Young has been testing the Karcher K2 out for some time now, saying that while it's 'small and compact, it doesn't compromise on power.' 

Heather loves using the K2 in her garden as part of a clean-up operation after gardening work - especially after wet weather. Her patio has been cleared of mud thanks to this pressure washer, and the compact nature of the K2 means it's a breeze to get out and pack away again, even for small jobs. Heather says that she's more inclined to use the K2 than her full-sized pressure washer, thanks to just how convenient it is. 

Pet owners can also trust the K2 to help them get rid of pesky muddy paw prints across the garden, as well as for smartening up their car or garden furniture. For portability, look no further than the built-in wheels, five-metre cable and extendable handle. 

 While this is a great value choice for smaller jobs and gardens, it has to be said that the K2 probably isn't the most capable choice for expansive patios or walls. For quick and easy use though, it's a total star.

Not great for cleaning dark coloured cars

The Stihl RE 120 Pressure Washer is an admittedly expensive buy, with a price tag of £420.00 (though you can find it elsewhere for less) but our expert reviewer Linda Clayton stands by the fact that it's a value-for-money buy if you can afford it. This ultra-capable pressure washer aced almost every test Linda threw at it - she's confident that it can transform any outdoor space. 

She used it across her home to bring various areas back to life, including her patio, slate slabs and steps, outdoor furniture, glass divider, and stone brick pathway. The user-friendliness of this pressure washer was one of Linda's highlights, with small details going a long way to make using the Stihl RE 120 more enjoyable. She was especially keen on the RA 90 Surface Cleaner attachment from the brand, which sparked her enthusiasm to clean almost every surface in her back garden. Of all the pressure washers she's tested, Linda also found that connecting and disconnecting this model was easier than the rest. 

The one test the STIHL RE 120 Pressure Washer fell down on was cleaning Linda's dark coloured car, with some smear marks being left over. This aside, the STIHL RE 120 Pressure Washer proved itself to be an unmissable pressure washer if you've got a long list of outdoor jobs to get on with, and a bigger budget.
