Karcher were the first to introduce smart technology to pressure washers so you can connect them to your smartphone via an app. Although you have to be near a power outlet to use an electric washer, they are typically lighter, better for the environment, less noisy and will be powerful enough for the usual home and garden cleaning jobs. Medium duty pressure washers tend to be a mix of high-end own-brand models and cheaper premium-brand models. As such, you'll find a confusing array of high-powered-but-basic models by garden machinery brands such as Stihl or Nilfisk, mid-powered Karcher, Bosch or Vax models with some choice of accessories, and high-powered and highly accessorised machines from Qualcast and Mac Allister. If you just need a pressure washer for light cleaning, then most no-frills machines come with just one lance, which is a long tube with a nozzle on the end. The nozzle will usually provide variable pressure – when you twist the nozzle, you can adjust the spray from a powerful narrow jet to a more broad gentle fan.

The Mac Allister 1,800W is a cheap and powerful pressure washer with only a few flaws

The first thing you need to consider when investing in a pressure washer is which area or outdoor items you’re looking to clean. This will determine how much pressure – measured in bars – you need your washer to have. Our in-house experts at the GHI assessed the pressure washers' performance on common outdoor cleaning tasks, using their high-power jet sprays to take on muddy patios, windows and cars. The testers noted how easy the pressure washer was to set up, use, manoeuvre and, of course, the time it took to get the job done. The most powerful models cost hundreds of pounds so to avoid your pressure washer breaking, take a look at how to avoid issues, such as leaking and pump failure.

Fewer owners of Karcher pressure washers experienced faults within the first seven years of owning it - 8% said they had (sample size: 2,271) versus 16% of Nilfisk owners (sample size: 185). In terms of brand loyalty and how many people bought the same brand of pressure washer again, an impressive 73% of Karcher owners (sample size: 329) said they had versus 10% of Nilfisk owners (sample size: 52). Having recently cleaned my patio while testing the Kärcher K4 Full Control, I decided to put the Mac Allister through its paces by cleaning my car, my wheelie bin and my conservatory roof. Buying a new pressure washer can be confusing. There are usually several models in each manufacturer's range, with different types of motors and impenetrable model numbers which mean that useful accessories are either included in the price, or have to be bought as an extra. Nilfisk pressure washers tend to be quieter than Karcher models as they're designed with a noise-reduction system.To be fair, that problem isn’t exclusive to this particular pressure washer, but at least with the Mac Allister 2,100W you get a built-in cable winder to help keep things tidy.

Thanks to their concentrated water jets, pressure washers will save you valuable hours on the most heavy-duty tasks, as well as being incredibly satisfying to use on dirt and grime. Basic machines come with one lance – a long tube with a nozzle at the end. A fixed lance can’t be adjusted, though you can move it nearer or further away from the area you’re trying to clean. You can also buy models with a variable pressure lance, where you can twist the nozzle at the end to alter the power of the spray – rather like a hosepipe attachment. This lets you create either a powerful narrow jet of water or a gentler, broad spray. The shorter hose and low power can make cleaning slow and difficult, and the motors tend to be noisy. The parts also tend to be flimsy and prone to frost damage. Medium duty Pressure washer pump fails - Store the pressure washer in a frost-free place, such as a cupboard in the house, and make sure that the water is turned on and at adequate pressure before running the pump.

Light duty Hoses lengths vary from three metres, which is too short to wash a car; to five metres, which is an adequate length for car cleaning. Some of the cheaper pressure washers come with fixed nozzles that don't allow you to vary the water pressure.
