These brilliant tools shoot a powerful jet of water that makes them ideal for cleaning everything from filthy cars to dirty patios.

Types of pressure washer

Electric pressure washers

Electric pressure washers are perfect if you just want something that will deal easily with average jobs around the home and garden. They run off mains electricity, are quiet and easy to use, and affordable to buy.

Petrol pressure washers

Petrol powered pressure washers are a lot more powerful than electric ones and more expensive to buy, making them more appropriate for heavy duty uses. However, as they’re powered by fuel rather than connected to mains electricity they don’t have any trailing cables meaning you’re free to take them anywhere.

Which one is right for you?

A simple rule is to have a think about all the jobs you might need a pressure washer for and then buy the best one you can afford. Here’s a few things to help you decide which sort of washer is right for you.

• A washer with adjustable pressure settings will give you much more flexibility over the sort of jobs you can use it for.

• Water flow is as important as water pressure. Make sure you choose a washer with generous flow – the average is around 400 litres per hour.

• If space is an issue, look for upright models that take up less room, and those with built-in storage to keep cables and hoses safely tucked away.

• Look for models with an auto stop/start function – this will reduce the amount of water you use and prolong the life of your washer.

• More powerful pressure washers are heavier, so look for models with wheels and a handle to help you move it around.

Using your pressure washer

Pressure washers are connected to either a mains water supply or a tank, and are incredibly efficient when compared to a regular garden hose – they can use as little as 400 litres of water an hour and still give you 100 bar pressure, while a standard hosepipe would use around 3500 litres but only manage 4 bar. If you’re connecting your washer to a tank, you’ll want to use a filter to prevent any sediment getting into the machine, and don’t let the water completely run out as this could damage the motor.

Pressure washers can be used for a wide variety of cleaning jobs. This quick guide will give you an idea of the sort of pressure you’ll need for some of the most common tasks.
