How to buy the best pressure washer

Cable length

How long are the hose and power cable? Can you reach the top of the car or end of the driveway without having to unplug and rejig?

Pressure

How high is the pressure? For blasting mud off bikes or algae off garden furniture, a compact model with around 100 bar pressure is ample. Cleaning patios and gutters needs a good mid-range model, but for ingrained dirt, you might need a washer offering around 120 bar of pressure.

Weight

How heavy is the model? Most come with wheels, but even so you need to be conscious that you may need to lift it. Higher-powered equipment will often weigh more so choose carefully and don't over-specify if you don't need the pressure.

How to choose the best pressure washer?

When it comes to picking the most suitable product for your needs, it comes down to more than just price. While we all love a bargain, you often get what you pay for and splashing out just a little extra can mean you get a washer that will last longer and do the job better.

Pressure

Take a look at the pressure to see if the pressure washer will tackle the tasks you need it to with ease. A smaller model with around 100 bar pressure should be fine for cleaning mud off bikes or bits of moss and dirt off garden tables and chairs. For patios and guttering you want more of a mid-range model while for ground-in dirt, go for something around the 120 bar pressure mark.

Cable size

Check how long the lead is, as well as the length of any hose or attachments in order to make sure it will do the tasks you want it to. Does it need to reach high up to tackle the roof of the car for instance? Is it easier to have something that can reach round the side of the house to clean the front path or drive without having to unplug and re-start? By knowing what you want your pressure washer to do, this will help you determine the right length of cable and hose that you need.

Design

Have a look at the body of the pressure washer – does it look or feel cheap or is it more robust? Do the attachments look durable enough? If it comes with a range of add-ons, do you really need them or are you paying for things you won’t use on a regular basis? A good design is simple to put together, easy to use and hardwearing enough to cope with all weather conditions.
