Whether it's for cleaning your garden, driveway, car or patio, we round up the five top-scoring pressure washers to help you find the best one for the job.

Buying a new pressure washer can be very 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 extra.

To help you find the best pressure washer for your needs, we've rounded up the top-scoring models in five different categories, as well as some less impressive models that we think are best to avoid. 

And because they've all gone through rigorous Which? lab testing, you can rest assured that no matter which of these Best Buy pressure washers you go for, they will tackle your tough outdoor tasks.

Pressure washers to avoid

The only way to tell if a pressure washer is any good is to clean a range of different surfaces with it, which is why Which? does exactly that in our independent lab tests. We use each power washer on squares of concrete, paving slabs, block paving, decking, stone wall and some rather filthy cars to find out how well they clean.

Not all pressure washers are great, here are two models that could leave you feeling underwhelmed.

    It's not terrible, but it's overall this pressure washer is an underwhelming performer. It doesn't have enough power to clean quickly, plus it's heavy and awkward to use. Overall, you should consider a different model.

    This is one of the cheaper full-sized pressure washers in this well-known manufacturer's range. However, even as a 'cheap' model it's still expensive, especially for a machine that can't tackle heavy dirt and grime.
