Like most lawn and garden equipment, pressure washers are available in both gas- and electric-powered versions, with each offering its own pros and cons. So, for example, if a pressure washer has a PSI of 2,000 and a GPM of 1.5, then it has 3,000 cleaning units. Even if the pressure washer you're looking at doesn't give a CU rating, the measurement is simple to calculate. CUĬU stands for 'cleaning units,' and it's the best overall measurement to take into consideration when you're trying to figure out the efficiency of a power washer. Like with PSI, GPMs typically correspond with a pressure washer's use case, with low GPMs of 0.5-2 being seen on light-duty power washers, 1-3 GPM on medium-duty and 2-4 GPM ratings on heavy-duty pressure washers. So, a higher GPM translates to a better-performing pressure washer. If it's pumping out more water, then you'll be able to cover a larger area more quickly. GPMĪfter PSI, the other big measurement to look out for when shopping for pressure washers is GPM or 'gallons per minute.' This is a calculation of how much water your pressure washer is using, rather than how strong your stream is. These will have PSIs of 2,800 or more (typically at least 3,000 PSI) and should only be used on surfaces that won't be damaged by such high pressure. Stripping paint, blasting oil spots off of your driveway - that sort of thing. Heavy Duty: These are your big boys, reserved for the toughest and dirtiest jobs. Medium Duty: Ranking between 1,900 and 2,788 PSI, these mid-range pressure washers are better suited to your bigger jobs around the house, like cleaning off your deck or siding. Light Duty: These washers max out below 1,900 PSI and are used in situations where too much pressure could cause damage, such as delicate areas of your home like gutters. Generally speaking, pressure washers are categorized into three groups based on their PSIs:

Basically, this tells you how powerful the stream is, and it will determine what kinds of jobs you'll be able to use your power washer for. PSI stands for 'pounds per square inch' and it's the pressure rating for your pressure washer.
