Pressure washers clean surfaces by applying a powerful stream of pressurized water. First, you’ll need to understand the measurement terms used when describing pressure washers. Pounds per square inch (PSI) is the way water pressure is measured. The higher the PSI, the more power the pressure washer will have. Gallons per minute (GPM) describes the amount of water hitting the surface you are cleaning. A pressure washer with a higher GPM will take less time to clean surfaces than a model with a lower GPM. Power washers are usually categorized by their GPM, PSI and their power source whether they are gas or electric.
