Here’s an example:Įven though Model A didn’t have the highest PSI or GPM rating, it actually has the most overall cleaning power. One way to compare one pressure washer’s power to another is simply to multiply the two values together. Some models have a flow control valve on the pump if you want to reduce water flow. More water flow means more water is hitting the surface. GPM (gallons per minute) is a measure of the maximum water flow. You’ll get the most pressure from your 0º tip and it reduces (or disperses) as you move to your wider angle tips. Higher pressure means more cleaning force. PSI tells you the maximum force the water is going to hit your surface with. PSI, or pressure (pounds per square inch), is usually what gets the most attention, but they’re both important. PSI vs GPMĮvery pressure washer and power washer comes with two numbers: a PSI rating and a GPM rating. They’re also more expensive and require more maintenance, which is why many Pros and homeowners opt to use a pressure washer with a chemical detergent instead. That makes power washers better for cleaning stuck-on messes such as oils and greases. There’s one major difference, though-power washers have a heating element and pressure washers don’t. We find pressure washers and power washers to be very similar, and you’ll see them with similar PSI/GPM ratings. Pressure Washer Buying Guide Pressure Washer vs Power Washer: Aren’t They the Same?
