Cleaning Efficiency – Higher GPM means more water volume, which helps rinse away dirt and debris faster.
Surface Coverage – A higher GPM allows you to clean larger areas more quickly.
Chemical Application – When using soft washing techniques, GPM affects how well chemicals are applied and rinsed.
Pairing with PSI – While PSI (Pounds per Square Inch) determines water pressure, GPM determines how much water is delivered. Together, they dictate overall cleaning power.
