Pounds per square inch. A unit of measurement referring to the pressure exerted on one square inch of an object’s surface. In the case of pressure washers, the measurement of the strength of the spray coming out of the nozzle. A typical garden hose releases water at a pressure of about 40 PSI, a light-duty electric washer runs about 1000 to 1200 PSI and a heavier-duty consumer-grade gas model operates from about 2800 to 3500 PSI. Industrial-strength washers can exceed 5000 PSI.
