Generac pressure washers are available from 2000psi to 3100psi and provide a powerful blast to clean virtually any surface. They can be used for cleaning cars, boats, recreational vehicles as well as sidewalks and driveways. The ONEWASH from Generac is essentially four pressure washers in one. Whatever the cleaning task the ONEWASH adjusts the pressure accordingly. Too much pressure can damage a surface and too little pressure will prevent it from getting the correct blast. The ONEWASH makes sure that the correct pressure is chosen for each surface type.
