A Pressure Washer uses a high-pressure washing system to clean dirt, debris, and grime from hard surfaces. Pressure Washers check the water supply, maintain safe pressure washer handling practices, remove rubble from the work area, and ensure that the water pressure is appropriate for surface preparation, sidewalk cleaning, and building restoration. Pressure Washers also use high-pressure water jets to clean driveways and pools, usually for commercial clients. Although they most frequently do water cleaning, in some cases, Pressure Washers operate machines that contain chemicals to remove resistant debris.
