ABSTRACT:
A pressure washer sprays a pressurized liquid into a groove of a pavement, floor or similar surface to remove dirt and debris from the groove. The dirt and debris dissolves and/or becomes suspended in the liquid and is then removed from the pressure washer for disposal. The pressure washer includes a cleaning hood with a cover plate and a skirt that extends downward from the periphery of the cover plate to form a less than air tight seal with the surface containing the groove. A spray nozzle in a forward portion of the cover plate directs the pressurized liquid spray downward into the groove, where the liquid picks up dirt and debris to form a liquid suspension and/or solution, and preferably, rearward toward an exhaust port which removes the liquid suspension and/or solution of dirt and debris from the cleaning hood. A handle extends upward from the cleaning hood for guiding the pressure washer. The handle also carries a pressurized liquid supply line connected to the spray nozzle and a vacuum line connected to the exhaust port.
