ABSTRACT:
A high-pressure surface-washing device has a frame (6) with adjustable-height wheels (17), a spray nozzle (15, 16 and 74) on at least one rotary spray arm (10, 11, 63 and 64) on a rotary axle (9 and 47) positioned on a bottom surface of the frame (6), a fluid conveyance in the rotary axle, a pressure-control valve (4) on a handle (5) attached to the frame (6), a high-pressure fluid conveyance (7) in communication between the pressure control valve and the fluid conveyance (20 and 62) in the rotary axle, a source of fluid (2) under select pressure, and a high-pressure fluid conveyance (3) in communication between the source of fluid under select pressure and the pressure control valve. The spray nozzle on the rotary spray arm is directed downwardly at an impingement angle in relation to rotational axis of the rotary spray arm. The rotary spray arm is caused to rotate and to achieve rotational cleaning in a rotational direction opposite from the impingement angle as a result of reactionary and ground effects of fluid escaping under pressure from the spray nozzle.
