Abstract
A manually-operated trailer wash apparatus for washing an interior of a trailer includes a frame with a handle configured to be manually pushed by a human operator and front and rear wheels. Rotatable couplings are disposed between each of the wheels and the frame to rotate the wheels in response to the manual pushing of the handle. A conduit is coupled to the frame and extends transversely across a direction of travel of the apparatus. The conduit has a plurality of nozzles to pressure wash a surface on which the apparatus travels. The conduit receives pressurized fluid from a hose and pump system.
