(1) A wall cleaning unit including a housing with an open side for placement in contiguous relationship to a wall, upper and lower spray bars in the housing for directing high pressure water against the wall, sealing members on the housing around the opening for effecting sealing relationship with the wall, an outlet on the housing for conducting liquid away from the housing, and a high pressure liquid jet arrangement for creating a venturi effect to produce a suction for pressing sealing members against the wall. (2) A system for washing vertical walls including a vehicle mounted for movement along the top of the wall, a boom on the vehicle, a reel on the boom for moving a spray housing vertically on the wall, a source of high pressure water, a second reel on the boom for mounting a hose conducting high pressure water to the spray housing, and a motor on the vehicle for selectively moving the boom to cause the spray housing to move toward and away from the wall. (3) A vehicle for raising and lowering a spray housing including a frame, wheels on the frame for moving the frame in a first direction, a boom mounted on the frame for movement in a direction which is transverse to the direction of movement of the vehicle for moving a spray housing toward and away from a vertical wall, and a reel on the boom for mounting a cable for attachment to the spray housing.
