ABSTRACT OF THE DISCLOSURE In a car wash apparatus for automatically scrubbing, washing and polishing the sides, rocker panels and wheels of a vehicle during movement along a predetermined path upon a floor, there is provided a pair of laterally spaced free standing longitudinally staggered scrubbing side wheel assemblies. Each assembly includes a base plate upon the floor and mounting an upright side frame. Parallel spaced first and second side wheel arms at their one ends are pivotally mounted upon the frame and extend forwardly at an acute angle toward the path of movement. Each arm at its free end mounts a bearing housing which supports the hydraulic motor whose drive shaft is journaled through the bearing housing and mounts upon a vertical axis, a scrubbing, washing and polishing wheel of cloth material. The side arms are interconnected for movement in unison. A pneumatic-hydraulic circuit is provided including an actuating cylinder located between the frame and the side wheel arm of one of the side wheel assemblies for moving the wheel arms and connected scrubbing wheels relative to the predetermined path and to the vehicle. A normally open three- way valve is located in a branch conduit of the circuit for delivering air to a pilot operated check valve located in the hydraulic conduit connecting the rod end of the cylinder to the corresponding air over oil reservoir.
