ABSTRACT:
A "roll over" type vehicle wash apparatus includes a frame which is movable on a track and which is driven between a front end and a rear end of the track. The apparatus includes a pair of front arms and a pair of rear arms which are pivotally connected to the frame. Side wrap brushes are rotatably connected to each of the front and rear arms and are rotated about vertical axes. Positioned proximate the rear end of the track are arm deflectors which cause the rear arms to be driven inward toward one another as the frame approaches the rear end. This prevents the rear arms of the apparatus from being accidentally driven through doors at the ends of the bay area in the event of a failure of the actuators of the rear arms.
