ABSTRACT:
A vehicle washing apparatus particularly adapted for use in closed bays comprising a stationary frame carrying a plurality of brushes to wash the vehicle as it moves through the unit in a forward direction and to rinse the vehicle as it backs out of the unit in the reverse direction. The brushes include two opposed warp-around brushes, a top brush, and two opposed ledge brushes. The warp-around brushes and the top brush are movable between an operative vehicle washing position during the forward movement of the vehicle and an inoperative retracted position during the reverse movement of the vehicle. The stationary frame carries detergent and rinse spray arches. A control circuit is provided to automatically control operation of the brushes, the detergent arch and the rinse arch pursuant to the passage of a vehicle through the unit.
