Abstract: A method of washing a vehicle is described which can accommodate vehicles having a wide variety of different lengths and does not require a motorized system to move the vehicle through the vehicle washing apparatus. The method includes the steps of moving a movable washing member around four sides of the vehicle by moving the washing member 360 degrees on a continuous track and the track moves longitudinally on a plurality of fixed rails, washing the vehicle with the movable washing member, and sensing a vehicle position and length and controlling motion of the track on the fixed rails based on the sensed vehicle position and length.

Abstract: A vehicle washing apparatus is described which can accommodate vehicles having a wide variety of different lengths and does not require a motorized system to move the vehicle through the vehicle washing apparatus. The vehicle washing apparatus includes a movable washing member mounted for movement in a continuous path around a track. The entire track with the washing member mounted on the track is movable in a longitudinal direction along the length of a vehicle to accommodate vehicles of different lengths. According to one preferred embodiment, the longitudinal movement of the track and the washing member are controlled based on a sensed length of the vehicle.
