ABSTRACT:
A wheel washer has first and second applicators which each have a row of plural spaced nozzles for delivering high pressure fluid to the wheels of a vehicle. The first applicator is fixedly mounted adjacent a track which guides the tires at the driver side of the vehicle. The second applicator is mounted by parallelogram support structure for movement toward and away from the tires at the passenger side of the vehicle. This second applicator is shifted to maintain a desired spacing between the nozzles and the wheels being cleaned, regardless of the width of the vehicle. Cleaning fluid is delivered to one nozzle of each applicator and a laterally disposed nozzle of the other applicator at a time. In succession, the pairs of nozzles apply cleaning fluid to the wheels as the vehicle travels through the vehicle wash. Treadle switches, angled relative to the direction of vehicle travel, are utilized to control the flow of fluid to the desired nozzles of the applicators.
