ABSTRACT:
A device for washing automobiles, vans, and other vehicles is shown which comprises a movable spray bar with high velocity spray nozzles mounted thereon, as well as associated supporting structure, and motion inducing means. In the washing process, the lateral profile of the vehicle is tracked by an array of photoelectric cell detectors mounted on the spray bar. Based on electronic output signals from the detectors, which are processed by a preprogrammed logic control unit and relayed to the motion inducing means, the spray bar is maintained at a predetermined height above, and the nozzles at a constant angle to, the vehicle surfaces being washed.
