Apparatus is provided which enables an operator to wash vehicles of various shapes, sizes and configurations efficiently and thoroughly. A pair of spaced longitudinally extending rails is suspended along either side of a vehicle washing station. A carriage beam extends transversely between the rails and is mounted for back and forth movement longitudinally therealong. A traversing carriage is mounted upon the carriage beam, and a travelling scaffold is suspended from the traversing carriage for movement therewith. A washing unit is mounted upon the travelling scaffold for movement up and down therealong. The washing unit includes a cantilevered boom upon which spray nozzles are mounted for discharging selected washing fluids under high pressure. The boom is pivotable upwardly and downwardly in a vertical plane, and is rotatable about its longitudinal axis. The nozzles are mounted upon the boom for oscillating pivoting movement. An operators platform is provided for movement around the vehicle with the washing unit as washing proceeds.
