A fluid distribution apparatus is provided which includes a sensor for developing control signals representative of the profile of a vehicle to be cleaned and a tube for distributing fluid. The tube is movable horizontally in directions parallel to the path of a vehicle being cleaned and vertically toward and away from the path of the vehicle. Movements of the tube are controlled to position the tube in front of the vehicle and move the tube in the direction of movement of the vehicle and to position the tube above the vehicle and move the tube in a direction opposite that of the vehicle and simultaneously move the tube vertically to follow the profile of the vehicle. The tube is also positioned behind the vehicle and moved in the direction of the vehicle after the profiling. Oscillatory movement of the tube about a plurality of angular positions is also provided.
