The invention is directed at systems and methods which provide for effective cleaning and drying of vehicles of different shapes and sizes. The invention in one example includes a vehicle washing apparatus comprising a conveyor system to move a vehicle along a path, and a bridge assembly supported above a vehicle and moveable along the length thereof. At least one trolley assembly is operatively supported by the bridge assembly and is moveable in a direction generally transverse to the movement of the bridge assembly. At least one cleaning arm assembly for delivering cleaning fluid to or for brushing the surface of a vehicle is operatively supported by the at least one trolley assembly or bridge. The cleaning arm assembly is moveable with the bridge assembly along the length of the vehicle, and transversely with the at least one trolley assembly to adjust the location of the cleaning arm relative to the vehicle, wherein the bridge assembly moves in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.
