Abstract: A mobile vehicle washing apparatus in which the length, width and height of the apparatus may each be adjusted to the size of the vehicle to be washed and for easier transport. The frame dimensions may be adjusted by a system of cranks found on each frame member that may need to be adjusted. Also, attached to the frame are swinging arm members that may clean the bottom side of a vehicle passing through them. Powered brush members are used in the apparatus as a means to scrub vehicle surfaces. The cleaning and rinsing fluids pass through a series of hoses and nozzles mounted about the frame so that the tops and left and right sides of the vehicles being cleaned may be covered by said fluids.
