The control means comprise a control console Q which controls the washing unit AL and an electric control circuit (not shown) connected to the console Q which circuit controls the drying unit AA. As shown, the washing unit AL is a portal structure with a pair of adjustably spaced vertical rotary brushes 25 and a vertically movable upper horizontal brush 26 and the drying unit AA is a portal structure with opposite inwardly facing drying air outlet slots 13 and a vertically adjustable downwardly facing horizontal air outlet slot 14. In operation, the units AA, AL start their forward movements in the direction of arrows 29, 28 from the same end of the track B with the drying unit AA in advance of the washing unit AL but with the drying unit AA inoperative while the washing unit AL washes the vehicle body V. The return movement in the direction of arrow 31 is accomplished with the washing unit AL rinsing the vehicle body V in advance by a constant distance of the now operative drying unit AA which dries the vehicle body V, the air outlet slot 14 moving vertically to follow the profile of the upper surface of the body V as the drying unit AA moves by means of an electro mechanical feeler 18. The units AA, AL have respective propelling motors and in the forward movement of the drying unit AA its motor may be inoperative with the drying unit AA pushed by the washing unit AL. In an alternative mode of operation, the washing unit AL starts its forward movement from the opposite end of the track B to the drying unit AA and the drying unit AA only makes one movement in the direction of arrow 31 behind the washing unit AL as it makes its return movement.
