The nozzle 10 may be vertically movable in the sub-frame to follow the contours in the vehicle, e.g. as described in Specification 1,100,583, and the movement of the brushes, and nozzles 9 may also be controlled in known manner, e.g. as described in Specifications 1,114,418, 1,141,947 and 1,185,331. The sub-frame 5 may be supported on wheels 8 in addition to the projections 26. For automatic operation a coin box 21 may be attached to the sub-frame.
