Any KC, KC-D, or even GVS Series floor machine may be used for shampooing rugs by simply adding a solution tank and fountain brush to any of these polishers. Solution is dispensed with hand control through the valve, plastic tube and is deposited on the back of the fountain brush. Solution tanks are molded polyethylene, seamless and spillproof (even if handle is horizontal on floor). No tools needed to attach. Tanks are available in 2 1/2 and 4 gallon sizes.
