Abstract: Vacuum cleaning apparatus has a hollow body providing a path of flow for air from a suction inlet to an outlet. An agitator, which is at the vicinity of the suction inlet and driven by an electric motor, has its opposite ends journaled in bearings which are vertically movable on the hollow body and biased downward to urge the agitator against a surface being cleaned.

Abstract: In surface treating apparatus having rotatable treating members movable over a surface, a container for liquid wax which is positioned in a compartment and has an outlet at its bottom normally closed by a valve having a vertically movable stem. A quantity of liquid wax is dispensed from the container each time the valve is moved upward from its closed position and returned thereto. The container is prevented from moving upward in its compartment when the valve is moved from its closed position by an upward force applied to the valve stem.
