Abstract: A portable, compact and self-contained continuous flow recycling system includes a housing to accommodate a vacuum motor and liquid pump for recirculating a liquid cleaning solution and air. A pair of wheels supports the housing for tilting about a wheel axle. A pair of support arms are mounted to rotate on the axle, and their opposite ends are fixed to the shell of a cleaning head. The head is shaped to define a first compartment for receiving atomized cleaning solution and air, and a second compartment. A vacuum source draws the solution and air from the first chamber, across a partition near the floor, into the second compartment. The head is free to travel in an arcuate path relative to the housing, with its orientation determined by the arms, to insure a desired coplanarity with the floor or other surface being cleaned, when the head is in its operating position.

Abstract: The invention provides a cushioning control circuit which restricts the initial flow of current to a D.C. permanent magnet motor by providing a neon control lamp in series with a pair of triac control circuits which drops the initial voltage imposed on the motor windings.
