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. A latching mechanism can secure the cleaning head in an upright position, away from the floor, sufficiently to accommodate a tilting of the housing to an upright position in which a bottom of the housing (rather than the wheels) supports the device. A pair of pivot links, associated with each arm, limits pivoting of t…
