ABSTRACT:
A water/cleaning solution vacuum carpet cleaning apparatus includes a carpet cleaning wand having a carpet contacting end region, a source of pressurized water and a source of pressurized carpet cleaning solution. Piping and controls are included for selectively providing pressurized water and cleaning solution to the carpet contacting end region of the wand. Included is a dirty liquid-air separation vessel having an outer shell, an air tube coaxially installed in the shell and a dirty liquid tube installed in the shell and extending around portions of air discharge tube in a spaced apart relationship so as to form a first, inner annular space therebetween. A second, outer annular space is defined between the shell and the dirty liquid tube, a lower end of which is spaced above the bottom of the shell. A dirty liquid and air suction pipe extends through the shell and into upper regions of the inner annular space. A dirty liquid discharge conduit is connected through the shell and into the second annular space above the lower end of the shell so that accumulated dirty liquid in the bottom of the vessel seals off lower regions of the dirty liquid tube, thereby reducing its volume and increasing efficiency of the apparatus. A flexible fluid conduit is connected between the wand and an inlet end of the air and dirty liquid tube at the separation vessel, vacuum applied to the air tube causing suctioning of the air and dirty liquid from the wand into the vessel for separation therein. Upper regions of the first and second annular spaces are interconnected and a regulator controls the pressure differential between the two annular spaces.
