ABSTRACT:
A carpet cleaning apparatus consisting of a housing having a lower surface and an interior cavity. Wheels are secured adjacent to the lower surface of the housing. A conduit is secured to the housing. The conduit has a first end whereby the conduit may be coupled to a water supply and a second end with spray jets whereby fluids may be injected into a carpet. A discharge tank is secured within the interior cavity of the housing. The discharge tank has two suction ports, and two fluid inlets. Two suction conduits are provided. Each suction conduit has a first end communicating with one of the fluid inlets of the discharge tank and a second end disposed adjacent the lower surface of the housing. Two suction motors are secured in the interior cavity of the housing, each of the suction motors communicating with one of the suction inlets of the discharge tank such that a vacuum is created within the discharge tank and the suction conduits. Discharge fluids are drawn from the surface of a carpet via the suction conduits into the fluid inlets of the discharge tank.
