A downwardly open roller supported housing is provided, on its upper surface, with a handle equipped rearwardly and upwardly inclined casing. Transverse partitions, within the housing, form an air flow passageway open to the bottom of the housing and a liquid receiving chamber for used cleaning fluid. A nozzle, mounted in the housing, is connected by tubing with a source of cleaning fluid supply through a heater and detergent applicator for spraying the surface to be cleaned. A pump, supported by a housing partition, drains the used cleaning fluid chamber to a point of discharge by tubing extending through the casing. A blower, supported by a housing partition, induces air flow through the passageway for removing used cleaning fluid from the surface being cleaned.

Surface cleaning apparatus

A surface cleaning apparatus having a molded plastic housing and an upwardly and rearwardly projecting casing terminating at a handle. The lower portion of the housing includes a forward suction nozzle with an opening into a recovery tank and a molded plastic cover hingedly mounted over the recovery tank. The cover includes a downwardly projecting baffle adjacent the suction nozzle opening into the recovery tank. Suction is generated by a blower at the rear of the recovery chamber and a shield positioned in front of the blower prevents liquid flow from the recovery chamber into the blower. The cover includes a raised portion extending out over the top of the shield and downwardly to a juncture with the forward baffle, the raised portion thereby defining a passageway around and over the shield whereby air is free to flow from the recovery chamber over the shield and into the blower. Liquid in the recovery chamber is pumped out through one compartment of a dual-compartment hose which empties into a remote drain. The other compartment of the dual-compartment hose is connected to a faucet such that clean water is fed to a set of spray nozzles located in the apparatus just behind the suction nozzle. The upwardly projecting control casing includes a well molded thereinto into which a solution bottle can be inverted and joined by a syphon line to the clean water line whereby the detergent solution can be introduced into the cleaning fluid as it is sprayed onto a carpet to be cleaned.
