Abstract
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.
