Abstract
A wet carpet cleaning apparatus having a nozzle movable over the surface to be cleaned. Structure is associated with the nozzle for selectively delivering cleaning liquid to a cleaning portion of the nozzle. A suction apparatus is removably mounted to the nozzle for removing liquid including dirt-laden water from the surface being cleaned. The suction apparatus comprises a removable suction fan or blower module which may be employed to advantage in a number of other applications. A jet pump is associated with the nozzle for discharging removed dirt-laden liquid as to a drain. The cleaning liquid is obtained from a pressurized water supply through an elongated flexible duct and the discharge to drain is through an elongated flexible duct which may be of similar construction. Manually controlled structure is provided for selectively introducing detergent into the cleaning liquid to permit selective cleaning and rinsing operations with the supplied pressurized water. The jet pump is operated by the pressurized water to effect the suction removal of the dirt-laden liquid from a collecting chamber in the nozzle to the drain duct. An auxiliary wand structure may be provided with a nozzle for cleaning elevated surfaces, such as furniture, steps, etc. An auxiliary scrubbing brush and an auxiliary squeegee may be mounted to the nozzle such as for cleaning hard floor surfaces.
