Abstract
A multi-use power foot suitable for use for both dry vacuum cleaning and water extraction procedures is disclosed. The power foot has a dry suction chamber in fluid communication with an outlet and a water suction chamber in fluid communication with the outlet. A diverter valve member is mounted within the housing to selectively restrict the air flow from one of the chambers to the outlet. A rotating brush is mounted in the opening of the dry suction chamber to agitate the surface to be cleaned in both the dry vacuum cleaning and water extraction modes. Spray nozzles are mounted to the underside of the power foot to direct a water based cleaning solution to the surface to be cleaned.
