Abstract

An accessory tool for use with a suction source has a housing with a suction outlet and a fluid inlet. The suction outlet is adapted to be connected to the suction source. A roller assembly has a roller element rotatably mounted in the housing and adapted to contact a surface being cleaned. A turbine assembly has a turbine housing and a turbine fan rotatably mounted within the turbine housing. The turbine housing includes one or more inlet apertures in fluid communication with the atmosphere, as well as a turbine outlet in fluid communication with the suction outlet. A drive mechanism is operably coupled to both the turbine fan and to the roller element to drive rotation of the roller element when the suction source is connected to the suction outlet.

1 . A hand-held accessory tool for use with a suction source and a fluid source comprising:
 a main housing comprising a suction outlet and a fluid inlet, wherein the suction outlet is adapted to be operably coupled to the suction source, and the fluid inlet is adapted to be fluidly coupled to a fluid source;   a roller element rotatably mounted in the main housing and adapted to contact a surface being cleaned, the roller element comprising a soft, compressible, and absorbable cleaning medium;   a turbine assembly associated with the main housing and comprising a turbine housing and a turbine fan rotatably mounted within the turbine housing, the turbine housing including at least one inlet aperture in fluid communication with the atmosphere, and further including a turbine outlet in fluid communication with the suction outlet; and   a drive mechanism operably coupled to both the turbine fan and to the roller element and adapted rotate the roller element;   wherein the turbine fan is adapted to rotate when suction is applied to the suction outlet, and the rotation of the turbine fan drives rotation of the roller element through the drive mechanism.   
     
     
         2 . The hand-held accessory tool of  claim 1  and further comprising a fluid distributor that is connected to the fluid inlet and is adapted to apply fluid to the roller element when the fluid distributor is connected to a fluid source 
     
     
         3 . The hand-held accessory tool of  claim 2  wherein the fluid distributor comprises a spray tip. 
     
     
         4 . The hand-held accessory tool of  claim 2  and further comprising a suction nozzle mounted within the housing and defining a nozzle inlet and a nozzle outlet, the nozzle inlet is positioned adjacent the roller element and the nozzle outlet is fluidly connected to the suction outlet, wherein suction nozzle is adapted to remove fluid and debris from the roller element when the suction outlet is fluidly connected to a suction source. 
     
     
         5 . The hand-held accessory tool of  claim 4  wherein the drive mechanism is adapted to rotate the roller element in a direction so that the nozzle inlet is circumferentially spaced in the direction of rotation of the roller element downstream from the fluid distributor so as to remove the portion of fluid and debris from the roller element after the roller element has been wetted. 
     
     
         6 . The hand-held accessory tool of  claim 1  and further comprising a suction nozzle mounted within the housing and defining a nozzle inlet and a nozzle outlet, the nozzle inlet is positioned adjacent the roller element and the nozzle outlet is fluidly connected to the suction outlet, wherein suction nozzle is adapted to remove fluid and debris from the roller element when the suction outlet is fluidly connected to a suction source.
