Precision vacuum cleaner head

Abstract

A precision vacuum cleaner head is to be employed on a variety of vacuum cleaning units, the head being especially adaptable for use with portable, handheld vacuum cleaning units. The head has a tapered outer housing configured to enter and clean corners. The housing encloses a chamber which has two different sized rotary brush members, the smaller of which is located at the tapered end of the housing. Airflow suction from the vacuum cleaner provides a vacuum suction airflow in the housing. This airflow acts on a turbo drive wheel to rotate both brush members. The tapered housing permits efficient and effective cleaning of both flat surfaces and corners.

1 . A vacuum cleaner head comprising: 
 a tapered housing with a forward end section, an after end section, and an upper surface which is tapered from the forward end section downwardly to the after end section, said housing having a substantially enclosed chamber, and an extension section for connection to a line from a vacuum source;    first rotary brush means located within the chamber, for cleaning soiled surfaces;    second rotary brush means, being smaller than the first rotary brush means, for cleaning soiled surfaces, said second brush means being located within the chamber, in the tapered forward section of the housing; and    turbo means located within the chamber for rotatably driving the first and second rotary brush means.    
   
   
       2 . The vacuum cleaner head as in  claim 1  further comprising belt means extending between the turbo means and the first and second brush means for rotatably driving both said brush means.  
   
   
       3 . The vacuum cleaner head as in  claim 1  wherein the turbo means is driven by vacuum suction through the extension section of the housing.  
   
   
       4 . The vacuum cleaner head as in  claim 1  further comprising an opening in the housing through which the first and second rotary brush means clean soiled surfaces.  
   
   
       5 . The vacuum cleaner head as in  claim 1  wherein the first rotary brush means comprises a plurality of brush bristles and the second rotary brush means comprises a plurality of brush bristles which are smaller than the bristles of the first rotary brush means.  
   
   
       6 . The vacuum cleaner head as in  claim 1  further comprising adjustable means to control vacuum suction within the chamber.  
   
   
       7 . The vacuum cleaner head as in  claim 6  wherein the suction control means comprises a valve located on the housing.
