Rotating brush attachment for use with a vacuum

Abstract

A motorized vacuum brush head for use with a vacuum. The brush head has a body with an air passage passing though it. The face of the brush head faces the surface being cleaned. A rotatable brush and the air passage mouth are on the face. The brush is flat and has an axis of rotation substantially perpendicular to the face. The brush rotates parallel to and substantially co-planar with the face. Several arms of bristles extend radially from the brush's axis of rotation. As the brush rotates, the leading edge of the bristles drive debris toward the mouth, where it becomes entrained in the air stream entering the vacuum. The rotation of the brush in the plane of the face allows the bristles to remain in continuous contact with the surface being cleaned, thereby increasing the efficiency with which the brush head, and by extension, the vacuum clean.

1 . A motorized vacuum brush head for use with a hand-held vacuum having an air intake aperture and an electrical system wherein said brush head comprises: 
 a body having a face;    an air passage extending through said body, said air passage having a mouth and a discharge opening, wherein said mouth is positioned on said face of said body and wherein said discharge end is configured to engage said air intake aperture of said hand-held vacuum;    a motorized brush positioned on said face of said body; said a motorized brush having an axis of rotation about which said brush is configured to rotate, said axis of rotation substantially perpendicular to said face whereby said brush is configured to rotate in a plane substantially parallel to said face;    an electric motor configured to drive said brush; and    an electrical connection between said brush and said electrical system of said hand-held vacuum.    
   
   
       2 . A motorized vacuum brush head according to  claim 1  wherein said brush is configured to rotate in a plane substantially co-planar with said face.  
   
   
       3 . A motorized vacuum brush head according to  claim 1  wherein said brush is positioned proximate to said mouth of said air passage.  
   
   
       4 . A motorized vacuum brush head according to  claim 3  wherein said brush is provided with bristles.  
   
   
       5 . A motorized vacuum brush head according to  claim 4  wherein said bristles are configured in a plurality of arms radiating outward from said axis of rotation.  
   
   
       6 . A motorized vacuum brush head according to  claim 5  wherein said arms of bristles are curved.  
   
   
       7 . A motorized vacuum brush head according to  claim 6  wherein said arms have a leading edge and a trailing edge when brush is rotated.  
   
   
       8 . A motorized vacuum brush head according to  claim 6  wherein said arms are configured to drive debris toward said mouth of said air passage when said brush is rotated.  
   
   
       9 . A motorized vacuum brush head according to  claim 3  wherein said brush is configured to engage an environmental surface during operation and wherein said brush is configured to maintain contact between substantially all of said bristles and said environmental surface during rotation of said brush.
