Cleaner head for a vacuum cleaner

Abstract

A cleaner head for a vacuum cleaner that comprises a pair of rotary agitators and one or more wheels. The agitators rotate in opposite directions, and the wheels are moveable between a deployed position and a retracted position. The wheels contact a floor to be cleaned when in the deployed position, and the wheels are lifted clear of the floor when in the retracted position such that the cleaner head is supported on the floor solely by the agitators.

1 . A cleaner head for a vacuum cleaner, the cleaner head comprising a pair of rotary agitators and one or more wheels, wherein the agitators rotate in opposite directions, the wheels are moveable between a deployed position and a retracted position, the wheels contact a floor to be cleaned when in the deployed position, and the wheels are lifted clear of the floor when in the retracted position such that the cleaner head is supported on the floor solely by the agitators. 
     
     
         2 . The cleaner head of  claim 1 , wherein the agitators and the wheels rotate about axes of rotation that are parallel to one another. 
     
     
         3 . The cleaner head of  claim 1 , wherein the wheels comprise a pair of wheels located on opposite sides of the cleaner head at positions between the agitators. 
     
     
         4 . The cleaner head of  claim 1 , wherein the wheels are located midway between the agitators. 
     
     
         5 . The cleaner head of  claim 1 , wherein the cleaner head comprises a housing within which the agitators are rotatably mounted, and a neck pivotally attached to the top of housing at a position between the agitators. 
     
     
         6 . The cleaner head of  claim 5 , wherein the neck is pivotally attached to the top of the housing at a position midway between the agitators. 
     
     
         7 . The cleaner head of  claim 1 , wherein the agitators are identical and rotate at the same speed.
