A cleaner head for a cleaning appliance

Abstract

A cleaner head for a cleaning appliance including an agitator rotatable about an axis; a housing having a front side, a rear side, and first and second sides which extend between the front side and rear side, said housing further including a floor facing surface. The housing defines a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. A wiper device which extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. A floor engaging device extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. The floor engaging device includes an absorbent portion. The wiper device and the floor engaging device are positioned rearwardly of the dirty air inlet.

         2 . A cleaner head according to  claim 1  wherein the floor engaging device is positioned between the wiper device and the rear side of the housing. 
     
     
         3 . A cleaner head according to  claim 1  wherein the wiper device is positioned between the floor engaging device and the rear side of the housing. 
     
     
         4 . A cleaner head according to  claim 1  wherein the wiper device is positioned on a portion of a bottom of the housing that at least partially defines the chamber facing towards the surface to be cleaned. 
     
     
         5 . A cleaner head according to  claim 1  wherein the wiper device is pivotably moveable about an axis parallel to the agitator axis. 
     
     
         6 . A cleaner head according to  claim 1  wherein a length of the wiper device measured substantially parallel to the axis of the agitator is the same or greater than a length of the agitator measured along its axis. 
     
     
         7 . A cleaner head according to  claim 1  wherein the wiper device includes first and second lateral ends, and the agitator includes first and second lateral ends, wherein the first and second lateral ends of the wiper device are closer, respectively, to the first and second sides of the housing than the first and second lateral ends of the agitator. 
     
     
         8 . A cleaner head according to  claim 1  wherein a length of the floor engaging device measured substantially parallel to the axis of the agitator is greater than a length of the wiper device measured substantially parallel to the axis of the agitator. 
     
     
         9 . A cleaner head according to  claim 1  wherein the floor engaging device includes first and second lateral ends, and the wiper device includes first and second lateral ends, wherein the first and second lateral ends of the floor engaging device are closer, respectively, to the first and second sides of the housing than the first and second lateral ends of the wiper device. 
     
     
         10 . A cleaner head according to  claim 1  wherein the absorbent portion of the floor engaging device includes a lint pick-up strip. 
     
     
         11 . A cleaner head according to  claim 1  wherein the absorbent portion of the floor engaging device includes a felt material. 
     
     
         12 . A cleaner head according to  claim 1  wherein the absorbent portion of the floor engaging device includes a microfibre material. 
     
     
         13 . A cleaner head according to  claim 1  wherein the floor engaging device is held in a channel formed in the floor facing surface of the housing and is slidably removable therefrom. 
     
     
         14 . A cleaning appliance including a cleaner head according to  claim 1 .
