Abstract

A floor tool for a surface treating appliance, comprising a suction opening through which a dirt-bearing fluid flow enters the floor tool, and an agitating apparatus comprising a rotatable body having an outer surface which is substantially covered with filaments having a surface resistivity in the range from 1×10 −5 to 1×10 12 Ω/sq.

Claims

exact text as granted — not AI-modified
1 . A floor tool for a surface treating appliance, comprising a suction opening through which a dirt-bearing fluid flow enters the floor tool, and an agitating apparatus comprising a rotatable body having an outer surface which is substantially covered with filaments having a surface resistivity in the range from 1×10 −5  to 1×10 12  Ω/sq. 
     
     
         2 . The floor tool of  claim 1 , wherein the filaments are formed from one of metallic, carbon fibre, conductive acrylic and composite material. 
     
     
         3 . The floor tool of  claim 1 , wherein the filaments are woven on to a flexible carrier member located about the body. 
     
     
         4 . The floor tool of  claim 3 , wherein the carrier member is wound about the body. 
     
     
         5 . The floor tool of  claim 4 , wherein the carrier member is adhered to the body. 
     
     
         6 . The floor tool of  claim 1 , wherein the body is substantially cylindrical. 
     
     
         7 . The floor tool of  claim 1 , wherein the filaments have a diameter in the range from 5 to 20 μm. 
     
     
         8 . The floor tool of  claim 1 , wherein the filaments have a length in the range from 4 to 15 mm. 
     
     
         9 . The floor tool of  claim 1 , wherein tufts of relatively stiff bristles are dispersed within the pile. 
     
     
         10 . The floor tool of  claim 1 , in the form of a rotatable brush bar.
