Abstract

Agitating apparatus for a surface treating appliance includes a rotatable body having a plurality of grooves formed therein, an agitating member located within each groove so that at least one side edge of the agitating member protrudes outwardly from the body, and a connecting member located within each groove for connecting the agitating member to the body.

Claims (18)

1. An agitating apparatus for a surface treating appliance, comprising a rotatable body having a plurality of grooves formed therein, an agitating member located within each groove so that at least one side edge of the agitating member protrudes outwardly from the body, and a connecting member located within each groove for connecting the agitating member to the body, wherein each agitating member is in the form of a flexible strip of bristles, and the agitating member is clamped between the body and a respective connecting member along the length thereof.

2. The agitating apparatus of claim 1 , wherein the surface resistivity of each agitating member is in the range from 1×10 −5 to 1×10 12 Ω/sq.

3. The agitating apparatus of claim 1 , wherein each agitating member is formed from one of metallic, carbon fiber, conductive acrylic and composite material.

4. The agitating apparatus of claim 1 , wherein each groove is at least partially helical.

5. The agitating apparatus of claim 1 , wherein an outer surface of the connecting member is substantially flush with the outer surface of the body.

6. The agitating apparatus of claim 1 , wherein each agitating member is located within its respective groove so that opposing side edges of the agitating member protrude outwardly from the body.

7. The agitating apparatus of claim 1 , wherein each strip contains in the range from 20 to 100 bristles per mm length of the strip.

8. The agitating apparatus of claim 1 , wherein the bristles have a diameter in the range from 5 to 20 μm.

9. The agitating apparatus of claim 1 , wherein each strip has a thickness in the range from 0.25 to 2 mm.

10. The agitating apparatus of claim 1 , wherein the rotatable body comprises further surface agitating members.

11. The agitating apparatus of claim 10 , wherein the further surface agitating members are located between the grooves of the body.

12. The agitating apparatus of claim 10 , wherein the further agitating members are arranged in a plurality of rows along the body.

13. The agitating apparatus of claim 12 , wherein the rows of further agitating members are discontinuous.

14. The agitating apparatus of claim 10 , wherein the further surface agitating members comprise one of a plurality of bristles, a plurality of filaments, and at least one strip of material.

15. The agitating apparatus of claim 1 , in the form of a rotatable brush bar.

16. A cleaner head for a surface treating appliance comprising the agitating apparatus of claim 1 .

17. The agitating apparatus of claim 1 , wherein the connecting member is connected to the body.

18. The agitating apparatus of claim 1 , wherein the connecting member is located within each groove over the agitating member.
