Abstract

A carpet cleaning apparatus is disclosed with a loop agitator. The loop agitator comprises a spindle with a plurality of flexible loops attached to the spindle. A blade is provided in close relative proximity to the agitator for severing hair and other fibers that become entangled on the agitator.

Claims

1. A cleaning apparatus comprising

an agitator for agitating a material and disturbing debris in the material,

means for rotating said agitator,

means for supplying and directing a solution toward the agitator and further disperse the solution onto said material,

means for supplying suction to remove said solution and debris from the material,

wherein the agitator comprises a spindle adapted to rotate around a central axis and further comprising at least one helical row of a plurality of flexible loops attached thereto, wherein the loops of the at least one helical row are mounted at an angle to the direction of rotation of the spindle.

2. The cleaning apparatus of claim 1 wherein the spindle has at least two helical rows of a plurality of flexible loops attached thereto, a first row of loops is angled to the left of the direction of rotation and a second row of loops is angled to the right of the direction of rotation.

3. The cleaning apparatus of claim 1 wherein said loops comprise a synthetic fiber.

4. The cleaning apparatus of claim 1 wherein said loops are substantially elastic.

5. The cleaning apparatus of claim 1 wherein said loops are nylon.

6. The cleaning apparatus of claim 1 wherein said loops comprise a substantially solid inner portion.

7. The cleaning apparatus of claim 1 wherein the spindle has at least two helical rows of a plurality of flexible loops attached thereto, and the loops of the at least two helical rows are mounted at an angle to the direction of rotation.

8. The cleaning apparatus of claim 1 wherein the agitator has at least one squeegee element attached thereto.

9. The cleaning apparatus of claim 1 wherein the solution is water, or a mixture of water and cleaning chemicals.

10. The cleaning apparatus of claim 1 wherein a blade is mounted on the cleaning apparatus in relatively close proximity to the agitator, said blade being adapted to sever objects wound on the agitator.

11. The cleaning apparatus of claim 10 wherein the blade is ⅛

of an inch away from the loops on the agitator.

12. The cleaning apparatus of claim 10 wherein the blade comprises an edge, the edge being substantially parallel to the central axis of the spindle.

13. The cleaning apparatus of claim 10 wherein the blade has a serrated edge.

14. A cleaning apparatus comprising

an agitator for agitating a material and disturbing debris in the material,

means for rotating said agitator,

means for supplying and directing a solution toward the agitator and further disperse the solution onto said material,

means for supplying suction to remove said solution and debris from the material,

wherein the agitator comprises a spindle adapted to rotate around a central axis and further comprising at least one straight row of a plurality of flexible loops attached thereto, wherein the loops of the at least one straight row are mounted at an angle to the direction of rotation of the spindle.

15. The cleaning apparatus of claim 14 wherein said loops comprise a substantially solid inner portion.

16. The cleaning apparatus of claim 14 wherein the spindle has at least two straight rows of a plurality of flexible loops attached thereto, and the loops of the straight rows are mounted at an angle to the direction of rotation.

17. The cleaning apparatus of claim 14 wherein the agitator has at least one squeegee element attached thereto.

18. The cleaning apparatus of claim 14 wherein the spindle has at least two straight rows of a plurality of flexible loops attached thereto, a first row comprises loops angled to the left of the direction of rotation and a second row comprises loops angled to the right of the direction of rotation.

19. The cleaning apparatus of claim 14 wherein a blade is mounted on the cleaning apparatus in relatively close proximity to the agitator, said blade being adapted to sever objects wound on the agitator.

20. The cleaning apparatus of claim 14 wherein the blade comprises an edge, the edge being substantially parallel to the central axis of the spindle.
