Abstract

A method of removing hair from a surface laden with hair comprising moving a hair collection element along the surface in a first direction to collect hair, depositing the collected hair at a first location, gliding the hair collection element along the surface in a second direction away from the first location and removing the collection hair from the first location.

Claims (23)

1. A method of removing hair from a surface laden with hair, comprising:

moving a hair collection element along the surface in a first direction to collect hair;

depositing the collected hair at a first location;

gliding the hair collection element along the surface in a second direction away from the first location; and

removing the collected hair from the first location by suctioning the collected hair;

wherein the moving step comprises applying pressure to the surface using the hair removal element and the gliding step comprises relieving pressure applied by the hair collection element on the surface so that collection of hair in the second direction is substantially avoided.

2. The method of removing hair of claim 1 wherein the depositing step comprises forming a pile of the collected hair at the first location.

3. The method of removing hair of claim 2 wherein the hair collection element comprises a plurality of projections that are transversely elongated.

4. The method of removing hair of claim 3 wherein the projections are arranged in a plurality of rows and the projections in one row are offset from elongated projections in an adjacent row.

5. The method of removing hair of claim 4 wherein the hair collection element is formed of an elastomeric material.

6. The method of removing hair of claim 5 wherein the moving step comprises moving a vacuum cleaner in the first direction.

7. The method of removing hair of claim 6 wherein the gliding step comprises moving the vacuum cleaner in the second direction.

8. A method of removing hair from a surface laden with hair, comprising:

moving a hair collection element along the surface in a first direction to collect hair;

depositing the collected hair at a first location;

gliding the hair collection element along the surface in a second direction away from the first location; and

removing the collected hair from the first location by suctioning the collected hair;

wherein the hair collection element comprises a directional fabric.

9. The method of removing hair of claim 8 wherein the moving step comprises moving a vacuum cleaner in the first direction.

10. The method of removing hair of claim 9 wherein the gliding step comprises moving the vacuum cleaner in the second direction.

11. The method of removing hair of claim 10 wherein the hair collection element comprises at least one projection oriented at an angle of about 45° with respect to the surface to be cleaned.

12. The method of removing hair of claim 10 wherein the hair collection element is configured to rotate when the cleaning head is moved in the second direction.

13. The method of removing hair of claim 10 wherein the hair collection element is configured to glide over the surface to be cleaned when the cleaning head is moved in the second direction.
