2. The agitator of claim 1 , wherein the first end region of the deformable flap includes a second taper.
3. The agitator of claim 2 , wherein the first taper has a first slope and the second taper has a second slope, the first slope being different from the second slope.
4. An agitator for a vacuum cleaner comprising:
a body; and
a deformable flap extending from the body and comprising a combination of a flexible material and fabric, the fabric including a woven material, the deformable flap including at least one taper at an end region of the deformable flap, the at least one taper causing a height of the deformable flap in at least a portion of the end region to be less than a height of the deformable flap in a central region of the deformable flap, wherein the height of the deformable flap extends from a base of the deformable flap to a cleaning edge of the deformable flap, the base of the deformable flap is secured to the body.
5. The agitator of claim 4 , wherein the deformable flap includes a selvedge along the cleaning edge.
6. The agitator of claim 5 , wherein the base has a plurality of segments that, when mounted to the body, cause the taper to be formed within the deformable flap.
7. The agitator of claim 1 , further comprising a second deformable flap, wherein the first and the second deformable flap extending helically around the body, and, wherein, a length of the first and the second deformable flap is less than a length of the body.
8. The agitator of claim 7 , wherein the second deformable flap extends from the second end region of the body to the central region of the body.
9. The agitator of claim 1 further comprising at least one bristle strip, the at least one bristle strip extending substantially parallel to the first deformable flap.
10. The agitator of claim 9 , wherein a length of the at least one bristle strip is less than a length of the first deformable flap.
11. A vacuum cleaner comprising:
an agitator chamber including one or more ribs, wherein the one or more ribs are disposed at opposing distal ends of the agitator chamber; and
an agitator disposed within the agitator chamber such that at least a portion of the agitator engages the one or more ribs, the agitator including:
a body; and
at least one deformable flap extending from the body, the deformable flap includes at least one taper, the at least one taper causing a cleaning edge of the deformable flap to approach the body.
12. The vacuum cleaner of claim 11 , wherein the at least one taper includes a first taper and a second taper, the first and second tapers extending within opposing end regions of a corresponding deformable flap.
13. The vacuum cleaner of claim 11 , wherein the one or more ribs extend from an agitator cover.
14. The vacuum cleaner of claim 13 , wherein the agitator cover is an end cap.
15. The vacuum cleaner of claim 11 wherein the agitator further comprises at least one bristle strip, the at least one bristle strip extending substantially parallel to a corresponding deformable flap.
16. The vacuum cleaner of claim 15 , wherein a length of the at least one bristle strip is less than a length of the corresponding deformable flap.
17. The vacuum cleaner of claim 11 , wherein the at least one taper includes a first taper and a second taper, each taper extending in a corresponding end region of the deformable flap.
18. The vacuum cleaner of claim 11 , wherein the body includes a taper that extends towards a central region of the body.
19. An agitator for a vacuum cleaner comprising:
a body; and
at least one deformable flap extending from the body, the deformable flap includes a first end region, a second end region opposite the first end region, a central region disposed therebetween, and at least one taper, the at least one taper causing a cleaning edge of the deformable flap to approach the body, wherein the at least one taper includes a first taper and a second taper disposed in the first and second end region of the deformable flap, respectively, wherein the first and the second taper each have a height that decreases as a distance from the central region increases.
20. The agitator of claim 19 , wherein the deformable flap comprises a combination of a flexible material and fabric, the fabric including a woven material.
21. The agitator of claim 20 , wherein the deformable flap includes a selvedge along the cleaning edge.
22. An agitator for a vacuum cleaner comprising:
a body;
at least one deformable flap extending from the body, the deformable flap includes at least one taper, the at least one taper causing a cleaning edge of the deformable flap to approach the body; and
at least one bristle strip, the at least one bristle strip extending substantially parallel to a corresponding deformable flap, wherein a length of the at least one bristle strip is less than a length of the corresponding deformable flap.
23. The agitator of claim 22 , wherein the deformable flap comprises a woven material.
24. The agitator of claim 23 , wherein the deformable flap includes a selvedge along the cleaning edge.
