Abstract

A surface cleaning device may include a nozzle, a dust cup, a suction motor configured to draw air into the nozzle and through the dust cup, and a first deodorizer coupled to the nozzle, the first deodorizer includes a deodorizing composition having a long chain fatty acid.

First claim

What is claimed is:

1. A surface cleaning device comprising:
a nozzle;
a first rotating agitator rotatably coupled to the nozzle, the first rotating agitator configured to rotate about a first longitudinal axis; and
a first deodorizer coupled to the nozzle and configured to directly contact an outer surface of the first rotating agitator as the first rotating agitator rotates about the longitudinal axis, the first deodorizer includes a deodorizing composition having a long chain fatty acid.

2. The surface cleaning device of claim 1 , wherein the long chain fatty acid is a stearic acid.

3. The surface cleaning device of claim 2 , wherein the deodorizing composition is 50 to 100 weight % stearic acid.

4. The surface cleaning device of claim 1 , wherein the first deodorizer includes a first portion formed of the long chain fatty acids and a second portion formed of an odor control compound.

5. The surface cleaning device of claim 4 , wherein the odor control compound comprises zinc ricinoleate.

6. The surface cleaning device of claim 1 , wherein the deodorizing composition comprises a carrier material.

7. The surface cleaning device of claim 6 , wherein the carrier material comprises paraffin wax.

8. The surface cleaning device of claim 1 , wherein the first rotating agitator is a foam roller.

9. The surface cleaning device of claim 1 , further comprising a second deodorizer coupled to the nozzle.

10. The surface cleaning device of claim 9 , wherein the second deodorizer is configured to directly engage a surface to be cleaned.

11. The surface cleaning device of claim 1 , wherein the first deodorizer is removably coupled to the nozzle.

12. The surface cleaning device of claim 11 , wherein the first deodorizer includes a cartridge body.

13. The surface cleaning device of claim 12 , wherein the nozzle includes a cartridge receptacle configured to receive the cartridge body.

14. The surface cleaning device of claim 13 , wherein the cartridge receptacle includes a latch configured to releasably engage the cartridge body.

15. The surface cleaning device of claim 1 further comprising a second rotating agitator.

16. The surface cleaning device of claim 15 , wherein the first rotating agitator is different from the second rotating agitator.

17. The surface cleaning device of claim 15 , further comprising:
a dust cup; and
a suction motor;
the nozzle further including a front side, a back side, and an opening on an underside of the nozzle between the front side and the back side, the opening fluidly coupled to the suction motor;
wherein the second rotating agitator is mounted to the nozzle within the suction conduit and configured to rotate about a second longitudinal axis; and
wherein the first rotating agitator is closer to the front of the nozzle than the second rotating agitator.

18. The surface cleaning device of claim 17 , wherein the first rotating agitator is a foam roller and the second rotating agitator is a brush roll.

19. The surface cleaning device of claim 1 , wherein the first deodorizer includes an engagement surface configured to directly contact the outer surface of the first rotating agitator.

20. The surface cleaning device of claim 19 , wherein the engagement surface includes a profile that corresponds with a profile of the first rotating agitator.
