Abstract

A multi-function cleaning tool for use with a suction cleaner having a suction source includes a nozzle body rotatably coupled to a housing assembly, where the nozzle body includes multiple suction nozzles and/or agitators that are configured to clean different portions of a surface to be cleaned, such as a stairway.

First claim

What is claimed is:

1. A cleaning tool for a suction cleaner having a suction source, the cleaning tool comprising:
a housing assembly with an outlet for fluid communication with the suction source; and
a multi-function nozzle body rotatably mounted on the housing assembly and comprising at least two suction nozzle openings that are fluidly isolated from each other, with each of the at least two suction nozzle openings having an agitator;
wherein rotation of the nozzle body on the housing assembly selectively places one of the at least two suction nozzle openings in fluid communication with the outlet; and
wherein the agitators for the at least two suction nozzle openings are selected from a group comprising a straight brush, a concave brush, and an angled brush;
wherein the at least two suction nozzle openings comprises three suction nozzle openings, and the agitators for the three suction nozzle openings comprise one straight brush, one concave brush, and one angled brush.

2. The cleaning tool according to claim 1 wherein each of the agitators comprises a plurality of bristle tufts adjacent to the associated suction nozzle opening in an orientation conforming to the shape of the associated suction nozzle opening.

3. The cleaning tool according to claim 1 wherein the housing assembly further comprises a grip defining the outlet, wherein the nozzle body can be rotated relative to the grip.

4. The cleaning tool according to claim 3 and further comprising a collar on the nozzle body that is rotatably coupled in a corresponding bearing on the grip.

5. The cleaning tool according to claim 1 and further comprising three separate working air channels through the nozzle body leading from one of the three suction nozzle openings to one of three separate suction nozzle outlets, wherein rotation of the nozzle body on the housing assembly selectively places one of the three suction nozzle outlets in fluid communication with the outlet.

6. The cleaning tool according to claim 5 and further comprising a valve plug fluidly positioned between the suction nozzle openings and the outlet, the valve plug having an opening aligned with one of the three suction nozzle outlets and adapted to block the remaining suction nozzle outlets.

7. The cleaning tool according to claim 5 wherein the nozzle body comprises a nozzle cover mounted to a nozzle back plate to form a cavity, with the working air channels extending therethrough.

8. The cleaning tool according to claim 7 wherein the nozzle cover is removable from the nozzle back plate.

9. The cleaning tool according to claim 8 wherein the nozzle cover comprises a pull tab for releasing the nozzle cover from the nozzle back plate.

10. The cleaning tool according to claim 1 wherein the nozzle body is indexible between three discrete positions such that one of the three suction nozzle openings is in fluid communication with the outlet in each discrete position.

11. The cleaning tool according to claim 10 and further comprising a rotational detent between the nozzle body and the housing assembly configured to nest in one of three slots, with each slot corresponding to one of the three discrete positions.

12. The cleaning tool according to claim 1 and further comprising a fluid distributor adapted to be fluidly coupled to a source of cleaning fluid for distributing cleaning fluid onto a surface to be cleaned.

13. The cleaning tool according to claim 12 wherein the fluid distributor comprises a spray tip mounted on the housing assembly such that the position of the spray tip does not change when the nozzle body is rotated.

14. A cleaning tool for a suction cleaner having a suction source, the cleaning tool comprising:
a housing assembly with an outlet for fluid communication with the suction source; and
a multi-function nozzle body rotatably mounted on the housing assembly and comprising a straight suction nozzle, a concave suction nozzle, and an angled suction nozzle that are fluidly isolated from each other;
wherein rotation of the nozzle body on the housing assembly selectively places one of the straight suction nozzle, the concave suction nozzle, or the angled suction nozzle in fluid communication with the outlet.

15. The cleaning tool according to claim 14 , wherein the housing assembly further comprises a grip defining the outlet, wherein the nozzle body can be rotated relative to the grip.

16. The cleaning tool according to claim 14 wherein each of the suction nozzles comprise separate working air channels through the nozzle body, and wherein rotation of the nozzle body on the housing assembly selectively places one of the working air channels in fluid communication with the outlet.

17. The cleaning tool according to claim 16 and further comprising a valve plug fluidly positioned between the suction nozzles and the outlet, the valve plug having an opening aligned with one of the working air channels and adapted to block the remaining working air channels.

18. The cleaning tool according to claim 14 and further comprising a fluid distributor adapted to be fluidly coupled to a source of cleaning fluid for distributing cleaning fluid onto a surface to be cleaned, wherein the fluid distributor comprises a spray tip mounted on the housing assembly such that the position of the spray tip does not change when the nozzle body is rotated.

19. A cleaning tool for a suction cleaner having a suction source, the cleaning tool comprising:
a housing assembly with an outlet for fluid communication with the suction source; and
a multi-function nozzle body rotatably mounted on the housing assembly and comprising at least three suction nozzles that are fluidly isolated from each other, wherein the multi-function nozzle body comprises:
a nozzle back plate; and
a nozzle cover mounted to the nozzle back plate and forming a cavity therewith having at least three isolated working air channels, wherein each of the at least three isolated working air channels is fluidly connected with one of the at least three suction nozzles;

wherein rotation of the multi-function nozzle body on the housing assembly selectively places one of the at least three suction nozzles in fluid communication with the outlet via the associated one of the at least three isolated working air channels.

20. The cleaning tool according to claim 19 and further comprising an agitator associated with each of the at least three suction nozzles.
