Abstract

An attachment for a cleaning appliance includes a main body having a head and a passageway through which a fluid is able to flow. The head includes first and second suction openings, each of the first and second suction openings being arranged to engage with a surface to be cleaned. The first and second suction openings are in simultaneous communication with the passageway. By providing such an arrangement, both of the first and second suction openings are independently able to engage with a surface to be cleaned and a rotatable connection between the head and a neck is not required.

First claim

The invention claimed is:

1. An attachment for a vacuum cleaner comprising a main body, the main body having a head, a neck and a passageway through which a fluid is able to flow, the head including one or more air bleeds provided on one or more side walls of the head, and first and second suction openings, each of the first and second suction openings being arranged to engage with a surface to be cleaned, wherein the first and second suction openings are in simultaneous communication with the passageway, and the passageway extends through the neck, which is cylindrical and has a substantially constant inner diameter.

2. An attachment according to claim 1 , wherein each of the first and second suction openings is arranged to operate as a dirty air inlet when engaged with the surface to be cleaned and as an air bleed when remote from the surface to be cleaned.

3. An attachment according to claim 2 , wherein the first and second suction openings are arranged such that when one of the first and second suction openings operates as a dirty air inlet, the other of the first and second suction openings operates as an air bleed.

4. An attachment according to claim 2 or 3 , wherein the neck has a longitudinal axis, and the first suction opening is configured to operate either as a dirty air inlet or as an air bleed depending upon the angle of the longitudinal axis with respect to the surface to be cleaned.

5. An attachment according to claim 4 , wherein the first suction opening operates as a dirty air inlet when the angle between the longitudinal axis and the surface to be cleaned is less than 45° and as an air bleed when the angle of the longitudinal axis with respect to the surface to be cleaned is 45° or more.

6. An attachment according to claim 2 or 3 , wherein the neck has a longitudinal axis, and the second suction opening operates either as a dirty air inlet or as an air bleed depending upon the angle of the longitudinal axis with respect to the surface to be cleaned.

7. An attachment according to claim 6 , wherein the second suction opening is configured to operate as a dirty air inlet when the angle between the longitudinal axis and the surface to be cleaned is 45° or more and as an air bleed when the angle of the longitudinal axis with respect to the surface to be cleaned is less than 45 °.

8. An attachment according to claim 1 , 2 or 3 , wherein the first suction opening lies in a first plane and the second suction opening lies in a second plane and the first plane lies at an angle to the second plane.

9. An attachment according to claim 8 , wherein the first plane lies at an angle to the second plane which is in the range of 30 to 60°.

10. An attachment according to claim 1 , 2 or 3 , wherein the first and second suction openings are of substantially the same cross-sectional area.

11. An attachment according to claim 1 , 2 or 3 , wherein the first and second suction openings are separated by a partition.

12. An attachment according to claim 11 wherein the partition forms a partial barrier between the first and second suction openings.

13. An attachment according to claim 1 , 2 or 3 , wherein the first suction opening is bounded on one side by a first lip and the second suction opening is bounded on one side by a second lip located on the opposite side of the head to the first lip.

14. An attachment according to claim 13 , further comprising one or more lint pickers which run along the substantially the entire length of the first or second lip.

15. A vacuum cleaner comprising the attachment according to claim 1 , 2 or 3 .
