Abstract

A cleaner head for a vacuum cleaner, comprising an agitator; and a housing defining a chamber which at least partially surrounds the agitator, a dirty air inlet in a lower part of the chamber and a dirty air outlet, wherein a partition is disposed between the agitator and the dirty air outlet such that the partition and the housing define a settling region of the chamber adjacent the dirty air outlet, the partition is provided with a first debris opening and a second debris opening disposed above the first debris opening such that, in use, debris swept past the first debris opening by the agitator is swept towards the second debris opening.

Claims

1. A cleaner head for a vacuum cleaner, comprising:

an agitator; and

a housing defining a chamber which at least partially surrounds the agitator, a dirty air inlet in a lower part of the chamber and a dirty air outlet, wherein a partition is disposed between the agitator and the dirty air outlet such that the partition and the housing define a settling region of the chamber adjacent the dirty air outlet, the partition is provided with a first debris opening and a second debris opening disposed above the first debris opening such that, in use, debris swept past the first debris opening by the agitator is swept towards the second debris opening, and a debris diverter is disposed within the chamber above the second debris opening and rearward of a longitudinal axis of the agitator with respect to a forward direction of travel of the cleaner head and is arranged to deflect debris through the second debris opening.

2. The cleaner head of claim 1, wherein the debris diverter comprises an upper edge of the second debris opening which projects forwardly of a lower edge of the second debris opening.

3. The cleaner head of claim 1, wherein a debris deflector is disposed between the second debris opening and the settling region of the chamber, the debris deflector being arranged to deflect debris into the settling region of the chamber.

4. The cleaner head of claim 3, wherein the partition defines a debris passageway extending between the second debris opening and the settling region of the chamber.

5. The cleaner head of claim 4, wherein the debris deflector comprises a wall of the debris passageway.

6. The cleaner head of claim 1, wherein the agitator comprises a brush bar and the second debris opening is in the form of a slot that extends substantially parallel with the longitudinal direction of the brush bar.

7. The cleaner head of claim 6, wherein the first debris opening is in the form of a slot that extends substantially parallel with the second debris opening.

8. The cleaner head of claim 1, wherein the housing and the partition define an agitating region of the chamber in which the agitator is housed.

9. The cleaner head of claim 8, wherein the agitating region of the chamber has a front opening that exposes the agitator at the front of the housing.

10. A vacuum cleaner comprising the cleaner head of claim 1.

11. The cleaner head of claim 1, wherein the partition defines a debris passageway extending between the second debris opening and the settling region of the chamber.
