## Abstract

An agitator for a surface treating appliance. The agitator comprises an agitator body having an axis, and a bristle strip carried on the agitator body and extending along a central region of the agitator body and an end region of the agitator body. The bristle strip includes a plurality of bristles aligned in a row, and wherein bristles associated with the end region of the agitator extend in a direction that defines an acute angle with the longitudinal axis of the agitator. In this way, the bristles on the ends of the agitator are provided with a outwardly swept configuration that increases the effective swept width of the agitator.

## Claims

### Claim 1

A rotatable agitator for a surface treating appliance, the agitator comprising an agitator body having an axis, and a bristle strip carried on the agitator body and extending along a central region of the agitator body and an end region of the agitator body, wherein the bristle strip comprises a plurality of bristles aligned in a row, and wherein bristles associated with the end region of the agitator extend in a direction that defines an acute angle with the longitudinal axis of the agitator.

### Claim 2 (depends on 1)

The agitator of claim 1, wherein bristles associated with the central region of the agitator extend in a direction substantially perpendicular to the axis of the agitator.

### Claim 3 (depends on 1)

The agitator of claims 1, wherein the bristle strip comprises a plurality of filaments arranged on a base.

### Claim 4 (depends on 3)

The agitator of claim 3 wherein the plurality of filaments extend in a perpendicular direction away from the base.

### Claim 5 (depends on 1)

The agitator of claim 1, wherein the agitator is configured such that a first strip portion of the bristle strip extends in a direction that is substantially parallel to or diverges away from the axis and a second strip portion of the bristle strip extends in a direction which converges on the axis.

### Claim 6 (depends on 1)

The agitator of claim 1, wherein the end region is provided by an end member securable to the central region of the agitator.

### Claim 7 (depends on 1)

The agitator of claim 1, wherein the bristle strip is received in a track provided on the agitator.

### Claim 8 (depends on 7)

The agitator of claim 7, wherein the agitator is configured such that a first strip portion of the bristle strip extends in a direction that is substantially parallel to or diverges away from the axis and a second strip portion of the bristle strip extends in a direction which converges on the axis, and wherein the track includes a central track section provided on the central region of the agitator and an end track section provided on the end member of the agitator.

### Claim 9 (depends on 8)

The agitator of claim 8, wherein the central track section traces a helical path about the central region of the agitator.

### Claim 10 (depends on 8)

The agitator of claim 8, wherein the end track portion traces a linear path along the end member of the agitator.

### Claim 11 (depends on 8)

The agitator of claim 8, wherein end track section is provided with first and second inclined portions so that the filaments associated with the second track portion extend at an acute angle to the agitator axis.

### Claim 12 (depends on 11)

The agitator of claim 11, wherein the first inclined portion is directly adjacent the central region of the agitator main body and wherein the second inclined portion is directly adjacent the first inclined portion.

### Claim 13 (depends on 12)

The agitator of claim 12, wherein the first inclined portion has a positive gradient and the second inclined portion has a negative gradient.

### Claim 14
