AGITATOR ASSEMBLY
First Claim
1. An agitator assembly for use in a cleaning apparatus, the agitator assembly including:
- an agitator including a body with a first end and a second end, and a first alignment formation and a first securing formation adjacent the first end; and
a drive member operable to impart rotation about a drive axis, and including a second alignment formation adapted to cooperate with the first alignment formation, and a second securing formation adapted to engage the first securing formation;
wherein relative axial movement of the agitator in a first direction towards the drive member causes contact between the first and second alignment formations;
further relative axial movement of the agitator in the first direction causes relative rotation between the agitator and the drive member; and
yet further relative axial movement of the agitator in the first direction causes engagement between the first and second securing formations, substantially to prevent further relative rotational movement between the agitator and the drive member.

Abstract
An agitator assembly for a cleaning apparatus including an agitator having a body with first and second ends, and a first alignment formation and a first securing formation at or adjacent the first end; and a drive member operable to impart rotation about a drive axis, and a second alignment formation adapted to cooperate with the first alignment formation, and a second securing formation adapted to engage the first securing formation. Relative axial movement of the agitator in a first direction towards the drive member causes contact between the first and second alignment formations. Further relative axial movement of the agitator in the first direction causes relative rotation between the agitator and drive member and yet further relative axial movement of the agitator in the first direction causes engagement between the first and second securing formations, substantially to prevent further relative rotational movement between the agitator and drive member.

3. An agitator assembly for use in a cleaning apparatus, the agitator assembly including:
-
an agitator including a body with a first end and a second end, and a first alignment formation adjacent the first end and a user-graspable member at the second end, the user-graspable member being rotatable relative to the body; and a drive member operable to impart rotation about a drive axis, and including a second alignment formation adapted to cooperate with the first alignment formation; wherein relative axial movement of the agitator in a first direction towards the drive member causes contact between the first and second alignment formations; and wherein further relative axial movement of the agitator in the first direction causes relative rotation between the agitator and the drive member, and relative rotation between the body and the user-graspable member of the agitator. - View Dependent Claims (4, 20, 21, 22, 23)
