| 摘要 |
The present invention relates to an agitator assembly for use in a cleaning apparatus, the assembly including: an agitator comprising a body with a first and a second end, 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 providing 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 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. |
