<p>A cleaning appliance (60) comprising a cleaner head (1) rotatably attached to a duct (61). The cleaner head (1) comprises a main body (2) having an agitator chamber (10), an axle (21) that extends into the chamber (10), a drive assembly (7) mounted on the axle (21), and an agitator (8) rotatably mounted within the agitator chamber (10) so as to surround the drive assembly (7). The drive assembly (7) is coupled to the agitator (8) such that torque generated by the drive assembly (7) is transmitted to the agitator (8). Furthermore, the drive assembly (7) is mounted along the axle (21) such that the centre of gravity of the cleaner head (1) is located on or near a vertical plane (63) containing the rotational axis (62) about which the cleaner head (1) rotates relative to the duct (61).</p> |
