Disclosed is an attachment for a hand held appliance comprising an inlet; an outlet; and a fluid flow path between the inlet and the outlet, wherein the outlet comprises at least one slot extending from near an inlet end of the attachment towards a distal end of the attachment and wherein the outlet is at least partially defined by an external surface of the attachment wherein fluid emitted from the outlet is blown along the external surface. The slot may extend substantially along the length of the attachment and fluid emitted from the outlet is attracted to the surface of the attachment. The outlet may comprise a plurality of slots radially spaced around the attachment. Fluid emitted from the outlet flows around the external surface of the attachment and is tangential to the external surface of the attachment. The attachment has a longitudinal axis extending from the first end to the distal end and the at least one slot may be parallel to the longitudinal axis, alternatively the at least one slot is non-parallel to the longitudinal axis. The attachment may further comprise a flow directing element between the inlet and the outlet. Also disclosed is an appliance including such as attachment.

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).

A cleaning implement (8, 10) comprising a connector (22) for connecting the cleaning implement (8, 10) to a vacuum cleaner (4) such that the cleaning implement (8, 10) is in fluid communication with the vacuum (cleaner4). The connector (22) comprises an engagement portion (38) and a catch (44) pivotally connected to the engagement portion (38) such that the catch (44) has a pivot axis X, the catch (44) comprises a pressing portion (52) spaced from the pivot axis X and a latching element (50) arranged on a portion of the catch (44) extending from the pivot axis X to the pressing portion (52). The catch (44) is arranged such that pressing on the pressing portion (52) pivots the catch (44) from a first configuration in which the latching element (50) is in an engagement position for preventing disengagement of the connector (22) from the vacuum cleaner (4), to a second configuration in which the latching element (50) is in a disengagement position in which the connector (22) can be disengaged from the vacuum cleaner (4).

A cleaner head (2) for a cleaning appliance, comprising a main body (4) having an air inlet (14) and an air outlet (16), an agitator (6) supported for rotation with respect to the main body (4) about a rotational axis, and a collector (56) for collecting strands of hair. The collector (56) is supported by the main body (4) and arranged such that strands of hair drawn through the air inlet (14) wrap around at least part of the collector (56). The collector (56) is movable with respect to the main body (4) between a hair collecting position in which the agitator (56) is rotatable with respect to the collector (56) and a hair removal position.

A handle assembly for a vacuum cleaner comprising a handle, a duct, a valve assembly, and a cover. The handle is attached to the duct, which has an inlet at one end, an outlet at an opposite end, and a bleed aperture located between the inlet and the outlet. The valve assembly comprises a valve and an actuator. The valve is moveable between a closed position and an open position, with the valve closing the bleed aperture when in the closed position and opening the bleed aperture when in the open position. The actuator moves the valve from the closed position to the open position when actuated. The cover surrounds the duct such that an upper part of the cover overlies the bleed aperture and the valve, and one or more holes are formed in a lower part of the cover. During use, suction at the outlet causes a primary airflow to be drawn into the duct via the inlet. Additionally, when the valve is in the open position, the suction causes a secondary airflow to be drawn in through the holes, around the space between the duct and the cover, and into the duct via the bleed aperture.
