Abstract: A separator for a cleaning device, the separator comprising: a housing that encloses a separating volume, the housing comprising an inlet for receiving a fluid flow containing entrained debris into the separating volume, and an outlet for discharging a filtered fluid flow output from the separating volume; a filter screen disposed on or in the housing to define part of a boundary of the separating volume, the filter screen being configured to retain the debris in the separating volume while allowing air to exit the separating volume to flow to the outlet; and an extractor arrangement providing fluid communication between the separating volume and a low-pressure region of the separator that is at lower pressure than the separating volume, in use, such that fluid is drawn into the extractor arrangement from the separating volume.

Abstract: A vacuum cleaner includes a filtration chamber with an inner wall and an outer wall, an air inlet arranged to feed air carrying dust particles into the space between the inner wall and outer wall of the filtration chamber and a dirt chute for discharging dirt and/or dust from the vacuum cleaner. A tapered filter is located between the inner wall and the outer wall of the filtration chamber. The tapered filter includes a narrow end and a wide end, and the narrow end of the filter is located at or proximate to the air inlet and/or the dirt chute.

Abstract: A cleaner head for a vacuum cleaning appliance includes a housing, a front agitator and a rear agitator. A suction chamber is located between the front agitator and the rear agitator. A baffle is located within the suction chamber between the agitators. During use of the cleaner head, debris becomes entrained within air drawn towards the suction chamber. Guide members mounted on the housing guide the entrained debris towards the suction chamber, whereas the baffle guides the air upwardly towards a central suction port of the suction chamber.

Abstract: A cleaner head for a vacuum cleaning appliance, the cleaner head including a main body supporting an agitator. The agitator includes a rotatable cylindrical body that bears an elongate agitator formation for engaging a floor surface as the cylindrical body rotates. The elongate agitator formation includes a first agitator row extending around the cylindrical body from a respective first edge L of the cylindrical body towards its centre C in a first helical direction and a second agitator row extending around the cylindrical body from a respective second edge R of the cylindrical body towards its centre C in a second helical direction that is counter to the first helical direction, wherein the first agitator row includes agitators of a first material and wherein the second agitator row includes agitators of a second material that is different to the first material.
