Abstract: A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate about a rotational axis and including holes through which the cleansed fluid passes. When viewed normal to the disc, each hole is elongate and defines a longitudinal axis which runs within the plane of the disc. The longitudinal axis of each hole is curved.

Abstract: A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate in a predetermined direction about a rotational axis, and including holes running from an upstream face to a downstream face through which the cleansed fluid passes. When viewed along the radial direction of the disc, the path of each hole through the thickness of the disc defines a centreline, the centreline being inclined such that it is non-perpendicular to the disc. The centreline of each hole is inclined such that it intersects the upstream face of the disc at a point which is behind, in the direction of rotation of the disc, the point at which the centreline intersects the downstream face of the disc.

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 dirt separator including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber, and a disc located at the outlet, the disc being arranged to rotate about a rotational axis and including holes through which the cleansed fluid passes. The holes are distributed over at least first and second regions of the disc, the second region being radially outward of the first region. The porosity of the second region is higher than the porosity of the first region.
