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 inclined relative to the radial direction of the disc.

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 running from an upstream face to a downstream face through which the cleansed fluid passes. Each hole has a tapered portion which narrows from an upstream end to a downstream end thereof.

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 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 a spout that is connected to the inlet, wherein the spout comprises a spout outlet through which the fluid flow is discharged into the separating volume, and wherein the spout is configured to direct the fluid flow across the filter screen.

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.

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.
