Abstract: A dirt separator for separating dirt from an airflow in a vacuum cleaner includes a primary separation stage (20), a secondary separation stage (30) and a movable member (40). The primary separation stage has a first dirt collection chamber (22) for storing first dirt removed from the airflow by a first filter comprised in the primary separation stage. The secondary separation stage is downstream of the primary separation stage and has a second dirt collection chamber (32) for storing second dirt removed from the airflow by a second filter comprised in the second separation stage. The movable member is movable relative to the first and second filters to disengage the first dirt and the second dirt from the first and second filters. respectively.

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 includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The inlet is defined by an end of an inlet duct that extends within the chamber, and a separation distance between the centre of the inlet and the centre of the disc is no greater than the diameter of the inlet.

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 dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The disc comprises a perforated region and a non-perforated region. The holes are then formed in the perforated region, and the width of the non-perforated region is no less than the diameter of the inlet.
