  • Patent number: 11517166
    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.

  • Publication number: 20220079402
    Abstract: A cleaner head for a vacuum cleaner includes a suction cavity comprising an opening through which debris enters the cleaner head, and an outlet. An agitator is mounted in the suction cavity in a cantilevered manner for rotation relative thereto. The agitator includes a core having a first, free end, a second end remote from the free end, and upstanding helical ridges extending between the free end and the second end, and a row of bristles located between the helical ridges and inclined relative to the core in a direction extending towards the free end of the core.

  • Publication number: 20200214520
    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.

  • Publication number: 20200170465
    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.

  • Publication number: 20200163510
    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.
