  • Patent number: 12137865
    Abstract: A cleaner head for a vacuum cleaning appliance includes a housing which defines a suction chamber. The suction chamber has a suction inlet through which air enters the suction chamber, and a suction port through which air exits the suction chamber. The cleaner head includes a plurality of casters for supporting the cleaner head. Each caster is rotatable relative to the housing about a first axis which is perpendicular to the suction inlet. Each caster is also rotatable relative to the housing about a second axis perpendicular to the first axis.

  • Publication number: 20240081591
    Abstract: An autonomous surface cleaning apparatus includes a body, a drive system carried by the body, and a cleaning assembly disposed at a front of the body. The cleaning assembly includes a housing defining a suction chamber and a suction channel extending from the suction chamber to a suction channel opening provided in a first side surface of the cleaning assembly, and a side suction nozzle mounted to an extension and retraction assembly that is arranged to allow the side suction nozzle to be moved between an extended position. The side suction nozzle includes a first resilient blade and a second resilient blade, the first resilient blade being arranged such that a surface of the first resilient blade is substantially forward facing and the second resilient blade being arranged such that a surface of the second resilient blade is substantially downward facing.

  • Patent number: 11844485
    Abstract: A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.

  • Publication number: 20230346180
    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.

  • Publication number: 20220346612
    Abstract: A cleaner head including suction chamber having a suction opening; an agitator including a hollow body and supported the suction chamber by a support member, the support member having a first end that is fixed to a side wall of the suction chamber,and second end that free and over which the hollow body of the agitator can be slideably received; and a drive assembly forming part of the support member, and arranged to rotate the agitator about an axis. The fixed end of the support member is pivotal fixed to the side all of the suctionchamber such that the free end of the support member, together with the agitator supported thereon, can be pivoted to protrude out frome suction opening, to allow the agitator o be removed and replaced.
