摘要： 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.

摘要： 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. The cleaner head further includes a plurality of guide members for guiding into the suction chamber debris entrained within air drawn towards the suction inlet. Each guide member is arranged to rotate with a respective caster about the first axis.

摘要： 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.

摘要： A cleaner head that includes a main body having an agitator chamber, an axle that extends into the chamber, a bearing assembly mounted on the axle, a biasing member, and an agitator mounted on the bearing assembly. The bearing assembly is moveable along the axle between a first position and a second position. The biasing member then biases the bearing assembly towards the first position, and the agitator pushes the bearing assembly against the biasing member towards the second position.

摘要： A cleaning appliance having a cleaner head rotatably attached to a duct. The cleaner head includes a main body having an agitator chamber, an agitator rotatably mounted within the agitator chamber, and a drive assembly coupled to the agitator such that torque generated by the drive assembly is transmitted to the agitator. The drive assembly is located within the agitator such that the centre of gravity of the cleaner head is located on or near a vertical plane containing the rotational axis about which the cleaner head rotates relative to the duct.

摘要： A vacuum cleaner has a removable cyclonic separator that includes a cyclone chamber; a dirt-collection chamber, open at one end; and an outlet duct from the cyclone chamber. An open end of the outlet duct is arranged for connection to a motor intake duct on the cleaner, the outlet duct and dirt collection chamber sharing a common wall section which divides the open end of the outlet duct from the open end of the dirt collection chamber. A cover closes off the open end of the dirt collection chamber and can be opened to allow access to the dirt collection chamber for emptying. When the cover is in the closed position, a cover sealing member forms an air seal between the cover and the common wall section. When the outlet duct is connected to the motor inlet duct, an outlet duct sealing member forms an air seal between the ducts.

摘要： 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.
