    摘要： A vacuum accessory tool comprises a nozzle body defining an interior, with an opening formed in the nozzle body and a working air conduit provided on the nozzle body in fluid communication with the opening via the interior. A hair removal assembly is associated with the nozzle body, and can include nubs from a flexible polymeric material adapted to generate an electrostatic charge when the tool moves over and in contact with a carpet surface.

    摘要： A cleaner head that includes a suction inlet for admitting a first airflow, a turbine inlet for admitting a second airflow, an outlet for discharging the first airflow and the second airflow and an agitator and its drive assembly. A first airflow path then carries the first airflow from the suction inlet to the outlet, and a second airflow path carries the second airflow from the turbine inlet to the outlet. The drive assembly includes a turbine that is driven by the second airflow. A baffle is located in the second airflow path and is movable between an open position in which the second airflow path is unrestricted and a closed position in which the second airflow path is restricted. The baffle is biased in the open position and moves to the closed position when the dynamic pressure of the second airflow at the baffle exceeds a threshold.

    摘要： A tool for a surface treating appliance, such as a vacuum cleaner, includes a housing having a suction opening. An agitator, such as a brush bar, is rotatably located in the suction opening of the housing. The interior of such a tool can get blocked due to large objects being drawn in through the suction opening, or else by threads and fibers becoming tangled in the brush bar. The brush bar may be removed through the suction opening for replacement or repair. A portion of the housing may also be removable to clear the way for the user to access a narrow opening in the neck of the tool which may be prone to blockage.

    摘要： A vacuum cleaning appliance includes a vacuum cleaning head having a suction opening, the head having a first state and a second state, a fan unit for drawing an air flow through the suction opening, and a control assembly for controlling the state of the head. The control assembly includes a user-operable valve for increasing temporarily an air pressure within an airflow path extending from the suction opening to the fan unit, a pressure chamber having an interior volume in fluid communication with the airflow path, the pressure chamber being moveable from an expanded configuration to a contracted configuration in response to a pressure difference between the interior volume and ambient air, the pressure chamber being biased towards the expanded configuration, and a control mechanism for allowing the pressure chamber to move to the contracted configuration in response to a first operation of the valve to place the head in one of the first and second states, and for preventing the pressure chamber from returning to the contracted configuration in response to a second operation of the valve to place the head in the other of the first and second states.

    摘要： A vacuum cleaner device comprises a main body, a brush device, and a vacuum driven motor. The main body has a primary vacuum inlet, a secondary vacuum inlet, and a vacuum outlet. The secondary vacuum inlet is operatively connected to the vacuum outlet. The brush device is configured and adapted to reciprocate relative to the main body. The vacuum driven motor is adapted and configured to be rotationally driven by air passing through the secondary vacuum inlet to the vacuum outlet. The vacuum driven motor is operatively connected to the brush device in a manner such that rotation of vacuum driven motor causes the brush device to reciprocate relative to the main body.
