  • Patent number: 8100999
    Abstract: A separating apparatus for a cleaning appliance, such as a vacuum cleaner, includes a separator for separating dirt and dust from a fluid flow and a collecting chamber arranged to collect dirt and dust separated by the separator. A first catch for opening a closure member on the collecting chamber is provided, with first releasing means for releasing this catch. There is also provided a second catch for releasing the collecting chamber from the separator and second releasing means for releasing the second catch. The second releasing means is inaccessible when the first catch is engaged. A cover associated with the first releasing means obscures the second releasing means until the first catch has been released. The invention prevents the user from accidentally releasing the collecting chamber from the separator when it was the user's intention simply to empty dirt and dust from the collecting chamber.

  • Patent number: 7900317
    Abstract: A vacuum cleaner includes a cyclonic airflow chamber that facilitates the separation of contaminants from a suction airstream. The airflow chamber includes a chamber inlet and a chamber outlet, with the chamber inlet being fluidically connected with at least one of a suction nozzle and an above-the-floor cleaning tool. An exhaust filter housing includes a suction duct and an exhaust plenum, with the suction duct communicating with the chamber outlet. A suction source housing includes an open end communicating with the exhaust plenum and a closed end. A suction source is positioned within the suction source housing to define an annular exhaust flow passageway surrounding the suction source from the housing closed end to the housing open end. The suction source includes a suction inlet communicating with the suction duct and an exhaust outlet communicating with the housing closed end.

  • Patent number: 7725984
    Abstract: A bare floor cleaner for wet and dry bare floor surfaces comprises a base with wet and dry suction nozzles and a handle pivotally connected to the base. A diverter mounted in the working air conduit between each of the dry suction nozzle and the wet suction nozzle to a recovery tank is movable by movement of the handle between a dry suction position and a wet suction position for selectively at least partially blocking working air flow from the wet suction nozzle and the dry suction nozzle, respectively, to the recovery tank. A shut-off valve is mounted in the recovery tank to prevent fluid communication between a suction source and the recovery tank when the amount of liquid in the recovery tank reaches a first predetermined amount with the handle forward and a second predetermined amount with the handle rearward.
