  • Patent number: 9962046
    Abstract: A vacuum cleaning appliance comprises a handheld vacuum cleaning device comprising a motor coupled to a fan for generating an air flow through a nozzle air inlet. It also comprises a support frame comprising: a cleaning head having a cleaning head air inlet; and an air outlet in fluid communication with the cleaning head air inlet, the air outlet configured to couple with the nozzle air inlet when the handheld vacuum cleaning device is secured to the support frame and to create an airflow path from the cleaning head air inlet to the nozzle air inlet. The air outlet is moveable with respect to the support frame into a first position in which the air outlet projects from the support frame when the handheld vacuum cleaning device is detached from the support frame.

  • Patent number: 8101877
    Abstract: The present invention provides a rotating dual switching mechanism having a first switch and a first activator with rotational axis, and a second switch having a second activator that is offset from the rotational axis. A ring-shaped actuator is concentric with the rotational axis and is movable to actuate the second activator. A switch arm is rotatable about the rotation axis and has a first portion that actuates the first activator and a second portion for engaging and the ring-shaped actuator and hence the second activator. The switch arm is movable to a first position where both the first and second activator are “off,” a second position where the first activator is “on” and the second activator is “off,” and a third position where both the first and second activator are “on.

  • Patent number: 8032984
    Abstract: The present invention provides a vacuum cleaner having an inlet (26) for dirty air, an outlet (24) for clean air, and a filter (44) located in fluid communication between the inlet and the outlet. A motor drives a fan for moving air into the inlet and through the filter to the outlet. A filter cleaning mechanism for removing dirt from the filter is provided and is operatively associated with an on/off switch for the fan motor or alternatively a separate user-operated switch, whereby operation of the switch results in operation of the filler cleaning mechanism.
