  • Patent number: 8291545
    Abstract: An upright vacuum cleaner includes a housing having a suction airstream inlet and a suction airstream outlet. A dirt container is selectively mounted to the housing for receiving and retaining dirt and dust separated from the suction airstream and includes a first cyclonic air-flow chamber and a second cyclonic airflow chamber. The chambers are spaced apart and are each approximately vertically oriented and arranged in a parallel relationship. An air manifold is disposed at a top portion of the dirt container. The air manifold includes an inlet section through which dirty air passes and an outlet section. The inlet section directs a flow of dirty air into two separate inlet conduits leading to a respective one of the first and second airflow chambers. The outlet section collects a flow of cleaned air from both of the chambers and merges the flow of cleaned air into a single outlet conduit.

  • Patent number: 7797792
    Abstract: A floor cleaning device (10) includes a housing (40) and a container (43) removably received by the housing. A suction nozzle (18, 18?, 18?) is fluidly connected with the container and with a suction source (52) when the container is received by the housing. A filter (114) is selectively fluidly connected with the container and with the suction source. A float (170) selectively closes the fluid connection of the filter with the container. The filter and the float may be removable as a unit (42) from the cleaning device. The nozzle may be removable, allowing an appropriate nozzle to be selected according to the type of floor surface to be cleaned.

  • Patent number: 7632324
    Abstract: The present invention relates to an upright vacuum cleaner including a housing and a nozzle base having a main suction opening. The housing is pivotally mounted on the nozzle base. The housing comprises a cyclonic separator including a dirty air inlet and a sidewall. A lower end of the separator being secured to a lower skirt. A dust collector section is located beneath the separator and includes a sidewall. A perforated tube is disposed within the separator. The perforated tube includes a shroud extending away from a closed lower end of the perforated tube. A diameter of the shroud is larger than a diameter of the separator lower end. The lower skirt and the shroud define a first air channel for directing air from the separator into the dust collector section. The first air channel has a substantially constant volume for maintaining airflow velocity.

  • Patent number: 7603744
    Abstract: A robotic appliance with a joystick sensor and associated methods of operation are provided. In one embodiment, the robotic appliance includes: a housing, a joystick sensor configured to provide sensed signals that vary as the robotic appliance traverses a surface area and comes in contact with an obstacle, a controller adapted to receive the sensed signals, wherein the controller determines the direction of the obstacle in relation to the robotic appliance and an x-y plane corresponding to the surface area based on the sensed signals and controls the robotic appliance based on the direction of the obstacle, a propelling mechanism, and a bumper that defines a periphery for a front section and a rear section of the robotic appliance in the x-y plane, wherein the bumper is in operative communication with the joystick sensor so that movement of the bumper in relation to the housing varies the sensed signals.

  • Patent number: 7599758
    Abstract: A vacuum cleaner includes a housing, a height adjust mechanism disposed on the housing and a height adjust motor, disposed within said housing that controls a height of the height adjust mechanism. A position element is mounted to said housing. A sensor processor, mounted to said housing, is in communication with the position element to provide a signal that relates to a position of the height adjust mechanism based at least in part upon data received from the position element. A controller processor, mounted to said housing, is in communication with the sensor processor for selectively controlling a height of the height adjust mechanism relative to a subjacent surface on which the vacuum cleaner is positioned. A height adjust mechanism height motor controller is in communication with the controller processor, for driving the height adjust motor to locate the height adjust mechanism in an appropriate position relative to the subjacent surface.
