  • Patent number: 11627852
    Abstract: A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway.

  • Patent number: 11197592
    Abstract: A vacuum cleaner (10) includes a handle assembly (22) pivotally coupled to a foot (42). The handle assembly (22) includes an air treatment member, an actuator (34) centrally arranged on a rear side of the handle assembly (22) and a cord reel assembly (14) arranged on a front side of the handle assembly (22). The cord reel assembly (14) includes a cord reel (30) and a cord (26) configured to be coupled to an AC power source and provide power to the suction source. The cord reel (30) is switchable between a first state, in which the cord reel (30) winds the cord (26), and a second state, in which the cord reel (30) does not wind. The actuator (34) is moveable between a first position and a second position. In response to the actuator (34) moving from the first position to the second position, the cord reel (30) switches from the second state to the first state.

  • Publication number: 20210274991
    Abstract: A vacuum cleaner comprising a housing, a suction source, a dirt collection chamber in fluid communication with the suction source, a battery to provide power to the suction source, and a plug assembly having a body and an electrical connector in electrical communication with the battery via a cord. The plug assembly is configured to receive power from an AC power source to charge the battery. The plug assembly is moveable between a first position, in which the plug assembly is outside the housing and a second position in which the plug assembly is received in the housing. When the plug assembly is in the second position, the body of the plug assembly forms an outer surface of the housing.
