  • Publication number: 20240145991
    Abstract: An outlet module mounting mechanism for use with a power distribution unit including: a bracket attachable to an outlet module; a latch movably coupled to the bracket, wherein the latch has a proximal end portion and a distal end portion; a link coupled to the proximal end portion of the latch; and a plunger connected to the link and movable between a released position and a latched position. When the plunger is moved to the latched position the plunger moves the link away from a front side of the outlet module such that the distal end portion of the at least one latch moves toward the front side of the outlet module to engage a corresponding wall of the housing thereby securing the outlet module to the housing.

  • Publication number: 20240057839
    Abstract: A flexible flap coupled to the bottom of a cleaning tool is designed to have a distal end that contacts the floor and scrapes along the floor as the cleaning tool is moved across the floor in order to help guide debris into a catch tray. The flexible flap also has a design such that the distal end can curl inwards after interaction with an obstacle (e.g., recess or protrusion of the floor surface) and continue to move across the floor picking up debris, even after the distal end of the flexible flap has been curled.

  • Publication number: 20240008701
    Abstract: A door opening mechanism is operable by an actuator (1140) to open a dirt chamber door (1070) to a dirt collection chamber (1066). The door (1070) is movable about a pivot (1072) between a closed position and an open position. In some examples, the actuator (1140) may be located on the same side of the dirt collection chamber (1066) as the pivot (1072). In some examples, the actuator (1140) may be positioned vertically higher than the pivot (1072) when the dirt collection chamber (1066) is in the emptied position.

  • Patent number: 11712139
    Abstract: A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

  • Patent number: 11051668
    Abstract: A vacuum assembly having a hand vacuum configuration and a wand vacuum configuration may include a dust cup, a suction motor fluidly coupled to the dust cup, and a power source. The suction motor and the power source may be transitionable between a wand vacuum position and a hand vacuum position. When the suction motor and the power source are in the wand vacuum position, the dust cup, the suction motor, and the power source may be arranged serially. When the suction motor and the power source are in the hand vacuum position, the suction motor and the power source may be arranged in parallel with the dust cup.
