  • Publication number: 20200046184
    Abstract: A cleaning apparatus may include at least one isolator configured to absorb mechanical vibration generated by contact between an agitator and a combining unit to reduce noise and/or vibration. The isolator may include at least one combing isolator disposed at least partially between the combing unit and the surface cleaning head. Alternatively (or in addition), the isolator may include a panel isolator disposed at least partially between a housing of the cleaning apparatus and a panel.

  • Publication number: 20200000298
    Abstract: An example of a vacuum pod may include a handle, a vacuum pod body, a dust cup removably coupled to the vacuum pod body, and a fluid conduit fluidly coupled to the dust cup. The fluid conduit may include a flexible hose configured to transition between an expanded and a retracted position and a coupling configured to be removably coupled to the vacuum pod body. A first end of the flexible hose may be coupled to the vacuum pod body and a second end of the flexible hose may be coupled to the coupling. When the coupling is coupled to the vacuum pod body, the flexible hose may be in the retracted position.

  • Publication number: 20190274501
    Abstract: A vacuum cleaning apparatus may include a debris container and a filtering system. The debris container may define a debris collection chamber and include a dirty air inlet and a clean air outlet. The filtering system may be at least partially disposed in the debris collection chamber, and may include a fluff screen and a fluff screen cover defining a cavity for receiving at least a portion of the fluff screen. The fluff screen and the fluff screen cover may both include tapered outer surfaces. The tapered outer surfaces may have opposing tapers.

  • Publication number: 20190060812
    Abstract: A surface cleaning apparatus having an air flow path from a dirty air inlet to a clean air outlet and including an air treatment member, a suction motor and a filter assembly in the air flow path. The filter assembly includes at least two spaced apart physical filter elements with the upstream face of the second filter facing the downstream face of the first filter element. The filter assembly is configured to prevent air from bypassing the first physical filter media. The filter assembly includes a gap between the first filter element and the second filter element that acts as a header and reduces the flow rate of air incident on the second filter element.

  • Publication number: 20180338656
    Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.
