  • Publication number: 20220110495
    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.

  • Patent number: 11284702
    Abstract: A robot cleaner including a body, a driven wheel, and a side brush coupled to the body. The side brush includes a hub configured to rotate about a pivot axis and a plurality of bristles. Some bristles may form a first angle with the pivot axis and others form a second angle with the pivot axis which is larger than the first angle. Some bristles may have a first bristle length and others have a second bristle length which is larger than the first bristle length. The robot cleaner may include a side brush deflector to deflect debris propelled by the side brush towards the vacuum inlet. The side brush deflector includes a plurality of deflector bristles extending downwardly from a floor facing surface of the robot cleaner towards a floor such that some of the bristles pass through or underneath a portion of the deflector bristles.

  • Publication number: 20220031133
    Abstract: An agitator including an elongated main body configured to rotate about a pivot axis, one or more soft cleaning features coupled to and extending over a substantial portion of a surface of the elongated main body, the one or more soft cleaning features defining at least one channel, and at least one deformable flap disposed at least partially within the at least one channel and extending from the elongated main body. The deformable flap may extend beyond an outer surface of the soft cleaning features. The channel may have a generally U shape and/or V shape. The channel may be configured to allow the resiliently deformable flap to move front to back as the agitator rotates about the pivot axis.

  • Publication number: 20210177223
    Abstract: A nozzle having castellations provides high suction pressure while also allowing for large pieces of debris to pass through inlet openings. In more detail, a nozzle for a surface treatment/cleaning apparatus is disclosed herein. The nozzle provides a suction channel through which debris passes into a main body of the surface treatment apparatus. Castellations are provided along a leading edge of the nozzle to allow debris to pass through the leading edge to the suction channel, and into the main body during, for instance, forward and reverse strokes of the surface treatment apparatus. In an embodiment, the castellations further include receptacles/cavities to receive and securely hold wheels therein. The wheels may extend from the nozzle at a predefined angle, also referred to herein as a camber angle, to improve vacuum handling and reduce noise during operation.

  • Publication number: 20200329930
    Abstract: A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators 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 brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.
