  • 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. 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.

  • Patent number: 11278171
    Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) 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 rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

  • Patent number: 11039722
    Abstract: In general, the present disclosure is directed to a force-sensing arrangement for use in surface cleaning devices, such as a vacuum device, that allows a user-supplied force to be translated into a command signal to cause the surface cleaning device to accelerate forward, reverse or to veer/turn in a desired direction. In an embodiment, the surface cleaning device includes a nozzle, wheels, motor(s) to drive the wheels, and an upright handle portion. The surface cleaning device includes a force-sensing arrangement with load cells coupled at a position where user force is transferred from the upright portion to the nozzle. The force-sensing arrangement detects the user supplying a relatively small amount of force and translates the same into measurement signals. A controller coupled to the load cells utilizes the measurement signals to determine or “infer” a desired direction of travel.

  • Publication number: 20190320866
    Abstract: In general, the present disclosure is directed to a hand-held surface cleaning device that includes circuitry to communicate with a robotic surface cleaning device to cause the same to target an area/region of interest for cleaning. Thus, a user may utilize the hand-held surface cleaning device to perform targeted cleaning and conveniently direct a robotic surface cleaning device to focus on a region of interest. Moreover, the hand-held surface cleaning device may include sensory such as a camera device for extracting three-dimensional information from a field of view. This information may be utilized to map locations of walls, stairs, obstacles, changes in surface types, and other features in a given location. Thus, a robotic surface cleaning device may utilize the mapping information from the hand-held surface cleaning device as an input in a real-time control loop, e.g., as an input to a Simultaneous Localization and Mapping (SLAM) routine.

  • Publication number: 20170347848
    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.
