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.

Abstract: A hand-held surface cleaning device 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.

Abstract: A vacuum cleaner may include a surface cleaning head, a wand pivotally coupled to the surface cleaning head, and a rotatable canister mount. The rotatable canister mount may include a support through which at least a portion of the wand extends such that the canister mount rotates relative to the wand in response to the wand pivoting.
