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 detachable assembly having multiple adjustable components is provided for folding various materials, such as a sheet of disposable wipes. In one embodiment, the assembly includes an attachment bracket configured to detachably connect the assembly to a structural member, a roller, a feeder plate having a return flange, and a folding bracket. In another embodiment, the assembly includes a mounting bracket having at least one hook configured to detachably receive the attachment bracket. In a further embodiment, the feeder plate is formed from two tapered halves which are slideably connected. In use, a material is a fed over the roller, down along the feeder plate, and then forward along the return flange where the folding bracket folds the material inward over the return flange. The user may adjust the position of the feeder plate and the folding bracket to achieve the desired fold width in the material.
