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: An exercise apparatus includes an elongated outer elastic hollow tubing having opposed ends and an elongated inner elastic hollow tubing having opposed ends. A connection mechanism at each of the opposed ends is for interlocking the respective opposed ends of the elongated outer elastic hollow tubing and the elongated inner elastic hollow tubing. A pair of handles is positioned at respective opposed ends of the elongated outer and elongated inner elastic hollow tubings.

Abstract: A therapeutic roller apparatus that includes a rigid plastic roller member and a soft foam material sleeve that is adapted to fittingly mount about the rigid plastic roller member. The rigid plastic roller member preferably also has an inner tubular passage for fittingly receiving a vibration assembly. The vibration assembly includes, inter alia, an energy driven motor, preferably driven from an array of batteries and a weight that is coupled with the motor. The weight and motor together, when operated, provide a vibratory effect that is transferred through to the outer soft foam material sleeve.
