A paint brush comprises an elongate handle having a proximal end and a distal end, a tuft of bristles having properties according to at least two distinct directions, and a ferrule. The bristles are arranged substantially parallel to an axial direction and the cross section of the tuft of bristles is in a plane that has a width in a lateral direction. One end of the handle is operatively associated and is in substantially longitudinal alignment with the tuft and the ferrule is adapted to surroundingly encircle and connect said handle to said tuft of bristles so as to support the bristles against splaying in the lateral direction and limit deflection of the width.

A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

An oral care implement comprises a first and a second part. The first part has a carrier plate having a back side and a front side opposite the back side, and at least one cleaning element extending from the front side. The second part has a support plate and at least a portion of a neck, the support plate having a front side and a back side opposite the front side. The back side of the carrier plate is secured to the front side of the support plate by means of a plastic material molded around at least a portion of the back side of the support plate and over at least a portion of the carrier plate to provide a non-detachable connection between the first and the second part.
