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.

A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener. The tufting tool includes a notch. The method provides a brushroll with bristles tufted into the bristle hole adjacent the bristle stiffener. A brushroll for a vacuum cleaner can be made using an injection molding process, with bristle stiffeners integrally molded with the dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

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.

The present invention relates to the skin cleansing device with plurality of cleansing element, wherein the plurality of cleansing element comprises plurality of microfiber element. The plurality of microfiber element absorbs the pollutants from the tiny pores of the user skin and prevents the scattering of the pollutants from the tiny pores onto the user skin. The present invention also eliminates the need of using any harmful cleansing lotion during the skin cleansing process as it enables the user to just moisturise the plurality of microfiber elements with water for absorbing the pollutants.

The present invention provides a cylindrical brush assembly designed for precision cleaning of circular wafers and delicate surfaces. The brush features polyvinyl alcohol (PVA) nodules of varying lengths along one side of a cylindrical core, enabling conformity to changing gap sizes when applied at an angle to the wafer. This ensures consistent contact and uniform cleaning across the entire surface. A modular design with replaceable nodule holders allows for easy customization and maintenance. An integrated RFID tracking system embedded in the end cap monitors usage and wear levels in real time. The cleaning method involves rotating the brush at an angle relative to the wafer surface, with the nodules adapting to surface contours for optimal efficiency. While tailored for semiconductor wafer cleaning, the assembly is adaptable for other industrial applications requiring precision cleaning.
