A replaceable brush head includes an upper surface, an outer perimeter edge, and a plurality of tufts. The upper surface includes a plurality of bristle tufts. The lower surface includes an outwardly extending knock-out button. The outer perimeter edge includes at least one protrusion. The replaceable brush head may be installed in a toothbrush body that includes a head portion having a recess sized to fit the replaceable brush head with a knock-out opening for the knock-out button and at least one channel for coupling to the at least one protrusion. The replaceable brush head can be removed from the toothbrush assembly by applying a force to the knock-out button in the direction of the tuft plate.

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.
