Abstract
A parts cleaning device has at least one rotor assembly with an axis of rotation, and a plurality of microfiber cloths arranged at spaced locations along a length of each rotor assembly. The microfiber cloths each have an opening through a center portion thereof, and a shaft of the rotor assembly extends through the opening. A plurality of spacers are arranged so that each microfiber cloth is squeezed between two spacers. The rotor assembly is rotated together with the microfiber cloths so that centrifugal forces cause the microfiber cloths to extend radially outwardly from the rotor assembly and wipe surfaces of parts that pass within a path of movement of the microfiber cloths. A vacuum chamber has an inlet positioned in the path of movement of the cloths for removing fine particles from the cloths as the cloths rotate past the inlet.
