ABSTRACT:
An apparatus for cleaning particles from a surface including a conductive flexible brush belt having a piezoelectric exterior layer to which is attached conductive brush fibers which contact the surface to be cleaned. A support member, about which the belt is entrained, provides sufficient deformation to the belt to cause a voltage to be developed on the surface of the piezoelectric exterior layer in response to being deformed. The voltage causes particles to adhere to the conductive brush fibers. The particles are removed from the brush fibers at a detoning station.
