<p>An apparatus (50) for cleaning particles from a surface, which includes a magnetic transport (52, 54) for moving a cleaning material into contact with the surface. The magnetic transport (52,54) is electrically biased to a polarity and magnitude sufficient to attract the particles from the surface to the cleaning material. An electrically non-conductive member (62), positioned closely adjacent to the magnetic transport (52, 54), is electrically biased to the same polarity as the magnetic transport (52,54) with the magnitude thereof being greater than the magnitude of the electrical bias applied to the magnetic transport (52,54). In this way, particles adhering to the cleaning material are attracted therefrom to the member (62).</p> |
