1. A surface-cleaning apparatus for cleaning particulate material from a moving surface in an electrographic printer, the surface-cleaning apparatus adapted to contact a surface of the moving surface and to remove particles from the surface to deposit the particles into a sump comprising:
(a) a lower bracket assembly for releasably supporting the surface-cleaning apparatus comprising one or more wiper blades;
(b) a backup shoe assembly including a shoe having a hard surface adapted to contact the surface opposite that contacted by the one or more wiper blades and to resist the force exerted by the one or more wiper blades;
(c) one or more springs located between the sump and the lower bracket assembly to align the sump with the shoe;
(d) a web cleaning device having sides including one or more lips and defining a cavity, and one or more molded components, the web cleaning device comprising one or more stops are located on a side lip so that the one or more springs can bias the one or more stops to the shoe to reduce the tolerance between the one or more wiper blades and the surface; and
(e) a cover assembly to facilitate the removal of the particulate material from the sump without removing the one or more wiper blades.
