ABSTRACT:
A sanding machine with a hand held sanding unit connected to a base unit, containing one motor that has several purposes: to provide suction of debris back to the base unit through a hose, to power a driver cable that rotates the hand-held unit and to produce vibrations needed to cause the filters to release accumulated debris, whereby three motors are not necessary as in my prior U.S. Pat. No. 6,315,647 issued on Nov. 13, 2001.
