Abstract
A marginal floor brush spacedly surrounding the rim of a chambered sanding machine base. The brush meets the floor and confines wood dust developed by a rotary sanding unit in the base. The dust is drawn from under the brush by a vacuum unit in the machine. This is facilitated by disposing the brush floatingly free of the machine to stir up and separate the dust particles and leave the floor clear of dust as the machine moves on.
