Abstract
An endless elastomeric vacuum sweeper belt for use in a vacuum sweeper having a diamond pattern drive surface. A first set of ribs project inwardly in a substantially diagonal direction along the drive surface of the belt. A second set of ribs project inwardly along the drive surface of the belt in a substantially diagonal direction opposite the direction of the first set of ribs. The first and set second set of ribs together define a diamond-like pattern on the drive surface as well as a number of particle recesses for the temporary collection of matter. Each rib includes knife-like edge portions to increase the traction of the belt on a drive surface by cutting, loosening and expelling foreign matter lodged between the belt drive surface and the rotation member and/or the drive source of the vacuum sweeper.
