This package includes (2) flat belts specifically designed to work onThe Bank President & The Bank Super Smooth upright vacuum cleaners. These belts are made from a better rubber compound to insure long life and consistent brushroll speed for better performance. We recommend changing your Bank President and Bank Super Smooth vacuum belt every 6-12 months to insure proper brush speed. Even if you don't believe the belt is worn do not let your belt go more than 12 months. These belts are friction driven and the constant tension causes the belts to loosen over time.
