Shop for Riccar Vacuum Cleaner Belts at Vacuums Unlimited and save big. Riccar vacuum cleaner belts are in stock and ready to be shipped. The vast majority of Vacuum cleaner belts are made of rubber, so they will stretch and wear out over time. The belts run the brush rolls thousands of revolutions per minute, so the tighter or newer the vacuum belts, the better the vacuums perform. For optimum performance replace belts every 12 months.
