As of 2004, Sharp stopped producing vacuum cleaners, as indicated by Vacuum-Outlet.com. Consumers can still find vacuum bags and belts on the market for those who had bought the vacuums before.
One can still find Sharp vacuum cleaners on the Internet on sites such as eBay, but these are leftovers or models that have been refurbished, as stated by Info-Vacuum-Cleaner.com.
The Sharp website still has information on how to conduct various repairs on vacuums that had been produced by the company and also offers parts, including vacuum bags. It is less likely, however, for one to find any parts from retail stores.
