Query: Hoover Windtunnel V2 poor performer

Purchased five months ago, 08/25/2002. Have a dog with medium length hair and a wife that sews occasionally. Hair and thread wrap around the cheap and poorly engineered plastic bushings designed to protect agitator bearings from wearing and debris. Bushings have dissolved away and agitators no longer spin. You would be wise and buy a better designed brand or be prepared to disassemble and clean bushing and bearings frequently...A useless vacuum to me and only for dust pick-up.
