This was a great vacuum for 3 years. Then it started giving me power connection issues. The hose lost power first then the whole thing a few weeks later. My vacuum repair guy said that he sees this problem with all Windtunnel vacuums. The Hoover Windtunnel Canisters have a life span of 2-3 year WindTunnel Technology uses computer designed air ducts to provide a powerful dual air stream to enhance dirt pick up capabilities. The WindTunnel design also reduces the scattering of debris common to many ordinary canisters. The WindTunnel Bagless Power Nozzle Canister picks up more dirt than any other canister...period!
