Hoover WindTunnel Canister Vacuum, Electronic Bagless, S3765-040This is my second Hoover Wind tunnel of this model number. I bought it for its excellent dirt and dog hair removal. Neither one has lasted long before the power head shuts off when running or parts begin breaking making it too difficult to continue using,My last one has not lasted 10 months! I did take a chance ordering the 2nd as the reviews were not that positive for reliability. Now I feel strongly enough to give it a poor review
