Query: Good at first, bad later.

We bought a hoover savy of this type about 2 years ago and were very happy with the device at first. Then we started having problems with the switch. Almost like there was a short in it. The main vacuum wouldn't fully engage. We finally took it to a repair shop, and in short order found out the part was on back order. I promptly emailed Hoover with my problem in which i received a response with a phone number for another parts dept. This didn't help at all. To me it seems hoover dosen't keep its parts on order in order to have you buy a new vacuum. I will however never be buying another hoover product again.
