Query: what a horror!!!

WE bought this machine to clean our spiritual center where the 1600 sq feet are all carpet, little furniture. We wanted something self propelled because of the open expanse of floor. It cleaned well for the first few times and then began to growl, and finally the motor exploded in a shower of sparks and awful smell. It was 4 months old. Since it was under warranty we could get the motor relaced, which took 6 weeks. It then worked Ok for about a year and just recently the on/off switch died and it turned on only when it was plugged in. Just last week it exploded again, and would'nt you know, the warranty had expired! The vaccum repair man said it would be cheaper to buy a new vacuum. I guess it will be no more hoovers. Too Bad!
