Bests & Worsts Reviews from Amazon

I bought this vac for my wife on March 23rd, 2013 and today (about 4 1/2 months later) it goes to the trash can. It worked well until about a month ago when it started going through belts. Today, my wife told me it had been smoking when she used it (I thought it's too young to be smoking). Being an engineer, I took this as a challenge and decided it was time to get to the bottom of it. I ran the vac with the bottom cover removed and observed that the belt migrates over to the end of the motor shaft and begins rubbing on the metal rub plate. I wondered why the belt moves off the center of the motor shaft. A close look revealed that the motor shaft is no longer parallel to the beater brush. I suspected something had slipped out of place inside the motor housing so I unplugged it and took it apart to see if I could fix it. As I was taking it apart I noticed that the plastic housing surrounding the motor shaft was deformed from excessive heating. In fact, after about fifteen minutes of disassembly time, the motor was still too hot to touch. At that point I realized there was no fixing this. They've taken too much cost out of the motor (not enough iron and copper) which makes the motor run too hot which in turn softens the plastic housing causing it to deform. It's a shame, if they had spent about five bucks more on the motor it would have lasted for years.
