Bests & Worsts Reviews from Amazon

I am having real problems with this purchase. The beater brush is driven by a rubber belt using a one eighth of an inch diameter drive shaft driving the rubber belt to a one and a quarter inch diameter brush roller.If there is any resistance on the brush roller then the rubber belt stops and the small diameter shaft wears a depression in the drive belt and in any subsequent use the drive pin will no longer drive the beater brush.I have replaced the drive belt three times and still experience the same problem.We have a normal home with hardwood floors in the kitchen area and low pile carpeting elsewhere. Apparently this hoover is not designed for a normal home.
