Great performing vacuum for pet hair on carpet. Unfortunately the brush assembly end caps that hold the metal brush "axle" are all plastic and we've had two of these model vacuums wallow out the end cap axle receiver hole in only 12-15 months. Of course you have to buy the entire brush assembly and can't just buy the defective end caps. The end caps need to have a metal insert to stand the offset pressure of the off center belt. This key component is poorly designed!
