This is a great little vacuum for the price! It is very powerful and the suction is incredible. I have a dog and two cats and this lightweight machine does an excellent job of getting these hairs off the carpet. It also only has only one filter to clean and this can be done by shaking it out every time you empty the waste cup. The manufacturer recommends replacing it every six months but it really only needs to be shaken out and occasionally "hosed" down in the sink.
