We have been extremely happy with our Shark Navigator. It is easy and light enough for our kids to us. I also really like the rotating neck that helps to get into hard to reach places. We have a black lab and it keeps up with all the pet hair as well. The filter is easy to take out and wash. I also like the fact that it is bagless and not messy to dispose of dust and hair. For the price we are very happy with our purchase from 4 almost 5 years ago and have had no problems so far.
