Absolutely the best vacuum cleaner I have ever owned (and there have been a few). I have always been a bit of a vacuum snob, choosing the "no loss of suction" brand. With 3 dogs, 2 regularly shedding indoor huskies and a terrier and I did an experiment, after vauuming over an area with my "no loss of suction" vaccum I then tried the Shark and it was an amazing, apart from so much more dirt and hair the Shark seemed to lift the pile. I don't work for Shark and get nothing from this review, but it really is a fantastic vacuum.
1 negative, no retractable cord.
