I have used a Dyson for the last 15 years. Last month I decided to try this vacuum given the good reviews. The biggest issue I have is that the chord is too short. the 2nd biggest issue is that the chord is splitting. While making sure the vacuum does not run over the chord is the end goal it must have at one time run over a part of the chord and not it's exposed. In all the years Iv'e had a dyson this had never happened to our chord. The chord is so much thicker- something I really appreciate it. I've been trying to contact Shark but I can't seem to get through, will try early one morning while at work. 

Other than that, yes it does a lot better on hard wood floors than dyson. Also I love the self cleaning brush-roll.  

Hope to get the chord issue addressed soon!
