I just received my vacuum yesterday and couldn't wait to try it out.  I love the powerfins and the soft, self cleaning brushroll.  It does a great job!  My old vacuum is a Shark Professional Lift Away, I loved it but it was time for a new one.  I love this one even more.  The beater brush on my old machine is noisey going across my wood floors and always had hair wrapped around it.  This new model is much smoother and quieter going across my wood floors.  Great Suction and I love all of the tools that came with it.   I do think these vacs are a little pricey and for the price it would be nice if they included a couple of extra filters.
