This is the third Shark vacuum that I've bought and I won't buy any other brand.  I love the Shark Rotator...the vacuum can be maneuvered in corners and tight spaces.  And so powerful!  I was amazed at the amount of dirt it picked up.  I have long hair and hair sheds, so knowing the vacuum won't get any hair stuck in the rollers is wonderful!  No more turning the vacuum upside down an using scissors to cut out the hair.  What a drag that was.  I also love that I can "lift away" when necessary...that makes it easy to vacuum stairs or even the ceiling.  This is a product!  Keep up the good work!
