I got the Shark® Rotator® Lift-Away® ADV Upright Vacuum with DuoClean® PowerFins™ and Self-Cleaning Brushroll, and have been using it for about 2 weeks now.  I got this style because I have multiple pets and a lot of pet hair. This vacume is amazing! This is my first "fancy" vacume. Before I had always had used your traditional upright, bag, blowing the belt vacuum's,  so when I first used the Shark I was shocked really on how good the suction was and how well it picked everything bit of hair and dust. I also love the fact you can detach the tank and carry that part around with you and get to all the "hard to reach" areas. Overall I am hooked! Never will I go back to the big, clumpy vacumes. I'm sold on Shark and definitely recommend their products! Expecualy their vacuumes.
