I had a vac. that was always getting clogged with dog hair. I bought the Shark and I love it. I have had it a month and vaccum daily, it has not clogged once. ( I sweep up a mini Labadore Ret. daily.) The power is so strong that it lifts the carpet up. I also love the fact that the canaster comes off the floor attachment and makes it easy to use on stairs and when cleaning the car. I t also turns like it is on a ball, this makes it easy to get around the legs of furnature. It is sold at Bed Bath and Beyond. With their 20% off coupon it makes it really reasonable in cost.
