I got the Shark Lift-Away with powerfins Hair Pro and Odor Neutralizer Technology Upright Vacuum in the mail about 1 year ago. I use it every single night because we have 5 cat's and 3 dogs running around our 1 story house. Our dogs don't shed, its more the cats. This vacuum is very powerful. Its so easy to maintain. I love that it has the Odor Neutralizer and it smells amazing. I replace it every 6 month's. Its a self cleaning brushroll. You can take the life away off the sweep and clean little corners or take the handle and get up high on the ceilings. I won't ever get another sweeper other than a shark!
