After we went through about 3 vacuums in 2 years of living in our apartment with our 4 cats, my husband surprised me with this vacuum for Christmas. It's amazing. I vacuumed the apartment and had to empty the canister 4 times! It picked up so much of the dirt and cat hair that the previous vacuums had left. It runs smoothly, but is very powerful, and our carpets look amazing after they are vacuumed. The couch attachment works very well too, and the extending handle makes it easy to clean hard-to-reach areas, as well as get to cobwebs on the walls and ceilings. Suction Performance It's true! It never loses suction!
