At first I was so excited that the vacuum cleaner picked up all the cat hair! It's true, it was very strong and worked well. But the cat hair would clog in the roller and it was time-consuming and hard to pull it out. Also the filter is hard to clean and would take days to dry. Then after a year (almost 2 weeks after the warranty expired) it stopped sucking. So now it's just sitting in my closet, useless, until I have time to go have it fixed.
