I had just about finished vacuuming my whole house when my old vacuum went kaput. When this arrived two days later I tested it my living room and ended up revacuuming my whole house, Having to empty the container after each room because it was picking up so much my other vacuum didn't. I couldn't believe the amount of cat hair it got. I also love that it came with the extra filters so you can still go about cleaning when you have to clean out the others. Great vacuum!
