This is our second shark vacuum. And we are now super fans. We really liked our first one so when it came time to replace it we went back to shark. This new model that is self cleaning is amazing. I have a dog that sheds a lot, so does my wife, I swear I was cutting her hair off the brush all the time.  It is not completely eliminated but on this vacuum it is SIGNIFICANTLY less. This vacuum out performs other vacs that cost twice as much!
