Perfect fit for my Lift-Off Pet Cyclone. I'm not sure why these rollers are killing vacuum cleaners, but I'm glad I found a replacement. The last video made a loud noise that got progressively worse over time. Looking at the Bissell websites and the vacuum cleaner manual, they mentioned that it is advisable to replace the roller every 6-12 months. Obviously the brush wears out and becomes less efficient. Overall a cheap replacement!
