Light rubber main brush failed after about 3 uses. The outer surface came off the axle and Roomba didn't lift anything further. I took it apart to see what was wrong - the rubber connecting the outer surface to the axle was torn. Luckily I kept my original brush which has faded but still works. Not sure if it's just bad stuff or if it was already damaged before I received it. The original brush lasted a few years. I only replaced it with this one because the darker brush needed replacing. Not very impressed with the amount of service I received from this brush.
