Review on 🔍 2-Pack Jorllina Rolling Brush Replacement Parts for Eufy RoboVac 11S, RoboVac 11S MAX, RoboVac 30, RoboVac 30C, RoboVac 15C Robotic Vacuum by Emily Armstrong

I'm not sure if the bearings in this product are sealed at all. While the original brushes lasted several months before the bearings became clogged with dirt, the brush became more difficult to turn. They were harder to turn and very quickly clogged with mud. Each brush only lasted a few days in vacuum before the bearings became very difficult to turn. Will try another 3rd party replacement for next batch.
