Review on 🧹 Neutop 2 Sets Multi-Surface Rubber Brush Roller Replacement Parts for iRobot Roomba 800 900 Series - Enhance Your Robot Vacuum with this Replenishment Kit Accessory by Paula Pickett

Well, these things aren't perfect and didn't work at first. This is either a quality control issue or a manufacturing issue. But I found a solution, at least for the ones I bought. After I put them in Roomba they seemed fine for a minute or two, then Roomba stopped and said something was stuck. I took it out, checked, found nothing, plugged it back in and Roomba started again but stopped again with the same message. After many tries and almost ready to return it, I figured out what the problem was. These pieces are miscut, mostly gray and black (soft) plastic rolls are cut unevenly and may be too long. So I took a pair of scissors and cut them off a few millimeters (on the opposite side of the yellow end). They weren't quite even, but fairly short around the entire circumference. Plug them in and now Roomba is working fine. It's been working fine for a few days so far. I will update this if anything changes.
