Neato XV-21 XV-14 XV Pro etc for All XV series Lidar O-Ring Replacement

This is for the rubber O-Ring (drive belt) that connects the Neato XV-21 motor to the Lidar unit.

The rubber O-Ring that comes with your Neato XV-21 will get old/dry then snap, resulting in the lidar unit not working. This will show up as, "error 3000" on your Neato LCD screen. Sometimes the error 3000 is because of a broken motor, a broken lidar unit, or if you're fortunate, only a broken o-ring. A broken o-ring is a cheap fix compared to other issues.
