iRobot Roomba S9 9150/S9+ OEM Original Robot Cliff Edge Drop Sensor with plastic retainer. This is a sort of hinged piece that needs to rotate out of the way for a wheel replacement. Frequently broken. Clean and from units with low hours of use. Very nice set. These are for the older units with the plug for each sensor. If you have a newer unit that uses a single connection for each side, you can use this to replace the broken plastic only. Free continental USA shipping. Calculated for outside USA.
