Introduction
This guide addresses the removal of a malfunctioning or broken Roomba IR sensor. Roomba IR sensors measure how close a Roomba is to a wall or object and create a map of the cleaning area. The sensor can become defective when obscured with dust or lint. You will remove the exterior plates and casings of the Roomba to reach the motherboard where the sensor is attached. To reassemble the Roomba after the replacement, follow the steps in reverse.
