Symptoms

The chassis moves beyond a true floor edge instead of backing away.
The robot repeatedly reverses, circles, turns in place, or drifts instead of following a stable path.
The two blue-line mode activates, but the robot travels beyond the intended invisible boundary.
The robot halts on a safe flat floor as though a drop were present.
The robot moves, but one wheel makes repeatable noise or feels rough through rotation.
The correct wet or damp cycle leaves pooling or substantially more water than expected.
The robot repeatedly reverses, circles, or turns away on a clear, level hard floor after placement causes are ruled out.
The 200-series robot is awake nearby, but the iRobot app cannot add or connect to it.
The pad no longer lies flat and interferes with smooth travel.
The pass count or spray behavior does not match the installed wet, damp, or dry pad.
The robot drives and sprays, but the cleaning head lacks its normal scrubbing vibration with a wet pad.
The corner brush stops, loosens, wobbles, or leaves edge debris behind.
The robot reports four beeps immediately after an attempted start.
The robot will not start, or stops after a pad falls off, and reports three beeps.
