iRobot Roomba S9+ Repair Manual

Symptoms

The same rooms now exhaust a full charge far earlier than the owner baseline.
The robot runs normally but the charged battery lasts far less than a typical job.
The robot charges fully, but ends early with low battery, repeatedly recharges, or cannot reach the Home Base before Error 46.
The correct wet or damp cycle leaves pooling or substantially more water than expected.
The robot cancels a mission for a navigation problem or ends somewhere other than the Home Base after route and map state are ruled out.
The tank is filled to the top and installed flat, but the red sweep or Error 37 still says to fill it.
The robot refuses charge because the pack temperature is outside normal range.
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 robot drives and sprays, but the cleaning head lacks its normal scrubbing vibration with a wet pad.
The Clean Base has no status response or cannot pass charge to the robot.
The battery will not insert fully, click into place, remain retained, or release normally.
The robot moves, but one wheel makes repeatable noise or feels rough through rotation.
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.
The robot wakes but the battery level does not rise on the Home Base, or the app announces a charging error.
The robot is charged but cannot drive off the Home Base when a job begins after clearance and placement are proven.
The job ends with a docking problem or the robot cannot find the Home Base after placement, clearance, and map-start checks are corrected.
The robot repeatedly reverses, circles, or turns away on a clear, level hard floor after placement causes are ruled out.
The Clean Base still reports a bag condition after the owner checks the bag.
