iRobot Roomba S9+ Repair Manual

Symptoms

Home is requested, yet the robot misses the Clean Base or will not settle.
The robot is charged but cannot drive off the Home Base when a job begins after clearance and placement are proven.
The robot wakes but the battery level does not rise on the Home Base, or the app announces a charging error.
The top lid stands proud, will not latch, or the robot reports Error 45 when a job starts.
The robot will not start, or stops after a pad falls off, and reports three beeps.
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 charges fully, but ends early with low battery, repeatedly recharges, or cannot reach the Home Base before Error 46.
The Clean Base has no status response or cannot pass charge to the robot.
The robot cannot sense or drive the left wheel, announces Error 7, pulls right, or stops at startup.
The robot drives and sprays, but the cleaning head lacks its normal scrubbing vibration with a wet pad.
The 200-series robot is awake nearby, but the iRobot app cannot add or connect to it.
The robot approaches an actual stair, ledge, landing, balcony, or raised edge.
The robot repeatedly reverses, circles, or turns away on a clear, level hard floor after placement causes 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 drill runs steadily but drills slowly or cannot drive a normal fastener with correct setup.
The robot is trapped, tilted, moved, or unable to continue a clear path.
The correct wet or damp cycle leaves pooling or substantially more water than expected.
The robot refuses charge because the pack temperature is outside normal range.
The pad no longer lies flat and interferes with smooth travel.
The robot moves, but one wheel makes repeatable noise or feels rough through rotation.
