Yeah, this one's common—it's a designed timeout, not a defect. After 90 minutes of inactivity off the charging station, it automatically ends the cleaning job to conserve battery.
FIX: If it stopped because the job was genuinely incomplete, just send it out again. Make sure it starts from the charging station so it can return to recharge if needed.
- Check if the tank is empty. If the light ring showed a red sweeping motion, it stopped to get refilled. Fill the tank and press CLEAN to resume.
- If the battery was low, it should have returned to charge. If it didn't, place it on the charger manually. It'll resume where it left off once recharged if the 'CLEAN' text is pulsing.
IF THAT DIDN'T WORK: For very large areas, the robot might be struggling to map it in one session. Use the iRobot HOME App to adjust cleaning preferences for speed and coverage, or clean the area in sections.
HEADS UP: Your robot works best with the iRobot HOME App. Use it to customize cleaning power and water spray amount, which can help optimize cleaning time.
