DIAGNOSIS The docking station is issuing an audible alert, typically due to a water system error or a critical blockage preventing the robot from leaving the dock.
FIX First, check the clean water and dirty water tanks. Ensure the clean water tank is correctly seated and filled above the minimum line. Empty the dirty water tank completely and reseat it. Manually pull the robot off the dock and inspect the brush and suction inlet for large debris jams. Clear any obstruction.
IF THAT DIDN'T WORK The error may be related to the internal pumps. Check the small filter inside the clean water tank's connection port on the dock for clogs. Perform a manual mop wash cycle from the app to see if water flows correctly. A persistent beep often correlates with error codes 1 or 3 in the app's notifications.
HEADS UP The dock's beeping will not stop until the triggering condition is resolved. Always use the official cleaning solution or plain water; third-party solutions can cause pump clogs and sensor errors.
