Robot vacuum does not return to the charging base and stops in random locations with low battery.

Safety first: Keep the area around the dock clear to avoid tripping hazards.

• Step 1 – Reposition dock: Place the Medion charging base against a straight wall with at least 0.5 m free space on each side and 1.5 m in front.
• Step 2 – Clean dock and robot sensors: Wipe the IR windows on the dock and the front of the robot with a soft cloth.
• Step 3 – Test homing: Start the robot near the dock and press the home/return button. Observe if it detects and approaches the dock.
• Step 4 – Check dock power: Ensure the dock’s LED is on and the adapter is working.
• Step 5 – Replace dock or sensor: If the robot consistently fails to see the dock, replace the Medion charging base or the robot’s dock detection sensor board as needed.
