Robot vacuum reports E10 and cannot find or return to the charging dock.

Safety: Keep the robot powered but do not place fingers on the charging contacts while plugged in.

• Step 1 – Clean IR windows: On the front of the robot and the dock, locate the dark plastic windows used for IR communication. Wipe them with a soft, dry cloth.
• Step 2 – Reposition dock: Place the dock against a wall with at least 0.5 m (1.5 ft) clear space on both sides and 1.5 m (5 ft) clear in front. Avoid direct sunlight or mirrors facing the dock.
• Step 3 – Test return-to-dock: Start the robot a few meters away and press the Home button (on robot or app). Observe whether it detects and approaches the dock.
• Step 4 – Check dock power: Ensure the dock’s indicator light is on. Try another outlet if necessary.
• If E10 persists: The IR receiver module or associated circuitry on the robot may be faulty and require replacement.
