Robot vacuum reports E11 and cannot find or dock with the charging base.

Safety: Keep liquids away from IR windows.

• 1. Reposition dock:
  • Place the dock against a wall with at least 1.5 m (5 ft) clear space in front and 0.5 m (1.5 ft) on each side.
  • Avoid direct sunlight or mirrors facing the dock.
• 2. Clean IR windows:
  • Wipe the front of the dock and the robot’s front sensor window with a soft, dry cloth.
• 3. Manual docking test:
  • Place the robot about 1–2 m (3–6 ft) in front of the dock and press the Home/Dock button.
  • Observe if it detects and approaches the dock.
• 4. Check dock power:
  • Ensure the dock LED is on; if not, test another outlet or adapter.
• 5. If E11 continues:
  • The IR receiver board or dock emitter may be defective; replace the dock first, then the robot’s IR receiver module if needed.
