Robot vacuum reports 'Error 19' / voice prompt 'Error 19: Docking error' and cannot return to the charging dock.

Safety first: Keep the dock plugged into a safe, dry outlet and do not open the dock while powered.

• 1. Reposition the dock:
  • Place the dock against a wall with at least 0.5 m clearance on each side and 1.5 m in front.
• 2. Clean IR windows:
  • Wipe the front of the dock and the front sensor window of the robot with a soft cloth.
• 3. Test manual docking:
  • Place the robot 1–2 m in front of the dock and press the Home button.
  • Observe if it can see and approach the dock.
• 4. Check dock power:
  • Ensure the dock LED (if present) is lit, indicating power.
• 5. If the robot cannot detect the dock at all:
  • The dock IR emitter or robot IR receiver may be faulty; replace the dock or front IR sensor board as needed.
