Possible Causes

Dirty or oxidized charging contacts, Faulty charging station, Damaged charging contacts on robot, Internal charging circuit failure

How to Fix / Troubleshooting

Safety first: Unplug the dock before cleaning contacts. Turn the robot OFF before inspecting the underside.

Steps:

  • 1. Clean contacts: Wipe the metal contacts on both the robot and dock with a dry cloth. If tarnished, use a cloth lightly moistened with isopropyl alcohol and dry thoroughly.
  • 2. Confirm dock power: Ensure the dock’s indicator light is on and the power cord is firmly connected.
  • 3. Reseat robot: Place the robot manually on the dock, ensuring proper alignment. Look for the charging indicator on the robot.
  • 4. Try another outlet: Plug the dock into a different wall outlet to rule out power issues.

When to call a technician: If the robot still does not charge despite clean contacts and a powered dock, the internal charging circuit or battery pack may be faulty and should be checked by a technician.
