Dirty charging contacts are the primary cause. The failure to maintain cleanliness results in loss of charging ability.
- Wipe the three circular charging contacts on the bottom of the robot with a clean, dry cloth.
- Wipe the two charging contacts on the Home Base with a clean, dry cloth.
- You can use a melamine foam pad to remove built-up debris.
If that didn't work, verify the power supply.
- Ensure you are using only the provided power supply cord plugged into a standard household AC outlet. Do not use any other cord or a power converter.
- Check that the Home Base cord is not damaged. If it is, it must be replaced by contacting Customer Care.
Prevention: Keep the robot and Home Base in a dry location. Do not handle them with wet hands.
