6. Troubleshooting
If you encounter issues with your Conga 3890 Titanium, refer to the following common problems and solutions:
- Robot does not turn on: Ensure the robot is fully charged. Check if the power button is pressed correctly.
- Robot does not charge: Verify the charging base is plugged in and the power indicator is on. Clean the charging contacts on both the robot and the base.
- Wi-Fi connection issues: Ensure you are using the correct app for the Conga 3890. Check your Wi-Fi password for special characters or length restrictions. Try restarting your router and the robot.
- Robot loses map or creates new maps: This can sometimes occur due to Wi-Fi instability or if the robot is manually moved during a cleaning cycle. Ensure the charging base is in a stable location and the robot starts cleaning from it. You may need to delete incorrect maps in the app and allow the robot to remap.
- Poor cleaning performance: Check and clean the main brush, side brushes, and filters. Empty the dust tank. Ensure no obstacles are impeding the robot's movement.
- Robot gets stuck frequently: Clear obstacles from the cleaning path. Ensure cables and small items are picked up from the floor.
- Error messages/lights: Refer to the app for specific error codes or consult the full manual for detailed explanations of indicator lights. Often, cleaning sensors or clearing blockages resolves these.
