If the Xiaomi Robot Vacuum 6 Max can't connect to the Xiaomi Home App, please refer to the following troubleshooting steps:
1. Check whether the robot vacuum is powered off. If it is, press and hold the power button to turn it on.
2. Check if the Wi-Fi signal is weak. Make sure the robot vacuum and omni station are in an area with a strong Wi-Fi signal. You can reset the network for the robot vacuum, then select a router network that is close to the robot vacuum for pairing.
3. Verify Wi-Fi network compatibility. Make sure you are using a 2.4 GHz Wi-Fi network. Ensure the Wi-Fi name does not contain special characters and is not too long.
4. Check if the phone system and Xiaomi Home App are updated to the latest version.
5. Check whether your home Wi-Fi is working properly. If there is something wrong with the Wi-Fi connection, reset the Wi-Fi of the robot vacuum, and then try reconnecting.
6. Check phone settings. Enable Bluetooth and Location permissions on your phone. Allow the App to have all required permissions. Keep the phone close to the robot vacuum during pairing.
7. If it persists, please contact the after-sales service for further assistance.
