Why does the Xiaomi Robot Vacuum 6 fail to upgrade?

If the Xiaomi Robot Vacuum 6 fails to upgrade, please refer to the following troubleshooting steps:
1. Ensure the robot vacuum is docked at the omni station during the upgrade process.
2. Before updating, make sure the robot vacuum is placed on the omni station and has at least 30% battery. If the battery is too low, allow the robot vacuum to charge before attempting the upgrade again.
3. Check your home Wi-Fi network to ensure it is stable and connected. A weak or unstable network can interrupt the update process.
4. Do not operate or move the robot vacuum while it is updating. Any interruption during the upgrade can cause failure or delays.
5. Do not exit the upgrade interface in the Xiaomi Home App or let the screen turn off during the upgrade process.
6. If the update continues to fail, try restarting your router and the robot vacuum, then attempt the upgrade again.
7. For persistent issues, submit feedback through the Xiaomi Home App for further assistance.
