Why does the Xiaomi Robot Vacuum X20+ fail to connect to the Xiaomi Home App?

If the Xiaomi Robot Vacuum X20+ fails to connect the Xiaomi Home App, please refer to the following steps to troubleshoot:
1. Check whether the Wi-Fi is 2.4GHz. The robot vacuum only can connect Xiaomi Home App in 2.4GHz Wi-Fi instead of 5GHz Wi-Fi;
2. Check whether the router is working properly to ensure smooth network operation;
3. Check whether the Wi-Fi name or password has been changed. You can try reset Wi-Fi;
4. Try to connect to the mobile phone’s hotspot;
5. Check whether the router is connected to too many smart devices, causing the network to slow down or the router to be unresponsive. You can restart the router and try again;
6. Check whether the phone has restricted the permissions of the App, such as Internet access, positioning, etc. Please allow the permissions and try again;
7. The connection failure can also be related to the phone model. You can try to use other different models of mobile phones to try to connect.
If the problem is still not solved, please contact the local official after-sales service center for further assistance.
