If the Xiaomi Robot Vacuum doesn't work after scheduling a cleaning session on the Xiaomi Home App, please refer to the following steps:
1. Scheduled cleaning will not start when the battery level is below 30%. Please fully charge the battery before use.
2. Scheduled cleaning will not be possible if "Do Not Disturb" mode is enabled. Please disable "Do Not Disturb" mode and try again.
If the issue persists, please provide feedback to us in the Xiaomi Home App.
