What is the Do Not Disturb feature of the Xiaomi Robot Vacuum S20?

During the Do Not Disturb (DND) period, the main unit will not respond to continued cleaning, scheduled cleaning, or active voice broadcast. DND mode is enabled by default at the factory, and the default period is from 11:00 PM to 9:00 AM.
To set the DND mode in the Mi Home/Xiaomi Home APP, please refer to the following steps:
Go to the Mi Home/Xiaomi Home APP >> select [Device card] >> tap the three-dot icon at the upper corner >> select [DND mode] >> turn on/off [DND mode].
Note:
During the DND period, the indicator goes off after 1 minute of charging.
