Strange Warning+Sound

Hi, my wife and i awakend in the middle of the night several times of our Robot played a sound and said something about Alarm 3 times this night.
Checked the app and no notifications, Fw upgrades or anything.
Have no scheduled cleaning either.
What is it and how do i STOP it?

Hello,

It would be very helpful if you could provide a video demonstrating the robot's voice output.

Also, could you please provide us with the app's firmware version and the serial number (SN) from the label on the bottom of the robot?
