Abstract
A method for operating an automatically movable surface treatment device that can move in a room and possibly carries out surface treatment. An ultrasonic sensor detects ultrasound, in particular ultrasonic waves reflected at obstacles. The ultrasonic sensor detects glass breakage noises, wherein frequencies of sound detected by means of the ultrasonic sensor are compared with reference frequencies typically occurring in the event of a glass breakage, and wherein, in the event of a match, a glass breakage, in particular a break-in through a pane of glass of a window or of a door, is determined. A system comprising an automatically movable surface treatment device having an ultrasonic sensor and a house alarm system in which the surface treatment device is integrated in terms of communication.
