METHOD FOR OPERATING AN INDEPENDENTLY MOVING SURFACE TREATMENT DEVICE

A method for operating an independently moving surface treatment device, wherein the surface treatment device can be displaced in the surroundings and, in the process, performs surface treatment tasks and wherein an obstacle detection device of the surface treatment device measures an obstacle within the surroundings. The surface treatment device remains motionless at a predefined location, in particular within a movement range of a certain object, in the surroundings during a time interval that was predefined by the user. The obstacle detection device repeatedly measures a distance to a certain object during the time interval and evaluates the measured values of the distance in respect of a temporal change, and/or wherein the obstacle detection device detects a possibly occurring collision with the object during the time interval, wherein an alarm signal is output in the case of a change beyond a predefined threshold and/or in the case of a collision.
