Abstract
A method for operating a floor treatment apparatus that travels by itself within an environment, wherein a control and evaluation unit monitors the operating status of the floor treatment apparatus, detects an error condition of the floor treatment apparatus and initiates the output of an information signal in case an error condition occurs. In order to locate the floor treatment apparatus in a particularly simple and convenient fashion during an error condition, it is proposed that an optical signal output device of the floor treatment apparatus emits an optical information signal, which generates a light projection that represents a directional indicator, wherein the directional indicator points from a projection site within the environment in the direction of the current position of the floor treatment apparatus.
