Abstract

A system has at least two self-traveling floor treatment apparatuses, wherein each of the floor treatment apparatuses features a navigation and self-localization device that is designed for generating an environment map based on environment data of the environment of the floor treatment apparatus, which is recorded by means of a detection device. In order to realize an advantageous cooperation between the floor treatment apparatuses, it is proposed that a common memory unit for storing environment maps and a computing unit are assigned to the floor treatment apparatuses, wherein the computing unit is designed for comparing an environment map of a first floor treatment apparatus with an environment map of a second floor treatment apparatus and/or with an environment map stored in the common memory unit and for specifying which of the environment maps is stored in the common memory unit and/or in a local memory of a floor treatment apparatus based on a defined selection criterion.
