The invention relates to a cleaning system comprising a cleaning apparatus with at least one cleaning tool, a sensor device for detecting the propagation of vibrations as a result of the operation of the cleaning apparatus and for providing input information relating thereto, and a data processing device on which an application program is ran or can be ran and by means of which the input information can be analyzed, wherein during the analysis of the input information, it can be ascertained whether the detected propagation of vibrations is an abnormal propagation of vibrations, indicating an actual operating state which deviates from a normal operating state of the cleaning apparatus, and the cause of the abnormal propagation of vibrations can be ascertained on the basis of the deviation and/or a corrective measure with respect to correcting the cause of the abnormal propagation of vibrations can be provided by the data processing device. The invention additionally relates to a method for operating a cleaning system.
