A method for operating a self-propelling and self-steering floor-cleaning device is provided, wherein at least one map of at least one room to be cleaned is storable in a storage unit of the floor-cleaning device, as is a user-predeterminable cleaning plan having one or more cleaning tasks, wherein at least one cleaning task is associated with a particular room that is identifiable from a map, and the floor-cleaning device is placed in a room. In order to provide a method of this kind that enables efficient execution of the cleaning plan, when the cleaning plan is executed, the floor-cleaning device determines whether the room in which it is placed is the particular room, and, if the result of this determination is negative, performance of the cleaning task is not carried out, is interrupted, or is ended. A floor-cleaning device for performing the method is also provided.

Method for operating a floor-cleaning device and floor-cleaning device

A self-propelled, self-steering floor cleaner is provided, including a cleaning device with at least one cleaning unit for cleaning a floor surface of a room having at least a section of an obstacle therein that is not in contact with the floor surface, a transmission unit for emitting radiation directed at the obstacle and the floor surface, a detection unit for detecting reflected radiation and providing a detection signal, a control unit coupled to the detection unit, and a chassis for movement on the floor surface including a drive unit coupled to the control unit, it being determinable from the detection signal whether a space and a cleanable floor surface section are present underneath the obstacle, the drive unit being actuatable to move the floor cleaner for cleaning the floor surface section, with at least one cleaning unit. The invention also relates to a method for cleaning a floor surface.

The invention relates to a cleaning apparatus, comprising an operating unit for operating the cleaning apparatus, at least one functional unit for carrying out an operating instruction, and a control unit for receiving operating instructions performed on the operating unit and controlling the at least one functional unit based on said operating instructions, wherein an access authorization stored on an authorization carrier is required in order to operate the cleaning apparatus. In order to provide such a cleaning apparatus with a more user-friendly access control, it is proposed that the cleaning apparatus have a detection unit operatively connected to the control unit and configured for contactless detection of the access authorization and transmission thereof to the control unit, and that the access authorization be verifiable for its validity by the control unit. The invention further relates to a method for controlling access to a cleaning apparatus.

The invention relates to a cleaning tool for a cleaning device, the cleaning tool being subject to wear during operation. In order to make it easier to identify wear, the invention proposes that the cleaning tool comprise a sensor device with a sensor element which has a physical characteristic variable which changes as a function of the degree of wear of the cleaning tool. The invention also proposes a cleaning device having such a cleaning tool, the cleaning device having a detector device which is coupled to the sensor device for the purpose of sensing the change in the physical characteristic variable of the sensor element, and having an indicator device which is connected to the detector device.
