A method for operating a cleaning appliance, which moves automatically inside a surrounding area, wherein the cleaning appliance performs a cleaning of a defined spatially defined partial surface area of the surrounding area. To optimize the cleaning operation as a function of a measured soiling, it is proposed that a detection device of the cleaning appliance measures a level of soiling of the partial surface area during the cleaning of the partial surface area, wherein the level of soiling is compared to a defined reference level of soiling and wherein the partial surface area is enlarged automatically by adding a defined additional partial area, which adjoins the partial surface area, if a level of soiling above the reference level of soiling is determined inside the partial surface area.

A wet cleaning device, in particular a wet wiping device, has a cleaning roller which is rotatable about a roller axis and has a cleaning lining. In order to create a wet cleaning device in which the regeneration effect is optimized, in particular while using a minimum of liquid, the wet cleaning device has a decelerating element to assist the removal of liquid and/or of dirt from the cleaning roller, which element has an impact edge directed radially outwards with respect to the roller axis and is arranged between fibers of the cleaning lining during a regeneration operation in such a way that the free ends of the mechanically unloaded fibers project outwards in the radial direction beyond the impact edge.

A method for the operation of a cleaning appliance automatically moving within an environment, wherein the cleaning appliance cleans a surface in accordance with a predetermined work schedule, wherein at least one level of contamination of the surface is determined, and a cleaning task is controlled as a function of the level of contamination. In order to make the cleaning operation more flexible and individual, the level of contamination is entered on a map associated with positional information of the environment, wherein a user undertakes editing of the map, that is to say, defines on the map surface zones of the surface and manually assigns a cleaning task of the cleaning appliance to at least one surface zone.

Method for the operation of an automatically moving cleaning appliance

A method for operating a cleaning device that automatically moves within an environment, wherein the cleaning device cleans a surface according to a prescribed work plan, wherein a detection device of the cleaning device detects contamination levels of several partial surface areas of the surface, wherein a cleaning operation of the cleaning device is varied as a function of the detection result, wherein an overall contamination level is determined for the surface from the contamination levels of several partial surface areas, and the cleaning operation is performed with cleaning parameters identical to the overall contamination level for the entire surface. In order to create an alternative to conventional operating methods, the determined overall contamination level is compared with at least one reference contamination level, specifically with an overall contamination level determined during a chronologically preceding cleaning activity.

A method for operating a self-propelled cleaning device, in particular a vacuuming and/or wiping robot, the cleaning device traveling in one or more rooms on the basis of a stored room map and, if necessary, carrying out cleaning jobs. The cleaning device furthermore receives information from a fire sensor, in particular initiates an emergency call in the event of a fire alarm. In order to devise a method which offers active help to individuals present in the rooms, the cleaning device, in the event of a fire alarm, outputs an acoustic and/or optical signal and moves toward an emergency exit or toward a safe location starting from its current location.

The invention relates to a self-propelled floor treatment device (), in particular to a cleaning robot, with a floor treatment element (), at least two motorized wheels () and a detection device for detecting a floor type of a surface to be treated. In order to easily achieve an optimal detection of the floor type, it is proposed that the detection device have a frictional resistance element (), which contacts the surface during a movement in such a way that a resultant force outside of a reference axis () acts on the floor treatment device (), wherein the reference axis () is oriented parallel to a main direction of movement () of the floor treatment device () prescribed by the orientation of the wheels (), and is aligned centrally between the wheels () in relation to a direction perpendicular to the reference axis (). Further proposed is a method for operating a self-propelled floor treatment device ().
