Abstract: An automatically moving floor treatment appliance has an appliance housing, a drive, a detector for detecting surrounding area features, and a computer that transmits control commands to the drive, based on the surrounding area features detected by the detector. The detector has a plurality of inner and outer fall sensors arranged on an underside of the appliance housing, which detect a distance of the floor treatment appliance from the surface. The computer controls the drive to change a movement of the floor treatment appliance when the distance detected by the fall sensor is greater than a threshold value defining a slope. The fall sensors are interconnected in an evaluation circuit of the detection means so that the detection signals of the totality of inner fall sensors can be evaluated independently of the detection signals of the totality of outer fall sensors.

Abstract: A method for operating a system with a first automatically moving floor processing device and a second automatically moving floor processing device in which the first floor processing device detects environmental features in an environment of the first floor processing device. The first floor processing device or a shared computing device allocated to both the processing devices generates a first area map based on the detected environmental features, and the first floor processing device also detects the second floor processing device, and the position of the second floor processing device is thereupon stored within the generated first area map. The second floor processing device receives information about a current position of the second floor processing device within the first area map, and controls a second floor processing activity as soon as the first floor processing device has detected the second floor processing device.

Abstract: An automatically moving floor treatment appliance has an appliance housing, a drive, a computing element and a plurality of fall sensors. The computing element compares a detection result of a fall sensor with a known reference result, and when the detection result does not correspond with the reference result, determines a malfunctioning of the fall sensor. The computing element determines distances detected chronologically successively by the same fall sensor during a movement of the appliance with one another, and when the distances are identical, determines a malfunctioning of the fall sensor, and/or compares a detection result of the leading fall sensor with a detection result of a trailing fall sensor and when the trailing fall sensor detects a slope without the leading fall sensor having detected the slope before, determines a malfunctioning of the leading fall sensor and the trailing fall sensor takes over the from the leading fall sensor.

Abstract: A method for operating a system with at least two floor processing devices includes detecting environmental features of an environment and generating an area map based on the detected features. The area map is divided into partial areas that are assigned to the floor processing devices so that each partial area is only processed by one of the floor processing devices. A movement route and a movement timespan of the floor processing device is detected and stored with the area map. Several partial areas are combined into partial area groups, and the partial areas are allocated to the floor processing devices based on the stored movement route and movement timespan so that a floor processing of a first partial area group by a first floor processing device takes place at essentially the same time as a floor processing of a second partial area group by a second floor processing device ends.

Abstract: A method for generating an area map for a floor processing device, wherein first and second floor processing devices detect feature data of an environment and process them into first and second area maps. The first floor processing device identifies an object based on a unique identifier of the object as an anchor point and stores relative positional information of the anchor point in a coordinate system of the first area map.

The first and second area maps are combined into a common global area map based on the relative positional information of the anchor point contained therein, and the unique identifier is a code that clearly identifies the object.

Abstract: A method for operating an automatically moving floor treatment appliance, wherein at least one floor treatment activity to be performed by the floor treatment appliance in a surrounding area is pre-planned for performance in a first time window having a defined start time and a defined time period. In the event that the first time window is not sufficient, at least a second time window is pre-planned, in which the floor treatment appliance continues the floor treatment activity. The floor treatment activity not completed upon the expiration of the first time window is stopped at the end of the defined time period of the first time window and is continued upon reaching a start time predefined for the second time window. The floor treatment plan specifies a cyclically successive floor treatment of several surrounding area subregions of the surrounding area according to a defined sequence of the surrounding area subregions.

Abstract: An automatically moving disinfection robot for disinfecting surfaces has a device housing, a drive means for the movement of the disinfection robot within a surrounding area comprising at least one room, a navigation means for the navigation and self-localization of the disinfection, a disinfection means, and a control means for controlling the disinfection activity. The control means controls a locally limited disinfection in only one subregion of the room, or a locally limited disinfection of only one object, in a fully automated manner. The disinfection means has a shielding means for separating the locally limited subregion to be disinfected from adjacent subregions of the same room. The shielding means is a housing, which is open only on one side and which is placed around the object or against the surface to be disinfected, so that the disinfection only takes place within the housing, but not outside of the housing.
