Abstract: A method for operating a self-propelled floor cleaning device, in a first operating step, drives the floor cleaning device across a first treatment path across the floor to be cleaned according to a predetermined driving strategy, or according to a predetermined algorithm, which is calculated on the basis of data, which are detected by sensors and thereby carries out a first cleaning step by a first cleaning device. In the first operating step, areas of the floor surfaces to be cleaned, which are cleaned in at least a second operating step by a second cleaning device, or which are excluded from the cleaning by the second cleaning device, are determined. A floor cleaning device, which is suitable for carrying out the method, has a chassis, a first cleaning device for dry cleaning a floor surface, and a second cleaning device for wet cleaning areas of the floor surface.

Abstract: The invention relates to a method (100) of operating a kitchen machine (1) suitable for preparing foods, including the following steps: specifying (104) a recipe (11) for preparing the foods, determining (106) a thematic category (20) assigned to the recipe (11). Furthermore, the invention relates to a kitchen machine (1) for preparing foods, as well as an ambience system (40).

Abstract: A food processor driven by en electric motor includes a stirrer vessel and a stirring mechanism in the stirrer vessel, an optional heater, and also a volatile or non-volatile memory in which useful date for using the food processor can be stored. The food processor is provided with a loudspeaker and a data file is used for producing sound by the loudspeaker, for example for outputting speech, music or sounds.

Abstract: A cleaning device includes an air flow generator for generating an air flow, which encompasses a first suction flow through a first suction line, which is arranged in flow direction of the air flow upstream of the air flow generator and which leads into a first collecting container, and a pressure flow in a pressure line, which is arranged in flow direction of the air flow downstream from the air flow generator. Using a Venturi nozzle, the air flow generates a second suction flow, which is separated from the first suction flow, through a second suction line, which leads into a second collecting container.

Abstract: A self-propelled floor cleaning device includes a manually controlled or program-controlled first cleaning vehicle, which moves across a treatment path across a surface, which is to be cleaned, including a first cleaning device for carrying out a dry cleaning step. A second cleaning vehicle, including a second cleaning device for carrying out a wet cleaning step, is coupled to the first cleaning vehicle such that the second cleaning vehicle follows the first cleaning vehicle on the treatment path thereof. The second cleaning vehicle can be connected to the first cleaning vehicle via a releasable mechanical coupling. However, it can also be in operative connection with the first cleaning vehicle via only a data transmission path.
