A downshift assembly has a first transmission element, a second transmission element and a third transmission element. A main shaft is arranged coaxially to the upshift assembly and a layshaft is arranged parallel to the main shaft. A first idler gear is arranged coaxially to the main shaft and axially between the upshift assembly and the downshift assembly and is connectable to the main shaft for conjoint rotation by a first shift unit. The first idler gear is connectable to the third transmission element of the downshift assembly for conjoint rotation by a second shift unit.

Abstract: A floor vacuum cleaner for cleaning a floor surface has a chassis with a chassis frame for traveling over the floor surface. A suction nozzle aspirates an airflow in the region of the floor surface. The suction nozzle is mounted relative to the chassis in the direction of travel to the front left and front right in each case by way of a mounting arrangement formed of a journal and a guide. The mounting arrangement allows a tilting of the suction nozzle about the journals, a rotation of the suction nozzle about a longitudinal axis, and a vertical movement of the suction nozzle, but a movement of the suction nozzle in the longitudinal direction of the chassis is prevented.

Abstract: A method creates an environment map of a surrounding region for the operation of a mobile, self-moving appliance, in particular a floor cleaning appliance such as a vacuum cleaning and/or sweeping and/or mopping robot. The method includes: detecting the region around the appliance with at least one first sensor, to create a first horizontal plane of the environment map; detecting the region around the appliance with at least one second sensor, to create a second horizontal plane of the environment map, which is different from the first horizontal plane; and planning a movement path of the appliance based on the first and second planes of the environment map, in order in particular to achieve the maximum floor processing possible in the surrounding region.

Abstract: An operating method operates a mobile, self-moving appliance. The method is performed in a wall following mode and includes: moving the mobile, self-moving appliance along a first wall; detecting a second wall, which forms a corner with the first wall; and moving away from the second wall, until there is a first predetermined distance between a front point of a housing corner of the appliance and the second wall. The appliance is rotated about a center point so that the front point of the housing corner faces the second wall and is at a second predetermined distance therefrom. Forward movement of the mobile, self-moving appliance proceeds so that the appliance is aligned parallel to the second wall. The second predetermined distance between the front point of the housing corner and second wall remains substantially constant during the forward movement. A mobile, self-moving appliance is configured to perform the method.

Abstract: A method for autonomous processing of floor surfaces by a mobile, self-driving device, in particular a floor cleaning device such as a vacuum and/or sweeping and/or mopping robot. The method includes: the mobile, self-driving device carrying out an exploration travel in a proposed floor processing region, detecting obstacles and/or objects located on the floor by a detection device, classifying the obstacles and/or objects as movable or not movable, and transporting the obstacles and/or objects classified as movable to at least one collection point. The collection point is cleaned before obstacles and/or objects classified as movable are transported to the collection point.

Abstract: A method for operating a mobile, self-driving appliance, in particular a floor cleaning appliance, such as a vacuuming robot and/or sweeping robot and/or mopping robot, uses a detection facility provided for navigation to determine whether a cover element, which is disposed on an appliance housing of the mobile, self-driving appliance, is open or closed. When the cover element is open, the mobile, self-driving appliance performs a driving maneuver for independently closing the cover element.

Abstract: A robot contains a battery module which has a battery and a battery manager managing the battery. The battery manager is configured to set the battery module into a deep sleep mode upon receiving a sleep signal and to terminate the deep sleep mode upon receiving a wake-up signal. The robot is configured to generate the wake-up signal without the use of energy from the battery. A robot arrangement contains the robot and a charging station for the robot which has a counter-interface for providing the electrical energy. The robot can be coupled to the charging station such that the interface can be supplied with the electrical energy from the counter-interface. In a method for operating a robot or the robot arrangement, the wake-up signal is generated without the use of energy from the battery.

Abstract: A method for controlling a robot for the wet cleaning of a floor surface includes traveling over the floor surface and wet cleaning a portion of the floor surface which has been traveled over. A degree of wetness of a portion of the floor surface to be traveled over by the robot is determined, and the portion is traveled over only when the degree of wetness is below a predetermined threshold value. A robot for wet cleaning of a floor surface is also provided.

Abstract: A floor treatment facility includes a chassis, a running gear for guiding the chassis over a floor, a treatment facility for treating the floor, a suction mouth, and a guide for applying the treatment facility movably along a predetermined path in relation to the chassis. The path extends in a vertical direction in relation to the floor and the path encloses a predefined angle with a plane parallel to the floor when the floor-treatment facility is standing on an even floor. The angle is at most approximately 45°.

Abstract: A method for determining a distance between a cleaning robot and an obstacle. The cleaning robot has a first distance measuring system for a far measuring range and a second distance measuring system for a near measuring range. The second distance measuring system includes a camera. a) if the obstacle is located in the far measuring range, the distance between the cleaning robot and the obstacle is determined by way of the first distance measuring system. b) if the obstacle is located in an overlap region of the far measuring range and the near measuring range, the distance between the cleaning robot and the obstacle is determined by way of the first and the second distance measuring systems; c) if the obstacle is located in the near measuring range, the distance between the cleaning robot and the obstacle is determined by way of the second distance measuring system.

Abstract: A cleaning robot is configured to clean a predetermined floor area. A method for controlling the cleaning robot includes determining a section of the floor area, the treatment of which by the cleaning robot is intended to differ from that of the remaining floor area, deactivating a cleaning facility of the cleaning robot, controlling the cleaning robot to travel along a boundary of the section, detecting a user-controlled confirmation of the boundary traveled along, and enabling the cleaning facility. A control apparatus and a system including a cleaning robot are also provided.

Abstract: A floor cleaning system includes a mobile, self-driving apparatus and a portable additional apparatus for a user. The self-driving apparatus, in particular, is a cleaning apparatus for autonomous treatment of floor areas, such as a vacuuming robot and/or sweeping robot and/or wiping robot. The user apparatus has an operating unit, a communication unit, and a position detection unit. Using the position detection unit, the user defines the floor area to be cleaned in that the user walks, with the additional apparatus, along a cleaning path or delimiting path that can be transmitted to the mobile, self-driving apparatus in order for the mobile, self-driving apparatus to clean along the cleaning path or to clean the floor area included within the delimiting path in accordance with a cleaning request. There is also described a method for the automatic treatment of floor areas with the aid of the floor cleaning system.

Abstract: A method for identifying an error state in a cleaning robot which has a collection container for collecting dirt. According to the method an average duration for filling the collection container with dirt during the operation of the cleaning robot is determined. The existence of an error state is identified as soon as a single duration for filling deviates from the determined average duration for filling by more than a predefined difference value.
