An autonomous cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes operating a drive system to move the cleaning robot in a forward drive direction along a first obstacle surface with a side surface of the cleaning robot facing the first obstacle surface, then operating the drive system to turn the cleaning robot such that the side surface of the cleaning robot faces a second obstacle surface, then operating the drive system to move the cleaning robot in a rearward drive direction along the second obstacle surface, and then operating the drive system to move the cleaning robot in the forward drive direction along the second obstacle surface.

A method for operating a cleaning system that comprises at least one self-traveling cleaning device that travels in an environment based on an environment map and carries out cleaning activities. The cleaning device accesses a database, in which multiple cleaning activities are stored. A user accesses the database and defines in advance at least one randomly occurring event, depending on the occurrence of which at least one certain cleaning activity is carried out. The user defines an event-dependent activity scenario and the activity scenario is carried out upon the subsequent occurrence of the defined event. At least one cleaning activity is also scheduled time-dependently, and predefined rules determine whether only the event-dependent activity scenario or only the time-dependently scheduled cleaning activity is carried out if the time of an occurrence of a defined event falls short of a predefined minimum time interval.

A method of controlling movement of a robotic cleaning device and a robotic cleaning device performing the method. The method comprises acquiring historical data forming a representation of an environment in which the robotic cleaning device moves, and controlling movement of the robotic cleaning device to exert a force onto an object located in the environment to move the object based on the acquired historical data.

A method for adjusting at least one parameter range of a device parameter of a floor treatment device for treating a surface. The parameter range is available on the floor treatment device and depends on a floor type of the surface to be treated. The parameter range comprises a defined scope of values of the device parameter selected by the user for the treatment of the surface. The user moves the floor treatment device over the surface to be treated during an adjustment process, wherein a limiting device parameter, which is dependent on the nature of the surface and upon its use for the treatment of the surface leads to a predefined fault, is automatically determined during the movement of the floor treatment device, and wherein the parameter range is automatically adjusted based on the determined limiting device parameter which defines a range end of the parameter range.
