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 influencing the device-typical sound emission of a cleaning device, wherein the cleaning device has a device housing and a cleaning mechanism for carrying out a cleaning activity on a surface to be cleaned, wherein the cleaning device emits device-typical sound while carrying out the cleaning activity, and wherein the device-typical sound is detected and analyzed with respect to at least one sound frequency contained therein. In order to adapt the soundscape of the cleaning device in such a way that a user can ascertain a proper functionality of the cleaning device, a displaceable section assigned to a flow channel of the cleaning device is displaced relative to the flow channel and/or the device housing in dependence on the analysis result until a characteristic sound frequency for the cleaning activity emitted by the cleaning mechanism has a defined amplitude.

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.

An AI robot for cleaning in consideration of a user's action includes a camera to acquire a first image data for the user, a cleaning unit including a suction unit and a mopping unit, a driving unit configured to drive the AI robot, and a processor to determine the user's action using the first image data, determine a cleaning schedule in consideration of the user's action, and control the cleaning unit and the driving unit based on the determined cleaning schedule.

A system providing a barrier for an autonomous floor cleaner includes an artificial barrier generator that radiates one or more infrared signals.
