A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

A work system comprising a first autonomous work machine and a second autonomous work machine, wherein the first autonomous work machine includes: a detection unit configured to detect dirt on the second autonomous work machine; and a notification unit configured to, if the detection unit detects dirt, notify the second autonomous work machine of dirt information indicating the detection of the dirt, and the second autonomous work machine removes the dirt or waits in a predetermined position in response to the notification of the dirt information by the notification unit.

A bag-based filtering device for collecting debris from a cleaning robot via a debris evacuation station includes a filter bag configured to separate at least the portion of the evacuated debris from a flow of air generated by the evacuation station. The filtering device includes a conduit extending inward from an opening of the filter bag into the receptacle. The conduit is configured to pneumatically connect a receptacle of the filtering device with an inlet of the filtering device to direct the flow of air generated by the evacuation station through the filter bag to separate at least the portion of the evacuated debris from the flow of air.

Provided is a highly reliable technology for optimizing an action for controlling an environment in a target space. An action optimization device for optimizing an action for controlling an environment: acquires environmental data related to a state of the environment; performs time/space interpolation on the acquired environmental data; trains an environment reproduction model, based on the time/space-interpolated environmental data, such that, when a state of an environment and an action for controlling the environment are input, a correct answer value for an environmental state after the action is output; trains an exploration model such that an action to be taken next is output when an environmental state output from the environment reproduction model is input; predicts a second environmental state corresponding to a first environmental state and a first action by using the trained environment reproduction model; explores for a second action to be taken for the second environmental state; and outputs a result of the exploration.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.
