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.

An operating method of a station device for discharging dust from a cordless vacuum cleaner includes detecting occurrence of an event requesting discharging dust from a dustbin included in the cordless vacuum cleaner to the station device, and performing a dust discharge operation for discharging dust in the dustbin to a collector of the station device based on detecting of the occurrence of the event. The performing a dust discharge operation includes transmitting, to the cordless vacuum cleaner via short-range wireless communication, a control signal for operating a first suction motor of the cordless vacuum cleaner, and operating a second suction motor of the station device in cooperation with the first suction motor.

A detection system including an autonomous collection device that is capable of moving on a floor surface and for collecting an object on the floor surface, and a station device for detecting an analyte from the object collected from the floor surface by the autonomous collection device. The autonomous collection device includes a moving part for moving on the floor surface, a primary electric blower for sucking the object on the floor surface, and a dust container for storing the sucked object. The station device includes a transfer pipe fluidically connected to the dust container of the autonomous collection device when the autonomous collection device is positioned in a home position, and a virus detection part for detecting the analyte from the object transferred from the dust container through the transfer pipe.
