The controller also sets a cleaning region and a non-cleaning region based on cleaning data, which is calculated based on the dust information and the number of times of cleaning. This helps prevent cleaning from being repeated unnecessarily and allows for cleaning depending on the number of times of cleaning, despite a small amount of dust. Accordingly, an entire indoor area may be maintained in a constant clean state and cleaning efficiency may be enhanced.
