Abstract: An air purifying system includes a robot cleaner configured to generate map information during vacuum cleaning and at least one air purifier that is operated based on the generated map information. Air purifying is performed using updated map information acquired by the robot cleaner during cleaning. The at least one air purifier includes two portable air purifiers mounted on a base air purifier. The two portable air purifiers are configured to be lifted from the base air purifier and moved to separate indoor rooms. The base air purifier includes a controller that determines, based on the generated map information and other information, which rooms the two portable air purifiers should be placed in so that air purifying may be efficient.
