Abstract: The present disclosure provides a cleaning robot that communicates with peripheral devices over a 5G communication network and that preferentially cleans a region that needs to be cleaned the most based on the communication. Based on information about the use of a user terminal used in a movement space in which the cleaning robot moves or a collecting terminal collecting information about the behavior or locations of a user moving in the movement space, the cleaning robot preferentially moves to a region in which the user terminal or the collecting terminal is rarely used. That is, a region in which a user rarely travels, i.e. a region in which a large amount of dust or foreign substances is liable to accumulate, is cleaned preferentially by the cleaning robot, whereby the cleaning efficiency of the cleaning robot is improved.
