Abstract: A mobile robot and a controlling method thereof of the present disclosure includes: a main body which travels in an area; a tool mounted at the main body to assist n cleaning; a holder onto which the tool is held; and a charging stand which supplies operating power to move the main body, wherein when the tool becomes separated from the holder, upon receiving a tool separation signal from the charging stand, the main body moves to a position of the tool so that the tool may be mounted at the main body. Accordingly, when the tool becomes separated, the mobile robot may detect a position of a user based on a map, and may move upon recognizing a user having the tool, without requiring the user to move, thereby enabling the user to mount the tool and designate an operation in a convenient manner.
