and a wireless communication module provided in the case to transmit the cleaning history information to the external terminal, when the external terminal asks the cleaning history information. ## Claims ### Claim 1 A robot cleaner comprising: a case; a suction device provided in the case; a suction nozzle configured to suck dust from a floor by driving of the suction device; a dust collection device for collecting foreign substances contained in the air sucked via the suction nozzle; a drive module including wheels to allow movement; a controller configured to control the driving of the suction device and the drive module, and configured to generate cleaning history information, the cleaning history information including map information on a cleaning area and moving path information; a memory configured to store the cleaning history information; and a wireless communication module provided in the case and configured to transmit the cleaning history information to an external terminal when the robot cleaner receives a signal requesting cleaning history information transmitted from an external terminal, wherein the cleaning history information includes bibliographical information for distinguishing a series of cleanings from start to end of the cleanings from other cleanings, wherein the robot cleaner creates the bibliographical information as an individual list, wherein a preset number of individual lists are stored in a chronological order, and a new individual list replaces an oldest individual list for storage when the preset number has been reached. ### Claim 2 (depends on 1) The robot cleaner of claim 1, wherein the bibliographical information includes at least one of a cleaning date, a cleaning start time, a cleaning end time and a cleaning mode. ### Claim 3 (depends on 1) The robot cleaner of claim 1, wherein the robot cleaner starts to record the cleaning history information when the cleaning starts, and the robot cleaner stores the individual list based on the recorded cleaning information when the cleaning ends normally. ### Claim 4 (depends on 3) The robot cleaner of claim 3, wherein the normal ending of the cleaning comprises at least one of restituting of the robot cleaner to a recharging base after the cleaning, restituting of the robot cleaner after charging a battery and external inputting of the cleaning ending. ### Claim 5 (depends on 1) The robot cleaner of claim 1, wherein the individual list is not stored by the robot cleaner when the cleaning ends abnormally. ### Claim 6 (depends on 1) The robot cleaner of claim 1, wherein the robot cleaner stores a map file corresponding to a map information on a cleaning area for each of the individual lists and a moving path file corresponding to the moving path information. ### Claim 7 (depends on 6) The robot cleaner of claim 6, wherein the robot cleaner transmits the individual list and the moving path file separately. ### Claim 8 (depends on 1) The robot cleaner of claim 1, wherein the wireless communication module comprises a Wi-Fi module provided with an Access Point (AP) by the robot cleaner. ### Claim 9 (depends on 8) The robot cleaner of claim 8, further comprising: an NFC module provided in the case to provide an AP (Access Point) information to an external terminal via NFC communication for access to the AP. ### Claim 10 A robot cleaner system comprising: a robot cleaner configured to provide cleaning history information including map information of a cleaning area and moving path information; and a mobile terminal configured to wirelessly communicate with the robot cleaner, to request the robot cleaner for the cleaning history information, to display a map based on the received cleaning history information and to display a sequential moving path of the robot cleaner on the displayed map, wherein the robot cleaner transmits the cleaning history information to the mobile terminal when the robot cleaner receives, from the mobile terminal, a signal requesting cleaning history information, wherein the cleaning history information includes bibliographical information for distinguishing a series of cleanings from start to end of the cleanings from other cleanings, and wherein the robot cleaner creates the bibliographical information as an individual list, wherein a preset number of individual lists are stored in a chronological order, and a new individual list replaces an oldest individual list for storage when the preset number has been reached.
