A moving robot system includes a moving robot which travels in a cleaning area, generates a map of the cleaning area, moves based on the map, and sucks foreign substances; and a terminal which inputs a cleaning command to the moving robot, based on the map, wherein the moving robot determines that the moving robot is in an isolation state, when the moving robot is unable to move due to a surrounding obstacle while traveling in the cleaning area, and sets a virtual wall in an isolation position where isolation is occurred and avoids the isolation position during a next cleaning operation.
