An autonomous mobile robot cleaner that can thoroughly clean areas along walls or other obstacles in a room. During a cleaning operation, the robot cleaner creates map information about already cleaned areas and areas where an obstacle is present and stores the map information in a memory. The robot cleaner performs a basic cleaning operation to clean areas while moving in the areas in accordance with a predetermined movement procedure. Subsequently, the robot cleaner performs an uncleaned area cleaning operation to clean uncleaned areas that cannot be cleaned by the basic cleaning operation, based on the map information. Thereafter, the robot cleaner performs an edge cleaning operation to clean the edge of an obstacle based on the map information.
