A robotic vacuum cleaner is provided to clean a space between a wall and a floor easily, and to clean the inside corners of the interior by installing at least one side brush at a bottom portion of its body. A robotic vacuum cleaner comprises a main body(10), a side brush(160), and a driving wheel(110). The main body has a suction port(130) for sucking air including dust particles or debris of bottom surface at its lower side. The side brush guides the dust or debris on a corner of inside to the suction port, and sucks the dust particles or debris on a periphery of a surface inclined at a predetermined angle from the bottom surface by turning toward the moving direction of the main body by rolling the driving wheel when the main body moves. The driving wheel is capable of shifting the body. The suction port is formed to the rear part of an extension line horizontally extended from the center of the side brush.
