Robotic Cleaner

The present invention relates to a robot vacuum cleaner. The robot vacuum cleaner is configured such that a virtual plane passing through a mop contact part with a small area passes through the center of gravity of the robot vacuum cleaner, so that the robot vacuum cleaner can be driven while a mop effectively wipes the floor. The robot vacuum cleaner comprises: a main body including a base and a cover covering the base, and including a battery, a water tank, and a motor inside; and one or more circular mop attachment plates installed on the bottom surface of the base, detachable and rotatable by the motor, and having at least one part which is in contact with the floor surface. 본 발명은, 로봇 청소기에 관한 것이다. 이러한 로봇 청소기는, 작은 면적을 가지는 걸레접촉부분을 지나는 가상평면이 로봇 청소기의 무게중심을 지나도록 구성됨으로써, 걸레가 바닥면을 효과적으로 닦으면서 주행할 수 있다.
