1. A mobile robot comprising:
a main body;
a driving unit installed on the main body and configured to supply power for a travel of the mobile robot;
a first rotary member, a second rotary member and a third rotary member, capable of accommodating respective cleaners and providing moving power sources for the travel of the mobile robot by performing respective rotational motions about a first rotation axis, a second rotation axis and a third rotation axis by power of the driving unit; and
a controller configured to control the driving unit for the first rotary member having a first rotational speed and the second rotary member having a second rotational speed to rotate at same speed in opposite directions and for the third rotary member having a third rotational speed to rotate in same direction as one of a first rotation direction of the first rotary member or a second rotation direction of the second rotary member, wherein the third rotational speed is at least 10% of the first rotational speed or the second rotational speed,
wherein the first rotation axis corresponding to the first rotary member and the second rotation axis corresponding to the second rotary member are each inclined to have a predetermined angle with respect to a central axis, corresponding to a vertical axis of the mobile robot, for and the first rotary member and the second rotary member to each have are each disposed to be at an angle with respect to a ground surface,
wherein the central axis is a Z-axis which is perpendicular to the ground surface to be cleaned which is a X-Y plane defined by X and Y axes, and
wherein the third rotation axis corresponding to the third rotary member is parallel to the central axis for the third rotary member to be parallel to the ground surface.
