1. A cleaning robot, comprising:
- a main body to travel on a floor to be cleaned;
a dust collecting unit installed in the main body; and
a corner cleaning unit installed in the main body, and comprising a suction member having a suction arm unfolded from the main body by means of rotation, and a rotatable cylinder connected to the suction arm;
a movable member rotatably coupled around the rotatable cylinder of the suction member by a torsion spring such that the movable member moves upwards and downwards together with the suction member;
a driving unit to rotate the movable member;
supporting brackets provided in the main body to support the driving unit;
at least one elevation guide face formed at one of the supporting brackets to allow the movable member to move upwards and downwards along the elevation guide face as the movable member rotates; and

Abstract
A cleaning robot to prevent a suction member from moving upwards when the suction member is rotated during a collision with an obstacle, and which completely unfolds the suction member when a lower surface of the suction member travels on an uneven floor. The cleaning robot includes a main body to travel on a floor to be cleaned, a dust collecting unit, and a corner cleaning unit. The corner cleaning unit includes a suction member having a suction arm with a rotatable cylinder, a movable member rotatably coupled around the rotatable cylinder by a torsion spring such that the movable member can move upwards and downwards together with the suction member, a driving unit, supporting brackets, at least one elevation guide face to allow the movable member to move upwards and downwards along the elevation guide face as the movable member rotates, and at least one guide knob.

11. A cleaning robot, comprising:
-
a main body; and a corner cleaning unit having a suction member, and to move the suction member in a folding direction and an unfolding direction with respect to the main body, and to move the suction member in an upward direction and a downward direction with respect to the main body, when the suction member moves to the folding direction and the unfolding direction; and wherein the corner cleaning unit comprises; a driving unit mounted to the main body to control the suction member to move in one of the folding direction and the unfolding direction; and a bracket mounted to the main body to guide the suction member to move in one of the downward direction and the upward direction. - View Dependent Claims (12, 13, 14, 15, 16)
