A telescopically rotatable mop, comprising: an internal and external rod (10) (20) fitting to each other in a linearly and telescopically movable state; an engaging element (30) positioned within the opening at the top of the internal rod (10); a driving element (50) formed in an elongated shape and positioned within the external rod (20) in such a way that the driving element (50) is moved up and down synchronically with the external rod (20); an actuating element (40) positioned within the engaging element (30) for accommodating the driving element (50), the engaging element (30) being driven in a single direction when the actuating element is rotated by the driving element. An annular element (33) rotatable clockwise and counterclockwise at 360° is mounted on the top portion of the engaging element (30). The actuating element received within the engaging element (30) has a smaller length, thereby creating a gap for the lifting and lowering purposes. In this way, a more smooth operation with less effort is ensured when the internal and external rods rotate in a telescopic way.
