Abstract: A ROTATABLE MOP HAS A ROD ASSEMBLY (10), A ROTATING ASSEMBLY (20), AN EXPANSION ASSEMBLY (30) AND A HEAD ASSEMBLY (40). THE EXPANSION ASSEMBLY (30) HAS A FASTENING SEAT (31) AND A WIDENING SLEEVE (32). WITH AN UPPER HALF PART OF AN OUTSIDE WALL OF THE WIDENING SLEEVE (32) SCREWED ONTO THE SCREWED SEGMENT (314), AN LOWER HALF PART OF THE OUTSIDE WALL OF THE WIDENING SLEEVE (32) ABUTS AGAINST THE WIDENING SEGMENT (313), AND A TOP OF THE WIDENING SLEEVE (32) ABUTS AGAINST AN ABUTTING STOP (3142) WHEN THE ROTATABLE MOP EXPANDS AND RETRACTS, AN AREA OF THE FASTENING SEAT (31) AND THE WIDENING SLEEVE (32) ABUTTING EACH OTHER IS INCREASED. THEREFORE, THE FASTENING SEAT (31) AND THE WIDENING SLEEVE (32) CAN REDUCE THE SHAKE WHEN THE ROTATABLE MOP EXPANDS AND RETRACTS, AND THE ROTATABLE MOP CAN EXPAND AND RETRACT STEADILY.
