A cleaning device. The device includes a hollow shank having a first guide member at a front end and a second guide member joined with and perpendicular to the first guide member. A head is releasably coupled to the front portion of the shank. The head includes a longitudinal bar having an engagement member on the surface at the rear end. The engagement member is guided along the first guide member to move to the end prior to being rotated a predetermined angle about the shank clockwise or counterclockwise so as to urge against either end of the second guide member for securing the shank to the head. A first cleaning member is on one side of the head, and a sleeve put on the joint of the bar of the head and the front portion of the shank. This cleaning device with replaceable head can reduce the manufacturing cost and storing space.
