Abstract: A rotatable mop includes upper and lower rods, as well as a fixing seat sheathed between the upper and lower rods. The fixing seat contains a bolt and a sliding element screwed with the bolt. The sliding element is connected with a grip sheathed at an outer rim of the fixing seat, a bottom of the bolt is a shaft connected with a disc body having mop wool, brush wool or a brush cloth. When using the mop, by sliding up and down the grip along the fixing seat, the sliding element is driven to rotate the bolt clockwise or counterclockwise, such that the disc body rotates along a same direction, thereby constituting brushing to facilitate a cleaning operation. Additionally, a centrifugal force generated by rotation after using the mop spins dry water on the mop wool, brush wool or brush cloth, thereby dehydrating the mop more conveniently.
