PROBLEM TO BE SOLVED: To provide a bathtub cleaning device capable of automatically cleaning up the inner wall of a bathtub even when no remaining hot water or water is left in the bathtub. SOLUTION: The bathtub cleaning device is designed to clean its bathtub after setting a device body 1 to be freely movable on a bottom Tb of the bathtub T so that it can move around the inner wall Ts of the bathtub T. The device body 1 is composed of a rotary brush 2 which is pressed and rotated against the inner wall Ts of the bathtub T to clean the surface, a drive roller 3 which rotates and moves together with the rotary brush 2 along the inner wall Ts of the bathtub T, a lowering means 4 which puts down the rotary brush 2 in the lower direction, and a pressing roller 5 which presses the device body 1 onto the inner wall Ts of the bathtub T. The pressing roller 5 is designed to press the device body 1 to the inner wall Ts of the bathtub T by using a propulsive force caused by frictional rotation of the bottom Tb of the bathtub T.
