To remove suspended matter and the stains sticking to the inside surface of a bathtub by mounting a net for scooping suspended hair, etc., at the inside surface of a frame fixed to a handle and mounting a mop at the outer side of this frame.

The frame 2 of an arbitrary shape is fixed to the front end of the handle 1. The fine-meshed net 3 is mounted over the entire surface on the inner side of the frame so that the hair, yarn dust, fur, etc., suspended in the water may be scooped. The mop 4 consisting of soft base stock is mounted at the outer side of the frame 2 to allow the removal of the stains deposited on the flanks and floor surface of the bathtub. The fine-meshed woven net or nonwoven fabric consisting of the soft base stock is used for the net 3. The inside surface of the bathtub is rubbed by the mop 4, by which the stains are removed. The dust suspended in the water is scooped and removed by the net 3. The stains on the inside surface of the bathtub may thus be removed.
