Abstract: A dust removal paper for use with a mop is composed of a rectangular main body and two sleeve-joint portions. The sleeve-joint portions are connected with two short sides of the main body separately and each include a sleeve-joint channel. The dust removal paper can be connected with the mop via the sleeve-joint channels for mopping and cleaning the ground or wall. Because the mop does not need tiny hooks for connection with the dust removal paper, the dust removal paper can abut much against the ground or wall to enhance the cleaning efficiency. Besides, when two swing links of the mop pivot 180 degrees to exchange their positions, the dust removal paper can be flipped upside down automatically. It is very convenient in operation.
