PURPOSE: A blade module for cleaning is provided to prevent to remain a stain on a cleaned surface by minimizing residue of washing water used for a cleaning on the cleaned surface. CONSTITUTION: A blade module for cleaning comprises a blade tool(30), a balance weight(40), and a power transmitting member(50). The blade tool comprises a blade body(31), a joining protrusion(32), a collection space unit(33), a blade(35), a joining hole, and a sealing rail(34a). The joining protrusion unit is recessed toward the inner side of the blade body's bottom surface which is a opposite side of the joining protrusion unit. The blade cleans the surface to be cleaned according to rotating blade tools around the collection space unit, thereby gathering contamination and washing water to the central part. The sealing unit is formed in the inner circumference of the joining hole to keep an airtight and minimization of the friction resistance when the blade body rotates.
