ABSTRACT:
A complex type cleaner includes: a cleaner body having at least one of a dust collecting container for storing dust or foreign materials and a water collecting container for storing contaminated water; and a suction head having a dust suction opening disposed at a lower portion of the cleaner body and sucking dust when the cleaner performs a vacuum cleaning and a suction head having a suction nozzle for sucking contaminated water when the cleaner performs a water cleaning. By implementing both vacuum cleaning function for sucking dust and water cleaning function in one cleaner, a cost can be reduced, users' convenience can be improved, and the cleaner can be conveniently kept in storage.
