Abstract: The present disclosure relates to a cleaner capable of easily separating a filter module from a main body of the cleaner and separating and assembling the separated filter module again. Disclosed is a cleaner including: a main body; a suction motor disposed in the main body and configured to generate a suction force so as to suction air; a dust separator separating dust from air by generating a cyclone flow in air introduced by the suction motor; and a filter module having a filter for filtering air discharged from the suction motor and being detachable from the main body. Here, the filter module is configured to be easily separated from the main body of the cleaner and assembled, such that the filter disposed inside the filter module may be easily cleaned or replaced.
