A cleaner using a heating, ventilating, and air conditioning (HVAC) module is provided. The cleaner connects a ventilation fan for the HVAC module and a suction fan for vacuum cleaning to a single motor to independently drive the ventilation fan when the HVAC module is operated and to independently drive the suction fan when vacuum cleaning is performed. Accordingly, the number of components and production cost are reduced and, simultaneously, package assembly capability is improved.
