Abstract: A vacuum cleaner blows hot air to dry objects to be cleaned and prevent adhesion of the objects. The vacuum cleaner includes a first bottom air inlet, a rear air outlet, a housing having an air passage for guiding first air from the first bottom air inlet to the rear air outlet, and an electric blower fan in the air passage to suck up the first air. The housing includes a headwind inlet that inhales second air from outside and guides its flow as a headwind against the flow of the first air preventing adhesion of objects to be cleaned. A bottom air outlet discharges hot air heated when passing by the electric blower fan. A flow direction changer changes the direction of the hot air to the rear and/or bottom air outlets. A user selectively controls the flow direction of the hot air toward the objects to be cleaned, thereby drying them. A headwind blows against the flow of air inhaled into the housing and prevents adhesion of the objects to be cleaned, thereby improving usability.
