Abstract:
1. A vacuum cleaner comprising: a main body having an electric blower for generating a suction air flow; a dirt collecting case installed at an intake side of the electric blower, communicating with a suction head which draws dirt containing air into the main body; and a dirt compressor for reducing a volume of dirt accumulated in the dirt collecting case through the use of the suction air flow, wherein the dirt collecting case includes: a separation chamber wherein dirt is centrifugally separated from the dirt containing air; a first air intake member provided in the separation chamber and communicating with the electric blower; a dirt collecting chamber in communication with the separation chamber arranged to accumulate the dirt separated in the separation chamber; and a second air intake member provided in the dirt collecting chamber and communicating with the electric blower; wherein the dirt compressor guides the suction air flow toward the electric blower through the first or the second air intake member selectively to thereby compress the dirt accumulated in the dirt collecting case when the suction air flow is guided through the second air intake member.
