1. A dust collecting apparatus which is detachably coupling with a vacuum cleaner, comprising:

  • a dust canister body, a part of which becomes an exposed side exposed outside a cleaner body upon mounting in the cleaner body, and which comprises a first dust separating chamber for separating large-sized dirt from air flowed in through an inlet port formed at one side thereof by using inertia and gravity, and second dust separating chamber, which is isolated from the first dust separating chamber, for collecting fine dust from the air passing through the first dust separating chamber;

    a cyclone body having a cyclone chamber which is in fluid communication with the first dust separating chamber and separates the fine dust from the air passing through the first dust separating chamber by using centrifugal force generated when the air is rotated; and

    an outlet pipe which is protruded from lower surfaces of the first and second cyclone bodies to upper sides of the first and second cyclone chambers,wherein at least a part of the exposed side of the dust canister body is made of a transparent material so as to simultaneously see through the first and second dust separating chambers, and at least a part of the cyclone body is made of the transparent material to see through the cyclone body.
