A vacuum cleaner including a housing having a dust collection chamber; a main body that is movable against the housing between a first position and a second position; a rubbish removal member in the dust collection chamber; and an opening or closing device. When the main body is moved against the housing from the first position to the second position, the opening or closing device opens the dust collection chamber, and the rubbish removal member moves toward an open end of the dust collecting chamber to allow rubbish removed by the rubbish removal member to be discharged out of the dust collection chamber. When the main body is moved against the housing from the second position to the first position, the rubbish removal member moves toward an inside of the dust collection chamber, and the opening or closing device closes the dust collection chamber.
