ABSTRACT:
A vacuum cleaner comprising: a main body having a dust collecting chamber and a motor chamber; a cover for the dust collecting chamber; and an inlet pipe formed on the dust collecting chamber. A lever is provided within the dust collecting chamber, the lever being swingable between a position where one end of the lever is positioned between an opening edge of the dust collecting chamber and the cover to prevent the cover from closing and a position where the lever enables the cover to close. It is not possible to attach the cover to the cleaner in the state where the dust collecting bag is detached so that it is possible to securely prevent misuse of the cleaner in the state where the dust collecting bag is not attached.
