Abstract
A vacuum cleaner includes a circuit breaking control device responsive to the correct positioning of a dust collecting bag in order to ensure that the vacuum cleaner is not operated without the dust collecting bag. A visible light may be provided to signal that, although the vacuum cleaner main power switch is on, the motors in the vacuum cleaner are not energized because the dust collecting bag is not in place.
