ABSTRACT:
A structure for a vacuum cleaner for confirming whether a filter is mounted into a vacuum cleaner includes an interlock mechanism. The vacuum cleaner includes a cover including a discharging port for discharging air, and configured to cover the first end of a receiving space. The cover is mountable on the receiving space and an interlock mechanism is mounted on one of the cover and the receiving space. The interlock mechanism is configured to prevent the cover from being mounted on the receiving space if no filter is mounted in the receiving space. The interlock mechanism is configured to allow the cover to be mounted on the receiving space if a filter is mounted in the receiving space.
