As electricity and the storage of it has both been solved in the device vacuum operation is done by an ultra light weigh electrical engine. It works as a vacuum cleaner. The bags can be ordered together with the suitcase. The vacuum bags with the desirable amount of clothes can be closed by hand as usual and the circle slot should be joined to the slot of the pump.
