Abstract
A cyclonic vacuum cleaner with simple structure, low airflow leakage, excellent maintainability, and less possibility of littering a floor in the case of dumping dusts or care of the cleaner. A cyclonic portionof an approximately cylindrical shape, having a bottom, an introducing portionfor introducing dust-laden airflow to the cyclonic portionand a reinforcing ribprovided on a lowermost end of the dust-collecting portionfor allowing it to stand on end, are formed into a one-piece structure. Thus, the structure from the introducing portionto the cyclonic portioncan be simplified and the possibility of airflow leakage can be reduced. Also, maintenance of the cyclonic portionand the introducing portioncan be easily performed through the detachment of the dust-collecting portiontogether with the introducing portionFurther, a floor is less likely to be littered with dusts collected within the cyclonic portionby allowing the dust-collecting portionto stand on end with the help of the reinforcing rib
