Abstract
A downsized vacuum cleaner whose filter is less likely to be clogged. An electric motor 2 and a fan 3 are provided within a cleaner body 1. A dust collecting section 16 is formed annular so as to surround the circumference of the fan 3. A filter 12 for filtering dust is mounted at an inside peripheral face of the dust collecting section 16 and dust separated by the filter 12 is collected in the dust collecting section 16. A flectional portion 35 is formed at an upper end of a suction tube 32, facing the dust collecting section 16 so that an airflow flowing along a peripheral direction of the dust collecting section 16 is generated. This causes comparatively larger-sized dust to be pressed, by a centrifugal force, against an inside wall of an outer peripheral side of the dust collecting section 16 so that only small-sized dust is filtered by the filter 12, preventing the filter 12 from being clogged.
