Abstract (en)
An inlet means (200) with multiple suction ports and a vacuum cleaner (100) in which the inlet means is disposed are provided. The inlet means (200) includes an upper casing (201) having a secondary suction port (231) formed therein, a lower casing (202) engaged with the upper casing. The inlet means (200) further has a main suction port (203) formed therein and a shutter (240) formed in the upper casing; a secondary flow path (230) and an shutter flow path (210) are each formed between the upper casing and the lower casing, the shutter (240) opens the secondary suction port (230) and closes an upper end of the shutter flow path (210), when the vacuum at a lower area of the lower casing is increased. Accordingly, a constant contact force is maintained between the inlet means and the surface being cleaned.
