Abstract: PURPOSE: To improve moisture separating efficiency by arranging a sphere between a downward almost conical first cone which is arranged in a suction passage and has a small diameter port on a side surface and a downward almost conical second cone having an intake air port in an apex part in a vacuum cleaner to scavenge dust by bringing intake air into contact with dust sacvenging water. CONSTITUTION: After dust scavenging water 7 is put in a water pan 3, when a fan motor 1 is driven, the dust scavenging water 7 is forced to rotate by intake air containing dirt and dust, and is stabilized when a water level rises. In this case, a scattered droplet generated in a gas-liquid contact part is contacted with and scavenged by a collar shape flange 8, and is returned to the water pan 3. Mist contained in the intake air is collided with and coagulated by a second corn 17 after being delivered from a small diameter port 13 of a first cone 14, and is returned to the water pan 3 through a small drain hole 8. When cleaner main body is extremely inclined, a sphere 19 is attracted to an intake air hole 16 of the second cone 17 by intake air of the fan motor 1, and prevents the dust scavenging water 7 from directly flowing into the fan motor 1.
