A wet-type electric cleaning apparatus for inducting outside air, which contains dust, into a liquid stored in a liquid tank 10 by reducing the pressure inside the upper space 42 inside the liquid tank 10 . The cleaning apparatus includes an intake passage 32 having a discharge port 26 for discharging the dust-contained outside air as a swirling flow, from the central bottom inside the liquid tank 10 , a disc-shape guide panel 34 provided above the discharge port 26 with its radius gradually decreasing from the vicinity of the center of the liquid tank 10 , forming a ring-shaped gap 36 between itself and the inner surface of the liquid tank 10 to allow air to pass through the ring-shaped gap 36 into the upper space 42 in a form of a swirling flow, and an exhaust passage for exhausting air from the upper space 42 of the liquid tank 10.
