    摘要: A vacuum cleaner assembly (10) includes a main housing (12) having an inlet (14) and an outlet (16). A motor (17a) is disposed within the main housing (12) for providing motive force to a cooling fan (17b), a blower (17c), and a separator (22). The separator (22) circulates the air and water bath (20) within a water bath pan (36) and provides, in combination with the water bath (20), a primary filter for filtering the air. A second filter assembly (24) is also provided preferably including a high efficiency filter (100 or 100a), or HEPA rated filter, for filtering microscopic dust and dirt particles that escape the separator (22) and water bath (20) and is disposed after both the water bath (20) and the separator (22) for additional filtering of the air. Alternatively, it may be a non-HEPA rated filter (101). The second filter assembly (24) may also include a third filter element, which may be a carbon impregnated filter (110) for absorbing or trapping odors and is disposed in the air flow path after the second filter (100, 101, or 100a). The second filter (100, 100a or 101) and third filter (110) element are secured in a frame (112) as part of the second filter assembly (24). The second filter (100, 101 or 100a) and the carbon impregnated filter (110) within the frame (112) are disposed in a recess (26) which is integral with the main housing (12) allowing for direct and efficient flow of the air through the water bath (20), separator (22), and second filter assembly (24).
