ABSTRACT:
A vacuum cleaner assembly (10) is disclosed that includes a main housing (12) having an inlet (14) and an outlet (16). A motor (17a) is disposed within the main housing (12) between the inlet (14) and the outlet (16) for providing motive force to a cooling fan (17b), a blower (17c), and a separator (22). The cooling fan (17b) is mounted within the main housing (12) above the motor (17a) to circulate cooling air around the motor (17a). The blower (17c) is mounted within the main housing (12) below the motor (17a) for drawing air into the inlet (14) and exhausting air outwardly through the outlet (16). The separator (22) is mounted below the blower (17c) for circulating the air and water bath (20) within a water bath pan (36) and providing, in combination with the water bath (20), a primary filter for filtering the air prior to exhausting the air outwardly through the outlet (16). A second filter (24) is a high efficiency 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) and before the outlet (16) for additional filtering of the air prior to being exhausted. The second filter (24) is 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 (24).
