IMPROVED VACUUM CLEANER

摘要

A vacuum cleaner assembly (10) comprising 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 separator (22) is mounted below the blower (17c) for circulating the air and water bath (20) within a water bath pan (36) and provides with the water bath (20) a primary filter for filtering the air prior to exhausting the air outwardly toward the outlet (16). A second filter assembly (24) is also provided including a high efficiency filter (100 or 100a) for filtering microscopic dust and dirt particles that escape the primary filter (22, 20) and is disposed before the outlet (16) for additional filetring of the air prior to being exhausted to the atmosphere.
