A vacuum cleaner assembly having a separator of reduced dimensions. The separator is operated at preferably between about 20,000 rpm-30,000 rpm and includes a reduced number of slots formed therein. A labyrinth sealing plate and fan adapter are secured to an upper end of the separator to prevent water and dust and dirt particles from bypassing the separator during operation. The separator is preferably spaced from about 1.0 inch to about 6 inches above the upper surface of the liquid in a liquid reservoir of the vacuum cleaner assembly with which the separator is used. The separator, because of its reduced dimensions and weight, is able to be driven with a small conventional, and less costly and less powerful motor at a higher speed than previously designed separators without suffering breakage. The higher speed of 20,000-30,000 rpm helps to prevent the airflow through the separator from being impeded because of the reduced number of slots. The labyrinth sealing plate coupled to the separator helps to provide a labyrinth seal to prevent water and dust and dirt particles from bypassing the separator and entering the interior of a blower housing. In an alternative embodiment a spider member includes a circumferential raised shoulder portion which cooperates with a circumferential groove formed in a lower surface of the blower housing to form a labyrinth seal.
