Abstract
A filter barrier or ring fixed to the bottom of a washing machine basket includes a plurality of closely spaced flexible teeth in a circumferential row extending outwardly and downwardly to divide the tub into first and second zones for filtering laundry liquid during a washing cycle. The teeth deflect in response to centrifugal spinning forces to effect self-cleaning.
