Abstract
A vertical axis washer is provided with a rotatable wash basket that has one or more inwardly directed baffles, but no central agitator structure. Surfaces are provided in association with the baffles, which may be in the form of ramps on the bottom wall of the basket, to cause the fabric load within the washer to move up the side of the basket wall and to slide along the baffles in a swirling motion as the basket is accelerated and decelerated during the washing cycle, which causes the fabric to be flexed and rearranged in the basket. This washer construction is particularly suited to be used in conjunction with a concentrated detergent solution wash cycle.
