A horizontal axis washing machine having a front opening clothes containing rotary basket with a plurality of elongated internally mounted baffles for agitating items within the basket during a washing operation. The baffles each have a solid outwardly extending rib which has a nonlinear curved configuration for defining a plurality of water lifting and agitating cavities on each side of the baffle. The cavities on one side of the baffle are effective for lifting and agitating wash water with a vortex movement as an incident to rotation of the basket in one rotary direction and the cavities on the opposite side of the baffle are operative for lifting and agitating water with an oppositely directed vortex movement as an incident to rotation of the basket in an opposite rotary direction.
