Its mini basket does not have perforations on the bottom, only around the top for spinning the water out. See the pic in reply #6 above. FilterFlo recirculation runs for a few mins to fill the mini basket, then the recirculation hose is pinched-off by a solenoid mechanism to stop the flow and agitation continues with a concentrated detergent solution for stain treatment (spot scrubbing). The pinched hose is released for continuous circulation (and mini basket overflow for filtering) during rinse.
