The water level on the clean side of the drum returns back to its normal clean level.The dirt is caught in elongated slots composite screen panels a little like how a water wheel works inside the drum this lifts the dirt out the water up and over the chute and ejected to waste through the waste chute. This cleaning process uses about 1.5 ltrs of water.
