The Allround Wet hopper, previously called Jacuzzi, is used as a pre-cleaning device. The product falls in the water, where the sticky soil makes it heavier. With air coming from the underside of the machine, bubbles are created which has a cleaning effect. Because of the reduced weight the product comes up and is taken out by a web belt.
