Many juicers have two stages: Shredding and juice separation via pressing or centrifugal force. The centrifuge approach works surprisingly well, the pulp that comes out of a good one is quite dry, all the juice is gone. It yields a lot more juice out of a carrot than you'd expect. This "press" simply does the last step in juicing. The hard work of shredding is already done.
