The two models are very alike, but the C7000 is a newer version of the B6000. The C7000 comes with a hopper (a flat-top funnel), that can be placed over the feed chute opening. The hopper makes it easy to place small items, like grapes, into the juicer. The C7000 also comes with a pulp strainer to place over the juice cup. This filters out any extra pulp within the juice. The B6000 does not come with these accessories. Furthermore, the C7000 contains internal updates to the juicing parts for better yield and efficiency. The B6000 is our original whole slow juicer model, and is now available for about $50 less than the C7000 juicer.
