Samson has recently changed the model number for what was formerly the 9001 in BLACK. The Black 6-in-1 model is now called the 9002. This is identified as such on the juicer itself. Note the retail box makes reference to the 6-in-1 without any model # referenced. According to Samson this was done to bring continuity to the product line. So the models are now as follows:
9001 - Ivory Standard 6-in-1
9002 - Black Standard 6-in-1
9003 - Ivory Advance
9004 - White Advance
9005 - Black Advance
9006 - Chrome Advance
