Most Vitamix blenders lack the shredding and slicing disc that food processors usually come with, so you can't use them in situations where you want to thinly slice vegetables or shred cheese. Certain Vitamix blenders can handle more complex tasks, like processing chunky salsas and dips on a low-speed setting. But in general, Vitamix blenders cannot double as a food processor. That said, the Vitamix brand has launched a food processor attachment that you can connect to Vitamix blendes. The one downside is that this attachment only works with more advanced models.
