What's the main difference between "mixer" and "juicer"? Aren't they both make juice?

Ah! There is a slight difference. You make juice in a "juicer" by putting the fruit or vegetables in it, and then it gets compressed. Once compressed, the juice comes out of one side, leaving behind the meat of the produce. The juice has been extracted from the produce. Whereas, a "mixer" or "blender" blends it all together into a liquid form. They are not separated. Ex: This smoothie wasn't mixed properly. There are still bits of fruit in it. Maybe I should blend it again. Ex: I put so much fruit in the juicer! But I only got half a cup of juice from all of that fruit.
