If you want really fresh and nutritious drinks, get a high-power blender. Not only do they operate on any fresh fruit and vegetable, they keep all the fiber in the produced drink. So less sugar percentage (especially if you have lots of vegetables in the mix) and vs. eating the fruit directly, the high power mixing helps digesting all nutritients much better than just chewing can.
As a bonus, you can use it for many other cooking tasks (soups, sauces) but also you can do things like blending a good amount of ice with the fruit to get a cold and icy drink and my favorite is just to mis a scoop of natural yoghurt with frozen berries (add sugar, cream, a shot of bourbon to your taste) to instantly get a nice ice-cream like dessert.
(Disclaimer: there are a very few vegetables which should be eaten cooked only, so don't use those for a smoothie, others only in reasonable dosis, so some very basic reading is recommended)
