Why feed each piece of produce by hand, when the Sana 878 will do it for you? Just fill the large 2-liter automatic hopper with your favorite produce, turn on the juicer, and walk away. The dual-bladed system sorts, cuts, and feeds the produce in the juicer, giving you time to do other things. A circular opening in the lid lets you throw in other ingredients without opening the lid. The included vacuum storage pump and container keeps your juice fresh up to 72 hours.
