Query: Wastes time, wastes vegetables

I've never owned a juicer before, so I can't offer a comparison between this and any other model. I can say that this takes about 15 minutes to clean after every use, one serving of juice consumes about $5 - 7 worth of vegetables, and probably about half of all the vegetables put into it are wasted with no juice extracted. An enormous mass of vegetable pulp is left over even when juice is successfully extracted. Compared to simply eating the vegetables and drinking water or tea, using this machine is stupendously wasteful.
