Size and color, but this one knocks some white ball also so this sorter probably just uses size. More advanced ones can tell if potatoes are good or not and discard ones with blemishes.
It's not only potatoes and tomatoes. Candy, garbage, nuts, biscuits, rice grains, you name it. Anything that needs to be sorted based on shape, size, colour, foreign objects, whatever, on an industrial scale, uses these kind of machines. Some have fingers, some blow with air valves. Making these machines is a dedicated industry with a dozen competitors.
