That's a pretty interesting machine, but as you point out far too clean! I also noticed that the cow's teats weren't sprayed or dipped with iodine solution post-milking to prevent mastitis. Each cow should also be inspected pre-milking for mastitis, cut or damaged teats etc, and the milk diverted away from the main vat. I think there would still be requirement for human input and monitoring even with this machine. The other thing is this machine seemed quite slow to attach to the teats. Generally, you'd want to get the cows back on the pasture quickly. This system would take half a day to milk any decent sized herd.
