Cow Wash

It looks like cows wandered into a car wash, but this brush is actually made for them:

The industrial-sized device features a huge swinging cow brush similar to those used to clean vehicles.
It is fixed inside a milking parlour or a barn and herds of cows can pass through and receive a thorough clean one at a time.
Designers DeLaval claim the grooming device makes cattle more healthy and stops the spread of disease.
