Video: Working at the cow wash
According to this video posting, farmers in Britain are looking to increase profits with a carwash for cows. The swinging device features a "cow brush" similar to the brushes carwashes use to clean vehicles.
Inside the milking parlors or barns, cows can pass through the area to be cleaned one or two at a time. The designers say the grooming device makes cattle more healthy and stops the spread of disease.
A similar device can be seen at a Connecticut farm here.
