This is a hand-operated washing machine that is a perfect tool to wash, blankets or other horse or rider apparels. The hand propulsion up and down causes agitated water passage back and forth through the fabric to clean yet not damaging it in anyways. It works exactly as a regular washing maching except that it does not require any machine. This is a perfect handy tool in the barn or on long trail rides. The other great benefit is that it requires minimum detergent and water.
