Roshing machine / Rolling washing machine

With a brief research on some people’s lifestyle in deprived areas,I found that in many cases the area was so hard to equip electricity and also they are not willing to afford the cost of washing machine and they thought it is not efficient So, they wash their clothes in a very bad position of sitting nearby the rivers outside of the village
This washing machine's mechanism is based on gears power.

Its full mode is about 17 kg and it easily works:
1.Put your clothes in
2.Put the water and washing powder from top door
3.put its cap and start walking
4.after about walking 10 minutes with the velocity of 20 m/s your clothes are cleanily washed
