I washed my Toyota Prius with 8 L water, water pump

I have made a submersible water pump using a mini DC 130 serials motor. What can we do to use this mini water pump? I use it for watering the plants. Also, I washed my Toyota Prius with only 8 L water. It is good to save energy, money, and source. Let’s save the earth from now. Of course, you may use more water, my car has not been cleaned for 3 months. I have traveled about 1000 Km in three months. But it is still not so dirty because Japan's road is quite clean, I think. Anyway, you can save water because it uses a very small but high power water stream. https://youtu.be/ZRmhvMqz2dc
