Self-Service Car Washer / 1.01 Automobiles/Vehicles/Bike

Self-Service Car Washer

“Environmental Assistant - Self-Help Car Washer” is a manpower-driven self-service car washer. Unlike traditional car washers with high energy and water consumption, the environmental car washer isn’t electricity-driven. Using the air pump theory as the theoretical basis, it works through the air compression bag and compresses the air into the air pump, and works by air pressure and squeezing the water into the brush set with turbine. The brush is rotated by power getting from the water rushing the turbine, then it will wash automatically, effectively avoiding arm ache caused by hand wash.
