Turnwasher / Portable dishwashing machine


Turnwasher is a portable pocket-sized dishwashing device, which doesn’t require any water, detergents, or even any need to use your hands. Stick it to the edge of the dishes, press the start button and, Turnwasher will make a circular motion automatically, just like those graceful discs in an old-fashioned CD player. It makes good use of its built-in high-pressure steaming function, to rapidly dissolve stubborn grease whilst simultaneously absorbing the dissolved oil, via vacuum ports, into the collection box at the rear. After frequent use, you just need to remove it and simply clean it.
