Removing stains from garments using a washing machine is nothing new. But imagine a washing machine which removes stains from clothes without water. Yes, a washing machine without water. Two students - Tan Si Jin Gabriel, Chua Wenni Wendy - from the National University of Singapore’s school of industrial design have developed such a washing machine. This waterless washing machine can remove stains from clothes in a matter of a few minutes.
The AirWash Washing machine uses negative ions, compressed air and deodorants to clean the clothes. The AirWash washing machine has won the Electrolux Design Lab Award in 2005. The AirWash washing machine model is inspired from waterfalls.

AirWash can clean garments of all types. Also less power consumption and no water consumption can surely make this waterless washing machine a wonder. http://www.digi-help.com/toms/waterless-washing-machine.asp
