A new, portable ultrasonic laundry device called Dolfi is able to wash your clothes easily using ultrasonic sound waves. All you have to do is put your clothing in a sink, fill it with water and detergent, add the Dolfi and turn it on. In 30 minutes, your delicates will be clean.
Dolfi uses ultrasonic technology to create sound waves that move through the water and create “miscroscopic high-pressure bubbles.” These bubbles then implode to create “millions of micro-jet liquid streams” that wash away dirt. The Dolfi is no bigger than a bar of soap, yet it transforms any wash basin into a washing machine. To use it, a person drops the Dolfi into a sink full of water, dirty clothes, and laundry detergent. The device washes without any need for scrubbing or wringing in 30 minutes.
