A tiny device could be about to revolutionise the way we clean our clothes. 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. Powerful
ultrasonic soundwaves are emitted by a transducer which travel through
the water, forming tiny, high pressure bubbles which implode to create
strong jets of water that remove dirt.
The device washes the clothes without any need for scrubbing or wringing in just 30 minutes. Dolfi is so small it can be carried around in a bag for use at home, hotels, or even at work. And
its creators claim that unlike a washing machine, which can damage
clothes, the ultrasound leaves fabrics completely in tact so they can be
washed over and over without deteriorating.
