London: Researchers have recently developed a washing device, named Dolfi, which uses ultrasonic tech to clean clothes.
The device, which might make washing machines a history, promises to turn any sink into a mobile washing machine, the Daily Express reported.
The device is no bigger than a bar of soap and it claims to wash clothes as well as a machine in 30 minutes by zapping them with ultrasound technology.
All it requires is sink full of water, dirty clothes and detergent. Then its powerful soundwaves emitted by a transducer travel through the water forming tiny, high-pressure bubbles that blast dirt from the clothes.
