If the people behind the Dolfi's claims are true, then your next house might not need a laundry machine. The Dolfi is an unreleased gadget that could transform any sink into a fully-functioning washing machine.
Simply fill your sink with water, add some laundry detergent and then insert a Dolfi machine. From there, the Dolfi would unleash a torrent of ultrasonic sound waves that mix everything up.
The Dolfi was designed by German entrepreneur Lena Solis. What inspired the gadget? Solis explained:
"The idea of Dolfi came after a few terrible experiences with laundry during my extensive travels."
