Ultrasonic technology is already used in consumer products such as humidifiers and jewelry cleaners, plus commercial electronics that sanitize the likes of medical and dental equipment, so all Dolfi is really doing here is applying a proven method of spiffying and de-germifying delicate items to clothing.
Dolfi calls itself "next generation cleaning technology" for your garments, particularly delicate, hand-wash-only pieces, and articles worn while traveling with limited access to laundering facilities. No swishing, agitating, or spinning is required when you add Dolfi to your washer (or sink or any waterproof container). Once the basin is filled, add clothes, detergent, and your new ultrasonic compadres, and turn Dolfi--not the washer--on to activate the cycle.
When in use, Dolfi glows blue, indicating ultrasound vibrations circulating through the water, cleaning clothes without damaging them. What goes in comes out looking exactly the same, less the dirt, grunge, and sweat. Dolfi promises it won't shrink, tear, or distort even the most susceptible items, such as silk, lace, wool, and cashmere. Its Swiss designers also say the ultrasonic wonder can remove offenders like gym stench bacteria, salt water, and pool chlorine.
Once in place, allow Dolfi to run for 30 to 40 minutes. (There's no harm in forgetting about it or letting it run longer.) And now the downside: after a wash cycle is complete, you gotta rinse and wring the clothes yourself. Or trust your washer to do it without destroying all of Dolfi's good work.
Dolfi functions silently, is compact enough to pack in a bag or suitcase, and consumes about 80 times less energy than a conventional washing machine. The "next gen" launderer seeks crowdfunding on Indiegogo through February 19, 2015.
