Meet “Dolfi”, a next-generation ultrasonic “washing machine” that fits in the palm of your hand. Designed by Switzerland’s MPI Ultrasonics, the smartphone-sized gadget conveniently fits in any bathroom, suitcase, or purse. No need to splash out for your hotel’s laundry service, rack up dry-cleaning bills, or labor over a sink: The Dolfi promises to clean even delicate fabrics, such as silk or cashmere, with minimal water, energy, and fuss. Harnessing the “power of ultrasound” is easy. Simply place your garments in some water, add a squeeze of detergent, plop in the device, and turn it on. In 30 to 40 minutes, your clothes will be fresh and clean, ready for rinsing and hanging up to dry.


As newfangled as it sounds, ultrasonic cleaning has been around since the 1950s. The technology works by turning electrical vibrations into high-frequency sound waves, which react with any surrounding liquid to create millions of microscopic bubbles. The bubbles rapidly increase in size until they implode on contact with the object being cleaned, creating an effective but gentle scrubbing action that lifts dirt and grime from crevices.

Because of its depth of penetration, ultrasound doesn’t create the wear and tear that comes from mechanical agitation. It also works with just water, although a suitable cleaning fluid enhances the effect.

Unlike its industrial-sized brethren, however, Dolfi is being positioned as the “world’s smallest and gentlest ultrasonic washing machine,” suitable for everyday consumer use.

MPI Ultrasonics plans to launch a crowdfunding campaign on IndieGoGo this month, with projected delivery of Dolfi devices in August. No word on pricing yet.

Update: Jan. 22, 2015
The Dofli is now available for preorder of IndieGoGo at an early-bird price of $99, with free shipping within the United States. Part of campaign funds will go toward dolphin research and welfare.
