The Dolfi may be small, but it’s pretty powerful, allowing you to convert your kitchen sink into a washing machine through the power of ultrasonic technology.

At the size of the smartphone, it emits ultrasonic waves, throuroughly cleaning both delicates and normal washing loads weighing up to 2kg.

It takes half an hour to thouroughly wash clothing and other fabric-based items, removing both visible dirt and bacteria, while being extra-gentle on delicates. It’s also super-kind on the environment, consuming 80 times less energy than a washing machine.

Lena Solis, the founder of Dolfi says: “The idea of Dolfi came after a few terrible experiences with laundry during my extensive travel. Inspired by amazing benefits of ultrasound, successfully utilised for years in many industrial and medical applications, we’re excited to bring the advantages of ultrasonic precise cleaning to everyday personal use. I believe that ultrasonic technology will change the way we wash.”

The size and shape of the Dolfi makes it perfect to take travelling with you, so you don’t have to rely on expensive hotel laundry services or find a launderette when you’re on holiday or away on business.

Andre Fangueiro, Dolfi’s product designer says: ““We want people to have more fun on their travels rather than stress about costly laundry service, or spend time searching for coin laundries, or even waste luggage space packing extra clean clothing. With Dolfi, travel will become easier, happier and a lot more fun!”

The Dofi is available to buy from IndieGogo at prices starting from $99 (£66), while those who are a little late joining the party wil have to pay $109 (£72).

At the time of writing, Dolfi had raised $172,000 (£114,000), way beyond its goal of $100,000 (£66,000), with 25 days left on IndieGogo.
