Currently crowdfunding on Indiegogo, Dolfi is a small laundry device that uses ultrasonic waves to clean clothes.
Dolfi is simply placed in a sink or container along with the clothing, water and detergent and left on for 30-40 minutes. The ultrasonic waves form tiny bubbles in the water. These implode to create water streams that permeate through the clothing – ridding dirt and bacteria without the need for additional agitation, which can cause damage or distress to garments. This process, known as cavitation, is already commonly used for cleaning items such as jewellery or dental equipment.
The smartphone-sized device is portable enough to be used when travelling, but would also appeal to people living in small homes that lack the space for a conventional washing machine. For more on the rise of compact living, see Design Democracy: Shift.
Washing with Dolfi also boasts a smaller carbon footprint than conventional laundry, using up to 80% less energy than a standard washing machine. Using vast quantities of water and energy, washing clothes is being seen as an increasingly important sustainability issue, with brands and designers considering alternatives that can lessen environmental impact.
