Washing Machine Concept Uses Robot Fish to Clean Clothes without Detergent

Industrial designer Chan Yeop Jeong from Korea has created a washing machine design concept as part of the Electrolux Design Lab. Pecera washes clothes without detergent, instead using robotic fish that eat people’s dead skin cells and dirt inside the clothes.

The collection of robot fish (called ‘Dofi’) offer an effective and sustainable way of removing dirt and cleaning clothes. They were inspired by doctor fish, which can make people’s skin clean and healthy by feeding on dead skin or an affected area. The Dofi run on hydroelectric power and clean garments by detecting dirt with a tiny embedded camera.


Their sucker-shaped mouth washes the clothes by easily eating the dirt, as the alkaline liquid jelly of each Dofi splits and absorbs dirt molecules of fiber sustainably to clean it. When the jelly touches the fiber, it loosens the coherence between the fiber and dirt on the clothes to split, feed on, and absorb it.

While there is concern over oxidation and discoloration of fiber when using detergent, this eco-friendly way of washing using the alkaline liquid jelly prevents oxidation and discoloration of fiber, so consumers don’t have to worry about damage to their textiles. As this method doesn’t use detergent, it is suitable even for the most sensitive people, and there is no need for multiple washing cycles as the first layer spin-dries and drains off the water.


Unlike conventional washing machines, Pecera’s unique and modern design enables the consumer to put the machine anywhere in their house. It obtained its design motif from nature and ponds, and allows consumers to use the product long-term without getting tired of the design.

Pecera offers a simplified washing process and lets consumers enjoy watching the Dofi robots when they are doing the laundry. As the machine doesn’t use detergent, it will mean a reduced cost, and consumers who have sensitive skin will be happier and healthier.
