Product description

Washing egg, the appearance is like ovum, and the length is 8cm, the width is 6cm, the height is 4cm, with double physical sealed waterproof layer.
On the rear there’s a very long power cable. Use 5V DC voltage. But it also can work when you insert it into portable power.

The device can be used on any fabric – including cotton, silk, lace and even cashmere – and uses 80 times less energy than a standard washing machine.

The machine is the brainchild of German entrepreneur Lena Solis, who was inspired to design it after encountering problem washing clothes while travelling.

‘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.
The ultrasonic principle of washer means that ultrasonic generator sends vibration signals of high frequency, by transducer it will be converted into mechanical vibration of high frequency and spread into the media –i.e washing solvent.
The ultrasonic wave will radiate forward in different density in washing liquid, and make the liquid flow so as to generate tens of thousands of tiny bubbles with the diameter of 50-500μm .


These tiny bubbles in the liquid vibrate under the influence of sound field. And these bubbles will generate and grow up in the negative pressure zone of ultrasonic vertical transmission, while in positive pressure zone when the sound pressure reaches a certain value, the bubbles will increase rapidly, and then close up suddenly, meanwhile they will creat shock waves, around them they will appear thousands of barometric pressure to destroy insoluble dirts and make them scatter in the washing liquid.
When the particles group is covered by oil and stuck on the surface of washed piece, the oil will be emulsified, and the particles group will peel out, thus it can reach the purpose of purification.


During the process which is called “cavitation” effect, when the bubbles close up, it can reach hundreds of high temperature and transient high pressure of more than 1000 barometric pressure, the continuous transient high pressure will impact the surface of washed piece unceasingly like a series of small “ explosions” so as to make the dirts on the surface and in the slit peel out rapidly, in this way, it can reach the purpose of purifying the surface of washed piece.
