An ultrasound device called Sonic Soak has been shown to be more efficient than a washing machine in cleaning and removing germs and bacteria.
sonic soak it is equipped with a powerful ultrasound technology with 50.000 vibrations per second which makes it the perfect cleanser for cleaning. It does not need soap, and works by breaking down bacteria on a microscopic level.
Sonic Soak allows precise and more environmentally friendly cleaning, consuming less energy than traditional washing machines.
The device did the history of crowdfunding raising almost € 1 million (¥ 117 million) in Japan and $ 4 million on Indiegogo.
Take a look at this demonstration video to get an idea of its features and capabilities.
How the ultrasonic cleaner works
The device sends ultrasounds through the water to generate microscopic cavitation bubbles. These cavitation bubbles pass through clothing, or land on objects, then implode and create pressure that immediately eliminates dirt and contaminants.
Sonic Soak is the only device that can clean virtually anything that fits into a container with water (still no ultrasonic floor cleaner, who knows in the future).

From the company website: "Whether it's a business trip, a family camping vacation or a vacation, it's the perfect portable cleaning device for all cleaning needs"
