SHARP Launches of the Portable Ultrasonic Washer (video)

SHARP today announced the launch of the Ultrasonic Washer. Unlike how the name sounds like, it is actually a very compact and lightweight device that removes spot stains on clothing using vibration. Its innovative oscillator at the tip of the device vibrates at 38,000 strokes a second, generating invisible micro-bubbles in water which loosen and eventually remove foreign matter stuck on the fabric.


Check out how it expels soda from the bottle via its super highspeed oscillation.

It is retailing at RRP S$199. I think I need one, especially for my white shirt 🙂 .

Handy SHARP Ultrasonic Washer Cleans On-the-Go

Innovative, powerful hand-held device removes stains from clothing effectively using water

Singapore, 2 November 2016 – SHARP, Asia’s leading electronics appliances brand, today announced the launch of the Ultrasonic Washer, the UW-A1S, which introduces a revolutionary new way to treat spot stains on clothing. The portable device eliminates the inconvenience and worry caused by accidental stains, helping people lead confident lives.

A lipstick smudge on a white top or coffee spilled on a shirt sleeve are no longer a moment of embarrassment with the Ultrasonic Washer. Most stains, whether from food or cosmetics, can be removed by the Ultrasonic Washer on the spot*.

SHARP has designed the Ultrasonic Washer for people with busy lifestyles looking for convenience on-the-go. Rather than pop home to change a stained outfit, forward-thinking consumers can simply carry the compact and lightweight Ultrasonic Washer in their bags for immediate stain removal.

The device is extremely easy to use, and fits comfortably in one hand. SHARP has turned stain removal into a simple three-step process:

  • Soak the stained area in water, add a little detergent for stubborn stains;
  • Turn the Ultrasonic Washer on and trace over the stain; and
  • Rinse with clean water.

The Ultrasonic Washer is also perfect for pre-treating stains before machine washing. The Ultrasonic Washer attacks stains very effectively with ultrasonic waves. An innovative oscillator at the tip of the device vibrates at 38,000 strokes a second. When the tip is placed over wet fabric, the vibrations generate invisible micro-bubbles in the water in a process called cavitation. As the bubbles implode, they loosen and eventually remove foreign matter stuck on the fabric.

Internal tests by SHARP show that stains on shirt collars can be completely removed in one minute, using just the Ultrasonic Washer and ordinary water from the tap, while most stains can be taken off in two minutes. The method is also gentle with fabrics, leaving the delicate fibres intact, whereas handwashing or scrubbing with a toothbrush has been found to fray the fibres.


The Ultrasonic Washer has an elegant frosted aluminium case that is available in three trendy colours: gold, silver or pink. All models are on sale now at a recommended retail price of SGD$199 at all SHARP authorized dealer outlets. For more enquiries, contact SHARP-Roxy Sales Singapore:
