Ultrasonics in the home

I woke up 6am today with a new idea to add ultrasonic vibration to vacuum cleaner heads to improve cleaning efficiency. I suspected it must already exist, and wasn’t wrong. Oh well. I also discovered this blog is far from unique too. That idea appeared on halfbakery, which is a fun visit: http://www.halfbakery.com/idea/Ultrasonic_20Vacuum.

Ultrasonic cleaning itself is very old. My very first job application in 1981 took me to visit ultrasonic cleaning departments that were already old. So actually, the idea to add it to other cleaners is pretty obvious really. However…

I haven’t yet seen any ultrasonic generating balls that you can add to washing. It would be pretty easy. You make some specially shaped capsules that rumble round with the washing and they transmit ultrasound as they go, helping to liberate dirt and reducing the amount of detergent or heat needed. A simple transducer and battery, so  should be pretty cheap. They would be recharged of course just by leaving them on an inductive plate.
