I hate doing dishes. My sink is filled with them; I put their scouring off as long as possible, at least until the fungal growths begin to bloom and wreak havoc with my sinuses or the first-generation egg sacks burst open and a deluge of thousands of skittering insects come swarming from my sink. Then I do the dishes… usually with a flamethrower.
So for me, ultrasonic dish cleaning gadgetry is the Holy Grail of Tech. I just want to be able to lazily wave a magic cleaning wand over my sink and have everything glitter in the sun. The SMV-08AM megasonic cleaning device from Coway won’t manage anything as grand that, but they do promise to eliminate “dirt and agrochemicals” from the surface of just about anything, using only water and sound waves. The water is even cleaned before it is distributed by a patented “P-Filter,” which I’m sure will come as a relief to everyone. No price, unfortunately, but laziness is expensive.
