The "double cyclone" technology is not exactly living up to its billing, either. The entire flush basically consists of a gentle swirl of water around the bowl with a lazy gurgle at the bottom. There is absolutely no force behind it at all and anything that gets stuck to the bowl (waste getting stuck to the bowl happens far more with this toilet than any other I've used - not sure why) is not rinsed away, even after multiple flushings. Solid waste requires two flushings EVERY time - the first gets most of it, the second to get all the floating little pieces that are always left behind (sorry to be gross). You then must use a toilet brush to clean what is still stuck to the bowl EVERY time you introduce solid waste. I did not have to do this with my builder-grade toilet - it usually needed two flushings, but took care of everything with the second flush 90% of the time. The Toto rep confirmed that the "double cyclone" is just water entering the bowl out of two sideways holes rather than several under the rim so that the water simply falls into the bowl in a circle instead of straight down. He told me "it's not like there is any extra water pressure or anything".
