This is by far the worst toilet I've ever owned. After the first two weeks of use, it has clogged almost every time. The design seems to be the reason. There is NO WATER that actually sits in the bowl, only a little bit at the trapway opening (pictured), and there is a horizontal ledge (pictured) at the trapway opening, that (sorry for the unavoidable gross talk), along with the dry bowl, causes stuff to get caught on that and then get folded in half against the back of the trapway opening, resulting in a clog at the opening (which is no fun to remove), and it’s not from paper, which is always sparingly used. The toilet has to be flushed WHILE going and after, to try to avoid clogging, which doesn’t always work….There go all the water savings.
Then, there’s the sticking/smudging & smell problem. Because of the dry bowl, stuff gets stuck to the sides & back of the bowl, which doesn’t get flushed away even after 5 full flushes. This toilet has needed to be cleaned with paper, or a brush, after EACH use. The “Tornado” flush isn’t really that powerful, and it swirls around the bowl like any other swirl-type flush. It also misses a portion of the bowl just above the trapway opening (pictured), and that’s where the most persistent sticking/smudging occurs. In our experience, there is NO functional difference in Toto’s proprietary cefiontech glaze vs the glaze that was used in other brands owned previously (Kohler, American Standard)...stuff is going to smudge and stick to any dry surface, and this toilet does NOT wash it away any better. The other toilets at least had water in resting the bowl to help w/ this issue, and also to help avoid clogs. Also, because of no water in the bowl, there is a horrible smell during and after use.
A toilet should not be a source of stress before, during, and after use!
UPDATE:
After a month, I drained, dried, and applied Spray wax (Turtle Ice), which helped a little, but VERY LITTLE.
I ended up taking it to Habitat For Humanity, and while I was there, bought a used (but very clean) American Standard (2 1/8' trapway) for $25. I cleaned and waxed it, and it's working MUCH better than the Toto. It doesn't clog, and because water sits in the bowl, there's no mess left after flushing.
