The TOTO Aquia works fine for bowl wash. It's a washdown bowl, so most of the water comes from the rim and washes down.
Most bowl wash complaints are comparisons between toilets installed before the 90's. For twenty years now, "ALL" bowls have used less water. I did see an Aquia in a restaurant in North Bend the other day, it looked pretty nice.
The Aquia rinses better then the Caroma bowl. We sell a lot of both the Caroma and the Aquia.
Here is a Inax Dover we installed the other day. It's also a dual flush with skirted bowl.
