I had the TOTO Aquia for a while, and then changed it for a TOTO Double Cyclone.
The Aquia was pre Ostomy bag, and the double cyclone was during the time I had the Ostomy bag installed. I know the double cyclone works very well. And I'm sure the Aquia would too.
I did find a lot of bowls that were horrible with the Ostomy bag.
I didn't care for pressure assist bowls. Lots of water for the siphon jet, but not always rinsing in the right spot, the front portion of the bowl.
With some bowls, when you emptied the bag, it would just stay there looking back at you. The combination of the CEFIONTECT finish and the double cyclone just swept the bowl clean. There were times I was so glad to be back home with a toilet bowl that worked the first time.
I encountered some bowls that would take five complete flushes with the handle held down. That was about 15 gallons of water and waiting for that many refills before I was done with the bathroom. Talk about being embarrassed camping out in the bathroom that long.
The old Kohler Ingenium was bad.
Some of the Flushometer bowls were very bad, sometimes putting no water near the end of the bowl. It was a wonder that hospitals and clinics would have such bad bowls to use when they knew that customers with Ostomy bags had to use them.
Having an Ostomy bag was a wonderful way to test bowl wash. I no longer have that "advantage" as mine was removed in November of 2011.
It did make swimming in the Ocean interesting, and ski racing with one kept me a little cautious.
It was pretty convenient in some ways. I mean sometimes you just lifted up your shirt and emptied it. Great for hiking.
So if you have an Ostomy Bag, by all means, pick up a TOTO with double cyclone.

My girl friend had a Glacier Bay when I met here, and of course I installed a Drake II over there. Huge difference!
