    Hi we remodeled our home and bought 3 of the Aquia iv toilets They work very well Except poop sticks to the inside of the bowel and have to scrub with a brush to get it cleaned off even though they claim to have superior finish to keep bowel clean. What can I do to prevent this as its embarrassing for guests to use this toilet and a constant fight for us to scrub after each big job.
