Even the worst toilets I pull out and toss will flush golf balls.
It's an amazing thing to see, round objects bouncing their way down the pathway and down the drain. It's too bad nobody poops marbles though. I will have to keep that in mind though if I start doing service work for robots that perhaps in the future will simulate human activites by being programed to poop marbles.
The real human thing we mainly deal with is paper. I'm not a fan of Charmin with it's almost cotton like material. A bidet seat solves some of that. In many countries, they wash mainly with water, very little paper. You won't see many trees there, so they think it rather silly how much paper we use. For myself, living in the Seattle area, I love the warm seat of the bidets and Washets. I'm getting a little spoiled I guess.
Yes, I've also had pressure assist toilets in the home to see how that all works. I have one at my mothers place too in one bathroom. The one I had in my home got me in trouble with the women. It was a Consumer Reports "
Best Buy" that the women hated and were afraid to use. I guess the men in white coats loved it with all it's silly noise, but lacked the ability to flush paper. It was great flushing sponges and baby wipes. Two things I don't allow in my home to be flushed. But I guess the men in white coats do. At least in their warehouse they fit up for testing with silly items so they can write about what I do for a living and keep their hands clean.
I will say that the Kohler pressure assist is my favorite of the pressure assist bowls. They did a good job with it. And I do recommend it for those that need that kind of power. It has it's place.
Another toilet that I worked on today, one more Consumer Reports "Best Buy", The American Standard Champion was flushing rather poorly when I first got there. Unlike the TOTO Ultramax, holding the handle down did nothing. The flush valve for the Champion leaves a lot of water in the tank. With the imperfect adjustment, the homeowners were flushing several times to get things to go down. I made some adjustments and was able to get it to flush with a flip, but I will have to say, the Ultramax has more options and would be my choice. But then, I have installed hundreds of these things. I have to deal with the end user. I don't get to try something "one time" and call myself an expert. I don't have a white coat. Maybe I should get me one of those dang white coats too.
