Hey Dirk, it does seem like a simple programming tweak could take care of it. But at Marina Pools, they say they virtually never hear about this problem (my situation might have been their first). It seems consumers aren't hollering about it.
I think it may have to do with the depth of my bench, which has 14" of water on it. It was mentioned above that a Maytronics robot didn't shut down in 24" of water, and Flipper has no problem negotiating my normal steps; the top is pretty wide and has maybe 5" of water. So there may be a fairly narrow window of depth of water where Maytronics models get stuck.
Seems weird. I've only owned one pool (which has two benches that would foil a robot, apparently), but I've seen enough pools here, and they all have benches and steps and many have shelves. Just seems weird that this issue isn't so common that it wouldn't have been addressed.
But I'm still trying to figure out why any of a hundred products we all use everyday never work like we think they should! And my first thought is: didn't the guy that designed this ever try it out himself?!? I want to watch a TV show where they bring on the CEOs of companies that manufacture these products:
"Hey Mr. Acme, let's see you open that box of crackers without shredding the top."
"Yo Tim, can you show us exactly how to get our iPhones to check for mail?"
or the classic:
"Can you please walk us through the assembly of this [fill-in-the-blank] using the instructions you provided?"
Yes, I realize I just revealed I'm old!! 🤪
