I don't own a robotic vacuum, but two racks. They seldom end up in the exact same position every time, are frequently moved between rooms depending on state of drying, weather, and so on. Not to mention the kids.

I can't imagine spending effort exactly mapping the location of a rack, a passive/permanent solution like the one in the article is just right.

It doesn’t matter where I put them in the Roomba app, it still ignores them. Then it goes out into the deck and makes a racket while it looks for things to get stuck in/on/over/under.

I’ve remapped the house and the problem persists.

Some do, but not all of them. We have the cheapest Eufy one and it doesn't have no-go areas. I just lift wires and have screwed a piece of wood underneath the shoe rack where it sometimes gets stuck because the floor isn't level. The piece of wood stops it heading under there.
