Roomba j7 lost: add landmarks/beacons?

[kconover]

I have had Roombas since the beginning. I have a j7+ now. It has a problem of getting lost and wandering into other areas of our (big) house): not being able to find its nest. It navigates by vision: I keep reviewing (and submitting) my interpretation of questionable things it sees, using the app. But it still keeps getting lost. Has anyone tried putting up visual landmarks (or beacons of some sort) to help a Roomba find its way around?

I don't have much knowledge beyond the i7, I will look into this when I have time if no one else responds.

The j7 navigates with a camera and a headlight, and unlike my late, lamented i7, has a recessed camera lens that protects it from scratches from bumping into things. My i7 front got so scratched from running into things it was effectively blind. So th j7has better vision.

I tried putting label tape with "Nest! Nest!" on the sides of its nest but that didn't seem to help. It still has trouble finding its nest, sometimes when it's very close to it. Other times, I find it wandering around other parts of the house looking for its nest. I was thinking about putting some sort of really-easy-to-see and distinctive labels on a few things in the house at Roomba level. Unless using one of my old "lighthouse" devices as a beacon.
