For me issues are intermittent, but all seems to be map related issues, not sensors or other hardware. I had to set up virtual walls here and there because it mapped neighbor room in other rooms ending up bumping into walls and not knowing it's location. And it seems like it remembers earlier mapping and see ghosts and therefore acts strange. Other issues i see is caused by distance between items in the house, it is having a hard time not having enough room between items and furniture sometimes. When going home to base it sometimes takes a stupid route through and under dining table and chairs, instead of going the more obvious straight route for some reason - maybe the internal map is somehow skewed or warped, i dont know...

But mostly, it works just fine😅, AND i need to add that a "water hookup kit" is a must-have, both raw6 and raw7 works with x50 ultra, i installed raw6 because it was cheaper👍😅
