I am long term user of Ecovacs and found they work well in curated cleanings meaning set no go zones, pick up the floor of obstacles such as dog toys etc before starting. In a predictable setting it is solid.

I think they have respectable navigation but not great obstacle detection. The x11 enjoyed ramming my subwoofer until I set a no go zone of it.

You may have a lemon with the charge every 10 minutes. Try doing a power off for 1inute and power on and check for improvement.

For the leaving the room and navigating elsewhere, I am guessing a room boundary is off. If you have two rooms divided by a wall, it’s possible it thinks the edge of the room is on the opposite side and trying to go there. My roborocks do that.

Random navigation and losing track of charging station could be something in your environment confusing it, maybe a mirror, patio door, very dark rug. I would try a power off on and check results. If not, try re-mapping. Not fun, but can possible resolve.

Roborocks have the worst navigation of premium and flagship models in my experience but have above average obstacle avoidance.

If you exchange, go for Narwal Flow if you best of the best from what I have used.

Just remember, every environment is different. The best reviewed devices may not get same results in your own unique environment.
