Drunken wandering, incomplete cleaning/mapping

I have the L20 vacuum/mop combo (Rosie). I won this from my employer 02/2025, and have been using it almost daily since. All of a sudden about 2 wks ago she started wandering aimlessly, going in circles, looking like a drunken robot with a brain injury that doesn’t know what to do, draining the battery and didn’t even finish “cleaning” a single room . She doesn’t finish the task, ignores rooms, tells me a room is inaccessible (door is WIDE OPEN), I’ve even gotten a notice about my WiFi signal. Nothing has changed in the house, literally everything that uses WiFi connection has no problems. My firmware says it’s up to date. My phone is up to date. I sent a ton of videos and photos to tech support last week, and they recommended (before I could send photos/video) to remap the house. Today I did, and she spent literally ONE MINUTE mapping ONLY the room the base is in. She detected other areas but never left the first room. I’m becoming VERY DISAPPOINTED in this product. I might not have spent my own money, but for roughly $1400 (Amazon list price when I got it), I shouldn’t be having these issues…. Especially when she worked just fine for over 4 months. YES, I Already cleaned EVERYTHING from the robot to the base station. Checked my WiFi router is working properly. Dreamer firmware says it’s up to date with latest version. Deleted map, ATTEMPTED to remap and she “completed” it after literally 1 min, missing about 80% of my house (no obstructions).
