I did some more testing as you can see above. I have definitely confirmed that it is related to the WiFi signal. Would be great if the floor plan was actually stored in the Vacuum so that it could use it locally and not require WiFi while Vacuuming. I guess it is that way so that the app can display the path and where it has cleaned. In any event, here is how I determined this:
First thing I did was cleaned the Vacuum, Lidar, front sensors, edge sensors etc. and did a run. Did not work - still got consfused.
As I indicated I have a TPLink Mesh Network consisting of the Primary Node in my Media Closet at the primary end of the house. I have a second node in the Living Room, which is 1/2 way between the first node and the back of the house. I have the third node in my MBR.
I rebooted the Living Room Deco, which forced the Vacuum to connect to my Media Closet Deco. The signal was great as it is midway. I rebooted the MBR as well - wanted to ensure I was starting from a common point. The only Deco I did not reboot is the Primary one (Media Closet). Now that the Vacuum was on the Media Closet, I turned off the Mesh Technology for the Vacuum and sent it on its way, 1/2 down the hall the signal went from 3 bars to 1 (and was yellow indicating it is a weak signal). At that point the Vacuum started getting confused, spinning in circles and ultimately ended up in my MBR as if the hall magically got extended. I decided turned on the Mesh Technology to see if it would switch, to no avail. Stayed on the Primary Deco. I then stopped the process and decided to have it go to the charger. Again, it started off heading in the correct direction, but ultimately got lost again.
I then Rebooted the Main Deco (Media Closet), this forced the Vacuum to join the Living Room deco (Mesh Technology was on). I then turned off the Mesh Technology and left the Vacuum on the Living Room Deco, and it succeeded. Did not even hickup at all.
So in conclusion:
- Yes it is related to a WiFi signal Issue
- Turning off WiFi Mesh did work. But I did baseline everything again to start from a known state. If you device is not mobile, you can turn off Mesh Technology for that device. However, leaving it on will not hurt either.
- Beamforming is not used and could cause an issue. Unless you have Beamforming+ which allows for older devices.
- Fast Roaming should be on for devices on the move (with the exception of the Vacuum if you can get a decent signal from a central Mesh Node, Like me).
In any event, I finally got a clean run without the issues I have been having. I will see the next time it goes to clean the entire house as that will indicate if leaving Mesh Technology off fully works.
