I’ve seen some old posts about this but they seemed to be from last year.
Yarbo has mowed many times already this year pretty much every day it hasn’t rained. Mostly with my M1 because my pro head was having issues. Replacement came this week it’s out mowing now. Right before it went out I also got the new firmware. I go check on it and there a stripes of missed cuts all over the yard! Have never had this issue. Last year with the pro all the cuts so far this year with the M1 never this issue.
The yard is flat plenty of GPS L2. So did something with the new firmware cause the issue or something up with the new pro head… I would not expect it to be the pro, but I did catch it doing something strange at the end of a path turning around to come back the next path. It kept just going back and forth vs backing up turning going forward turning like it normally does. It finally got turned around but it was odd.
Anyway anyone else noticing any new path tracking issues lately?
\Without seeing some pics, my first guess is that it’s likely seeing ghosts and avoiding them. If that’s the case, the workaround is to turn off the ultrasonic sensors and switch to Gentle Touch. There are numerous reports of this behavior this year.
Watching it, it’s like when it turns around it’s just off path and just goes with it. A few times I noticed it, it’s like its running a 10" overlap which it’s not.
Idk same settings that worked without issue Saturday in the same area.
Some pictures.
Noticed the stripes they sorta tell a story too seems like it went down twice then back like it retraced it’s path. Strange behavior I’ve never seen it do. And like I mentioned it’s been mowing a lot already this year.
I have seen this and had this problem since last year. I am not aware of anything in particular in this release that would change it. It certainly has not been fixed yet.
Hi there, thanks for the detailed description — that’s really helpful.
Could you please submit a support ticket for this issue? This will allow our team to track the system logs and take a closer look to better understand what’s happening.
Turned off the ultra sonic sensors. It’s out mowing the back yard not a single missed stripe.
Why have they not figured out the sensors yet.
