Damage to HEALTHY lawn by Luba 2's turning/trenching
Whenever someone posts a picture or video showing how the Luba is digging up their turf while turning, invariably someone will comment "ya, but your lawn isn't healthy; it's just a bunch of weeds on dirt" or somesuch.
My lawn is in very good and healthy condition. My front lawn in particular is the envy of the neighborhood -- truly as good as it gets for St Augustine. But the lawn perimeters and no-go area perimeters have been damaged by my Luba 2 3000H's turn-arounds. I just created a short video to show it:

For the 2.3 years I've owned my Luba, it's cut my front lawn twice each week -- with two separate tasks that mow parallel to the street on Tuesdays and then at 90 degrees to the street on Fridays. Also one of them cuts the perimeters without no-gos and the other cuts the no-go borders without the perimeters. This was working beautifully and caused minimal damage with its long, smooth MPTs for these 2.3 years.
With the firmware updates over the past 2 weeks making drastic "improvements" to the multi-point-turning, it's doing SEVERE damage to the perimeters and no-go boundaries. Pretty much ALL of the damage you see in this video was caused in just THREE mowings of my front yard since these MPT changes.
It's painfully obvious that if I continue to use my Luba 2 to cut my beautiful front lawn, that it will completely DESTROY these perimeters -- as it's done throughout my back yard already!
I also show in the video a portion of lawn that actually belongs to my nextdoor neighbor. He owns a strip of about 4 feet wide beside his driveway, ajoining my front yard. About 3 weeks ago, I saw him in his yard while he was watching my robot mow, and I offered that I could easily re-map my yard to include his little 4-foot-wide strip. He enthusiastically said "yes!" and so I made the change.
There are two small no-go areas in that little neighbor strip, around his tree trunk and a cut-down tree stump. These were no problem with the earlier firmware. But in the past two weeks, with just three more mows of this area, you can plainly see the damage it's causing around those two no-go borders: the grass is being TORN OUT by Luba's fierce MPTs. The neighbor came out to me again just after I filmed this and asked, sheepishly, if I'd mind NOT cutting his 5-foot piece. "Thanks but no thanks". I'll be re-re-mapping shortly to exclude it again. How embarrassing. :-/
Finally, I need to point out the extreme TIME difference in the cutting, old vs new firmware. It used to cut my front lawn in about 3 hours (including one return to charge). Yesterday it took over 8 hours and it didn't even get quite finished ... about 95% done before its 8PM no-mowing-period curfew kicked in and it returned to its dock. Well, the 8+ hours included FIVE "Robot is stuck", TWO "Out of area" and another "Complex terrain" pauses, and it took me some time before I could get out to continue it each time. (Which brings up yet another point: there's no push notification on my iPhone. I have to open the app and click on the bell icon to see these critical messages!)
I'll say once again: the latest firmware is an absolute DISASTER and the Luba 2 is effectively USELESS. Mammotion, please push another firmware "update" that lets us REVERT to a level from 2 weeks ago, before the Swedish toddler incident.
