LUBA 2: turns tear up the lawn since the summer firmware, and what owners and Mammotion say to change

What owners report

• Around small excluded zones. A LUBA 2 owner updated to 1.30.29.26 and says the mower keeps tearing up the grass around two excluded zones of one metre by one metre. One of the two patches was already being reseeded when the second was ruined¹.
• In corners and in front of the charger. Another owner in the same thread says he gets this in all corners and in front of the charger². A third wrote that the mower was "killing my lawn too".
• A worn corner. A LUBA 2 owner posted a corner of lawn where, he says, bad software has worn the turf away over the last few months³. A few days later, in another thread, he wrote that remapping would only create new bare patches⁴.
• Zero-point turns. An owner in a thread started by an image-only post of 19 September says that over the last two or three firmware versions the zero-point turns have been chewing up the soil, even with multi-point turning on, and that turning the mower by hand does not do it⁵. The post names no model and shows ground torn up by a turn on a slope⁵.

These are separate owners across three threads. The posts do not give a LUBA 2 sub-model, and only one names a firmware version, 1.30.29.26.

What Mammotion says

• 21 September. A staff account asked the owner whether multi-point turning was switched on in the app. It suggested setting the severely worn areas as no-go zones and adjusting the mowing angle, to see whether that helps⁶. It also asked for a photo of the worn area and its place on the app map⁷.
• 22 September. To another owner who posted a torn patch, the same account wrote that the case was logged and shared with the team, and that a new firmware version would be released soon to improve operation⁸. It gave no version number and no date.
• 20 October. To the owner of the worn corner, the account suggested no-go zones again, and said mowing performance had been optimised in the latest firmware, 1.30.31.19. It asked how the mower behaves on it, and, if the turning is still not satisfactory, for a log and a video⁹.

Where owners stand

The owner of the worn corner answered that he would not test a new version for them when he has no way back to an older one¹⁰. Another owner asked for the spring 2025 firmware back¹¹. What can and cannot be rolled back is on Software rollback on Android: what's actually possible.

What is not known

Whether 1.30.31.19 stops the damage: none of the threads read here reports a result on it. Which LUBA 2 sub-models are affected, and whether the cause is the turning logic, wheel torque or something else. Mammotion's accounts have not named a cause.
