When it works right......
When it works right, it is great. When it doesn't, it is terrible. Full disclosure, I have mature oak trees around the perimeter of my property. Knowing this, I installed the RTK on the roof of a single story home. Map drift terrible in early evening. Drifts from 2cm to 1.5m. Mowing the front yard (most open sky) really good. Mowing the one side yard just good(less open sky). Mowing the back....bad(least open sky but line of sight to RTK). Map shifts during mowing. Mower repeats passes thinking it is progressing but is not. I have tried 3 times and the mower has not completed the back yard although it thinks it did. All three times the mower could not get back to the dock due to map drift. It doesn't seem to adjust its location, once it is wrong, it stays wrong. I have to remote control it back to charge. Cut quality-pleased handles well Discharge-removed flapper, clogs reduced. I still wouldn't recommend wet cuts. Obstactle detection-Meh at best. Just using the bumper is like a demolition derby. Nothing subtle about it. The smart avoidance is not much better. It still smashes into things. This gets worse with map drift as the mower thinks it is somewhere else. Handling of terrain-excellent. If you do not have a completely wide open area, this is not for you as it is primariy GPS based. I want to love it because it is built well and capable. The navigation ability has a very small margin of error for successful use. No responses from customer service for any advice, tips, updates, etc. Will be trying the Mammotion Luba 3 with Lidar to see if it tracks better. Perhaps future iterations of this will perform more consistent. Lymow is not quite there yet. I don't hate it...but I can't love it. $3000 is a hefty price tag for limited results. Update 7/6/26. Lymow indicated they would send a new RTK in an attempt to resolve the issues, after a week no shipment or tracking. They offered to ship a new mower for a $600 deposit or ship mine back and wait for a new one. I don't believe a consumer should need to spend extra money to address a company's product not performing. There is not an updated model to receive, no indicated improvements to resolve the known hardware & software issues. They didn't mention any production or design improvements in a new mower. Just the hope that a new one happens to do better. That was a $3000 gamble I opted not to take. I finally chose demanding a full refund. I only see headaches going forward to continue down this rabbit hole. Rating now at 2 stars only because the mower does mow like a champ.....when it can mow where it is supposed to mow.
