Great lines & automation, but weak signal
Overall I recommend Mammotion's Luba! Pros: It makes really straight cross line cuts. The grass looks great! The automation with scheduling cuts is great as well. Cons: The Luba will sometimes drive just outside of the perimeter that I drew for it. This has caused it to go about a foot outside of the zone where it ran over a plastic drainage pipe and cut it up. It also drives into my wire fence daily as it doesn't detect it as an object until it runs into it twice. I wish it would self-learn that area instead of repeatedly beating up that area. It also has caused it to essentially get lost and it stayed there until I noticed and drove it back into the zone. The other major concern I had, was signal. Even though the antenna is away from any trees and the house, it doesn't have a great range. Sometimes the Luba is lost within 40 feet of it. This made it where I could only have it mow half of the back yard and half of one side yard. It still saves me time, but I wish I could have used it for a further range. I have about 7/10ths of an acre of land. Even though I programmed the Luba to follow the outside perimeter when traveling to new locations, it will take the shorted path causing a diagonal line through the grass.
