Two things that make this mower less than it could be. The first one is huge. 

1.  Apparently there is no, almost incomprehensibly, feedback loop between the mower section and the robot other than the robot telling the mower to run at a particular speed. Whether it does it or not, the mower has no clue.  So if the mower gets into higher grass, or a bump, it can turn off, because the circuitry is saying it's too much for the mower.  But it doesn't tell the robot that, so the robot continues to merrily act as if the blades are turning, when they are not, **leaving a big patch of grass unmowed**.  Maybe not a problem in a suburban lawn environment, but that's not why I bought a tracked mower for my rural and large property. The robot should clearly stop if the mower has stopped for any reason, and wait till it restarts, then proceed. It seems blindingly obvious. 
2. No way to control the mower remotely via Wi-Fi or cell. So if it gets stuck, and a lot of times it's just a matter of jogging it a little bit with the manual control via the Bluetooth, it can get unstuck. It would sure be nice be able to do that remotely, and I understand that there may be some safety issues with that. Perhaps there's some sort of disclaimer a user could digitally sign before something like that is enabled. The way it is now, if it gets stuck, and you're not right there, you're out of luck. And if you happen to be at work or something like that, it may just sit there and run out of power. Bit of a failure there.
