Babysitting the Mammotion Luba 2

I have 3 Luba 2 AWD 10000H and 2 Luba 2 AWD 10000HX mowers. I programmed my areas and went on a two-week vacation. When I got home, not a single mower was in its charger. ALL of them were stuck in open areas. Turns out that if you're not there to constantly babysit, your lawns will not get mowed. Now I have 5 dead mowers and the grass is way too high everywhere. Nice job, Mammotion. Very impressive.
