Although I agree with most ch of the OPs comments, with some adjustments I keep getting better and better looking lawn. For its many flaws I am becoming happier with it. It does share flaws common with many robot mowers, like the guards.
The gap around the no go zones is really not good. I am experimenting with templates to reduce this. Largely this is my biggest complaint. I have a robot to save me time, although it does this it is adding more of my most hated activity, trimming. Until it gets closer I can’t see their trimmer being much benefit.
Routes are bad, I expect some across the yard travel, but currently its efficiency is poor at best.
My tips taken from others…
Turn off vision when possible.
Certain things are better without no go zones, think things that clearly are bump avoidable.
Mow often - 1/2 inch cuttings work well
I hate this - 8in overlap (largest) really makes a huge difference.
Don’t mow wet and especially dew grass
Keep in mind that this is relatively new tech and users are early adopters. Vacuums took a long time to get where they are at and have confined spaces with relatively low damage possibilities.
I also own a Luba, while it has better ability to go under trees, maintain very tight boundaries, and much more efficient routes it lacks in other areas. Like size capabilities, worse cut, you must draw everything, and lack of adjustments. It also just goes out of bounds for seemingly no reason - mine was ran over for this reason (also due to no alert). You can’t move remotely at all, must be within 15ft of mower. It is one of the more proven units out there for mowing. It also lacks any attachments of course.
It shares the cross yard cuts, bad vision, worse obstacle avoidance, poor alerting.
Until Yarbo can improve it’s no go mowing it will share responsibility with Luba. Luba being the trimmer.
I firmly believe that Yarbo will continue to improve as Luba did, difference is is Yarbo is hugely more capable.
I would like to thank the OP. More attention and prompter resolution/improvements are needed. I see these same comments throughout the forum.
