Hi Chuck,

Thank you so much for taking the time to share your real-world, 2-season experience with the Luba 2.

First, I want to say I really appreciate the honest feedback. You make a completely fair point. Because this specific article was designed as a high-level “Buying Guide” to help beginners understand the different specs and navigation technologies, it didn’t dive deep enough into the physical, day-to-day realities of living with these machines. You are 100% right—what happens under the wheels and at the extreme edges is where the real test is.

Your observation about the inline wheels flattening 3.1″ Bluegrass is spot on. Because these AWD machines are quite heavy (often 40+ lbs), they act almost like a mini steamroller on cool-season grasses. By the time the grass tries to spring back up, the cutting deck has already passed over it. Setting the app to alternate the mowing angle (checkerboard pattern) is exactly the right workaround for the main yard, but as you mentioned, it doesn’t solve the perimeter passes.

Regarding the 4″-5″ uncut gap along walls and fences: this is truly the “dirty little secret” of the RTK robot mower industry. Because of safety regulations and physical bumper designs, the spinning blades are housed several inches inside the outer shell. No matter how accurate the GPS is, physical physics prevents a true zero-edge cut against a solid wall.

I completely agree with your outlook on the future. The shift toward 360° LiDAR (like we are seeing on the Luba 3) is helping machines navigate right up to the edge with much more confidence. And you are spot on about the hardware innovations—solving that last 4 inches of string trimming is the next great frontier. We are finally seeing brands experiment with offset cutting decks and built-in edge trimmers (like the models from Ecovacs, Dreame, and the Yuka) to address this exact headache.

Thanks again for holding us to a high standard, Chuck. Your insight is incredibly valuable to anyone reading this guide who is trying to figure out what owning a robot mower is actually like!

Best regards,
