Excellent point. I'd like to revisit this video at some point to show that better. You CAN see a bit of before and after in the small area where the Yarbo is overlapping with its own previous row, though. And at the very end, you can HEAR it cutting, but it could/should be much more clearly depicted.
Optimizing the mower deck and blade design has decades of perfection. Why these high school robotic companies think they can just change what we have learned is naive on their part. They don't know what they don't know. (1) The cutting blade should extend beyond the wheel width so as to best cut grass before it is run over twice by the rear wheels. Once the grass is bent over and packed down, it is very difficult to cut. (2) The mower blade and deck design produce a vacuum that lifts the grass so that it is standing up to be cut. Razor blades do not do that. If you have pets or children playing on your lawn, those spots may never get cut. These are 2 very simple flaws in the robotic lawnmowers that can easily be improved upon. The weak link is battery power. Yarbo has a leg up on the competition in that department. They can easily add a 3rd cutting disk and widen the cutting area. Spinning a fan may help provide lift. Maybe a disk plate redesign.
Pro version has 3 cutting discs. Trying to convince them to resurrect that program for golf courses at the moment (it's been temporarily put on hold to make sure residential mowers promised are actually delivered). They've stated that power consumption is the reason vacuuming grass up before cutting isn't feasible, but it's possible that 'brushing' it up (similar to a vacuum cleaner beater bar or leaf sweeper) is doable... A mechanical engineering contact of mine is looking into options for redesigning the cutting disc to create proper air flow though, so stay tuned...
Oooh, good question. I'm willing to accept their premise, just based on plausibility, that they've come up with something that can mow grass better as a dedicated mower than Yarbo, BUT, they've got a LOT to prove, in terms of whether the company can actually address the mass market they're targeting. Would love to see a lymow in person, but at the same time, there's a difference between good idea and good execution.... Maybe they'll be at Equip Expo this year and we can ask them the hard questions in person :)
@@MichiganRobots True. I'd throw Yarbo into the camp of good idea, not good execution. They seem to have great marketing, but they've been making promises that haven't come to fruition for too long. Hopefully Yarbo can improve their execution going forward. Hard to make any comments about Lymow at this point since they don't even have prototypes out in the wild yet, but I am hoping they can execute well.
@@BoxleyAcres imho promises unfulfilled is the definition of BAD marketing.... Yarbo is strong on the mechanical design and manufacturing aspects, decidedly WEAK on electrical and software fronts. I could make multiple videos about features that were presented as "ready" when in fact I'm not sure they'd even started working on them... It's really tricky to present both sides of the coin, especially if I try to do it in a single video... More critical review videos are sure to follow, stay tuned :)
@danielcomptonnz i haven't done specific testing to compare, but anecdotally, no, it doesn't. I notice ruts and matted down grass much more with Luba, especially on the paths between work areas and back to charging station. I didn't really test them side by side over a period of time to say for sure. The Luba may have just been more noticeable because I've had it for longer. The weight on the front castor wheels is only like 6lbs with Yarbo, but like 11.5lbs with Luba, so less matting there, for sure. The bulk of the weight is spread out over the treads. Good idea for future test/video to test matting though.
My Luba mowers were the best at the time. And I'll still keep them as backups, but my Yarbo is here and it will be taking over in the spring. In the meantime, it's waiting for the first snow to start doing my driveway. If you have the money, go with Yarbo. But Mammotion would be my second pick and Yarbo would be my number one. Plus, Mammotion still refuses to fix the donut hole issue in front of the charger.
This is why I'm very interested in what the oasa r1 is going to provide with it's reel blades once they get started next spring
Send you a Garbo for free, I’m sure the wide flat track on the Garbo does not lay any brass down . Please.
I see what you mean about the Yarbo black chassis pointing out the high spots that the Luba missed, but I can't tell that the Yarbo actually cut them.

Have you looked at Lymow's mower? It has traditional blades and creates suction to address these issues. Curious what you think of it.

@@MichiganRobots Good point. Looking forward to future videos.
Does the Yarbo squash the grass down more because it is heavier than the Luba?

@CollinLutz-p9e ditto on donuts in front of charger, but overall I love my Luba too!
