Yeah, I had shot some video of it for an equal comparison, and have been too busy to edit it all together. I also wasn't sure what to say... the bottom is not clean, but it's not building up either. Running it wet seems to clean it off, but it also causes more grass to get stuck on the guards. I think you'll have a good experience if you coat it with this, and mow your yard with a gas mower, and then keep Luba running. I went out of town, and it rained, and luba did not run all weekend. We've had a lot of rain since then, and I have not been able to get luba to catch up. I also lost of day with the positioning error that everyone got. I was in the beta group, and installing the beta firmware got it running again, so I did not lose 2-3 days like many others. It's building up in the guards, but not on the deck like you see in the start of this video. I can still see the black deck through the thin layer of grass (before the coating it, the black did not show through on the main areas). Another option is getting an extra set of disks, I think they are $30 each from mammotion, then remove the guards. Also, run it every day so it's barely cutting anything. For me, it takes 3 days to mow the whole yard, so it's hard for luba to keep up.

@RobotMowerTricks awesome. I have a fairly small yard. Maybe 5 or 6 hours with my luba settings to cut. So I'll give this stuff a shot then! Before I do the first cut so it's easy to spray on 😄

Sounds good! I'd love to hear what you think of it over time.

@@RobotMowerTricks sure thing. I will test it out for a few weeks and come back to update how it goes for me

So, I have run the mower a few times now with the stuff applied, and it is much better. It is mostly cleared, with a few little patches stuck. But they come right off! I sprayed the mower disks as well, and so far, after four or five cuts, my blades are not seized up like they were previously! I'm glad I coated everything before the first cut so I didn't have to try and clean it out first. 😅

Glad it was helpful!

I think it would have some effect, you can always test it. I'd be interested in knowing what you find.

That was for Luba 1, i moved it to my Luba 2. They are no longer for sale. You can see the installation of it at the end of this video: th-cam.com/video/kYmlnqZfK6E/w-d-xo.html

Is your question where is the button to adjust the height, or you're using the setting, but it doesn't seem to be working?

@@RobotMowerTricks When I’m using “manual mowing” mode there doesn’t seem to be anywhere to select mowing height. Manual mowing is either “on” or “off”. I can’t select height of cut.

@@CH67guy1 you tap the gear icon in the top right. I'm on Luba 2, I assume it's the same on luba 1.

@@RobotMowerTricks I found the height adjustment for manual mowing! Upper right when you’re on the manual mowing screen. You touch the button and it brings up sliders for cutting height and maximum ground speed while manual mowing.

Line of sight makes no difference. The only way to answer your question is to watch the connections page. If the RTK and Luba are connected (I'll bet they are) then that question is answered. Will it increase accuracy? Possibly, the reason why is that accuracy is a result of coviewing satellites. So if RTk can see more satellites, there's a better chance (no guarantee) it will coview more satellites. But if Luba is driving between the houses and only seeing 10 satellites, and it's also coviewing ten satellites, most likely moving the rtk will not change that situation, since the rtk is already coviewing every satellite the Luba can see at that problem spot. I have a theory that vision gets confused when it drives between 2 houses that look similar (I was on a thread awhile back with a guy who has some seriously bizarre behavior and we had him video the mower, and screen record the connections page, and the bizarre behavior started when it switched to vision). So you might find that the satellites have nothing to do with this confusion, Luba might be switching to vision, and the vision is confused. Let me know if that makes sense and/or you have any other questions. There are some mammotion articles on their website about how to understand the connections page. The best one is under luba 1

@@RobotMowerTricks Thank you SO much for taking the time for such a learned response!! Yeah, likely to yr pt it's the vision element that is getting it confused (which is odd as the homes have very different profiles, etc. I have to move my RTK anyway and remap (as my 1st spot wasn't ideal). I've also learned (and mention on these threads) oddly the slowest speed I can stand for mapping tends to create the best results on edge integrity, etc.

Yes going slow is good for mapping accuracy, and I also stand back if I think that the satellite count is low in a certain area. i don't want to my body to be blocking the satellites in addition to the house/tree/etc. I hope moving the RTK works for you! It's never a bad thing to move it higher/more open.

@@RobotMowerTricks Oh, that is SUCH a BRILLIANT tip (staying back as to not block the satellites on the mower). I've been standing right over it. THANKS!!.

For Luba 2, the website says 5km (that's a little over 3 miles). There is talk that a sim card might be required to get that range, but I'm not aware of anything official saying how far you can go without a sim card. So I would take them at their word: it says 5km in one place and it says sim is optional in another place, and we should complain if it doesn't work. Currently I don't know how to give Luba multiple wifi networks/passwords, so it won't have any internet that far away unless you set up a router at the second location with the same credentials as your home router.

I don't have any IOS devices, but I've used my old phone and it worked fine. All the maps are stored on Luba, so if it isn't loading the map right, it's an issue with it fetching the map from your mower. Maybe an IOS glitch, maybe a network glitch, maybe Luba just needs to be turned off, pull the key, sit for 5 minutes, turn it back on, let it sit for 5 minutes again. The app is buggy, I do have to close it out of memory fairly often, but the mower itself has finally been solid since the last update. I have not had to do a remote rescue since then. Upload a lot of logs for every problem you have, and they might just be fixed in the next update.

Check out my follow up video that I made just for that question th-cam.com/video/dXznh5VWzf8/w-d-xo.html

Glad I could help!

Thank you!

You're welcome, I hope it works for you! If you could help me out with a vote, I'd really appreciate it. No personal info, just tap vote then tap it again after it says "success". I'm trying to get enough votes so mammotion can't ignore honest reviewers. cont.st/uZnrsv_nThtij?g=1

Wonderful to know I'm not crazy! Thanks for sharing! Let me know if your plan works. it's possible you will need to delete the channel and redo it and retest it to make it work. But I have no idea, we're sort of in "glitch" land, but I know that once it starts working, it's never stopped working. But yeah, if you could come back and say if you had to delete the channel or not that might helps others int eh same boat. I agree, they really need to let you make a channel on top of the other one and show it that way on the map!

@@RobotMowerTricks Alas, my testing of this was unsuccessful. But I have a weird topology. Your trick may hopefully work for others. I deleted the area close to the charger. The channel (following my concrete pathway) showed up again. And curiously, I can't find any way to DELETE a channel! Only by defining a NEW channel between the SAME areas. (And another wish I have on my list is to ALLOW multiple channels between areas, so we'd really need a DELETE CHANNEL capability. But I diverge.) I ran the Luba out to mow the connected area, aborted the mowing, and told her to recharge. She followed the channel/pathway perfectly both ways. I created two more channels for two more areas, along the SAME pathway back to the charger, and again sent Luba to mow and return on each of these. She behaved perfectly. But once I recreated the area closest to the charger, which is "over top of" these channels, the behavior changed. And Luba is now somewhat confused upon exiting the dock, now that I have three channels converging there. She eventually figures out the right way to go, but unfortunately doesn't follow the pathway to any of the three areas. Now the curious thing is that she DOES follow the very first channel that I created back to the charger. But not for the others. I'm thinking that I'm totally bamboozling the software by having three channels "on top" of one another, and then an area on top of all three. Anyway, it was a fun exercise, but didn't work for ME. Your mileage may vary.

@@HangarQueen so you'll need to delete the channels anyway to stop the odd driving. (you do that by tapping map, edit, finding the area and tapping the down arrow and you'll see channels and no go zones in that area. You can delete them individually.) I suspect that if you delete all the channels and retest it'll work.

@@RobotMowerTricks Dang, I never noticed that sneaky "down arrow" under the areas in map editing ... which as you say allows channel and no-go deletions. Thanks for the pointer. (And now I need to update my "Issues and Wishes" document, as it's currently suggesting that this capability is needed.) I'll see if I can find some time to get out there to delete and re-test later today. Thanks again.

You're welcome! Let me know!

The drop down arrow. I can't leave pics in comments, but that's always the key people are missing. Go to edit, find the area that has the no-go zone, and tap the down arrow to see the channels and no-go zones in that area.

@@RobotMowerTricksgreat advice! An upgrade just came - let’s hope they introduce a randomised path to task area from charger. It’s the biggest issue.

@@ipodman1910 I'm in the beta group, and so far they only have random cutting angle as a feature, and it has issues. I'm not sure how many people want their yard cut at a random angle. Random driving paths would be much better.

@@RobotMowerTricks exactly!

I'm glad you found this useful enough to be wiling to try it! ...You never know how people will respond when you put stuff on the internet...

You cannot map channels until you map areas. I thought about making a beginners guide to mapping, but I felt like this is for advanced users who already have maps and understand the weird things Luba is doing. The beginner's guide is that you need to pick how many areas you divide your lawn into, then map the furthest area first, draw a channel, and let Luba use it both ways. Repeat in the order furthest-nearest, getting closer to the charger each time.

@@RobotMowerTricks Thanks for this. My Luba is due to arrive tomorrow and I will keep track of how I set things up. One of my channels will overlap with another but the end points are different so I don't foresee a problem on that front. I'm terribly excited about not having to mow the lawn regularly - fingers cross it all works well!

@@charleswheatcroft Enjoy! Overlapping channels should not be an issue, I've seen screenshots of that. It might be best to map zones as large as possible (but also 1 foot away from rocks/walls and let luba put down straight lines for you to use as a guide when you remap once you see what you'd like to change. Also you can us FPV to watch luba drive perimeter laps to see if it's going to hit something. You can pause it, take note of the percent complete, then end the task, edit map, and start another task using the "start percent" option to jump ahead to where the problem/edit is.

Yes, very recently. Are you on the facebook group "Mammotion Luba Issues & Solutions"? I'm not sure if this link will work but it's my post on May 21, 8:11pm facebook.com/groups/1673804186375888/posts/1887468745009430/ Here's what I said in my post: Solution: This week I've been having an issue where the cutting height slider is for standard, but I have the high model. Even killing the app doesn't fix it. But I've found it only does this when creating the task from the device selection screen. If you tap "enter map" then tap "mow" it works for me every time. You can even go back to the task list and they are corrected as well. Luba 2 5000H, Android. (PS you can just load the map, and back out to your task list if you're planning on editing or copying an existing task) One comment said restarting Luba fixed it, I suspect that's true, but it might come back at any time. I think the app has a default for the standard height model and it needs to be overridden by the high version.

Mammotion Potter also said, "Sorry for that. We're looking into and will locate the causes to fix it soon."

I'm glad I could help!

Thanks!

Nope! Just put Luba on the charger manually, and go to settings, then relocate charging station. It will be greyed out of its not charging, it needs to be charging. You can do it again when the GPS quality is better too, anytime it's charging. If you relocate the rtk, then you need to remap. But every time you remap, you'll get better at it.

Only when trying to tank turn. When driving straight the omni wheels let it down, pun intended. But the back tires are pretty solid until it starts riding sideways. But that's more from the steepness than the treads, I think.

Oh yeah, but it gets it done. When it rides sideways it's quite impressive. Certainty the only mower I know of that can do a bumpy steep incline like this!

How about HQ 535awd and 435awd? They do insane better than this…

@@Dr.banansko Are they wire-free?

@@RobotMowerTricksno but that doesn’t make any difference in how it can handle slopes

@@Dr.banansko but it means they are not to be compared to each other.

Yeahhhh... Some people were having that problem after the update last week. I didn't have that problem until I started recording 😅 But I think it's fixed now

Transition zone of grass types, eastern shore of the USA.

It's possible because satellites communicate with radio waves, and radio waves go through walls. They are very far away, so the waves are weak, and so obstacles can easily block them. But one layer of shingles and one layer of plywood and some insulation is not enough to block them.

Only works with the power brick since it's a different connection. If I've helped, I'd really appreciate a vote, it only takes 2 taps: cont.st/uZnrsv_nThtij?g=1

Yup, that is true, but when it makes it to the bottom of each run, it will slip the entire time it is turning around, and fall out of the area. It won't hit the water, but it will lock the Luba as soon as it's out of the cutting area. You can see this happening from 2:23-2:27. On the map you can watch it sliding backwards out of the area. It managed to catch itself right before triggering the "out of area" error and locking the wheels.

Glad you got it to work!

Once the sun is about halfway set, Luba 2 is functionally a Luba 1.

If my videos and comments have been a help, I'd really appreciate a vote, it only takes 2 taps: cont.st/uZnrsv_nThtij?g=1

Not at all, I do not have a sim card.

Along the ditch bank, not in an out. I just made a new video showing it successfully mowing the ditch, and it is only one way. th-cam.com/video/c6Qt7u4TxvM/w-d-xo.htmlsi=s0O-a89UNmRRHf6k

Glad I could help! I remapped and it doesn't get stuck at all now.

I have a new (short) video of my ditch bank: th-cam.com/video/c6Qt7u4TxvM/w-d-xo.html

Yes, this video was in February. It was mostly weeds that needed to be cut.

Glad I could help! It's worth trying a few places, but you almost need to leave it for 2 weeks as the satellites move.

The reviews on those say they don't work well.

@@RobotMowerTricks I use 3d printed covers over each of those spinning disks to cover the blade screws on my Luba 5000... YES... it actually does work really well. I also replaced the screws for standard Phillips screws... I highly recommend the cover.

@@covertpuppytwo3857 mine came with Phillips. That's great yours are working

If you have a clean lawn, that is a good option, but you need to keep enough of it to seal the rubber. But I have falling sticks, pine cones, and a few concrete spots

I discuss the heat in my orginal video, but the answer is, it's up to you. Other's with a traditional attic are doing it and no one has reported a probem, but they might keep quiet lol idk. th-cam.com/video/kYmlnqZfK6E/w-d-xo.html The Luba 2 is a different RTK, but both will work in the attic. I tested my Luba 1 in the yard and in the attic and found it better in the attic. So on Luba 2, I put it up there, it's all in the video I linked to. Using the L bracket/mount right on the peak of your roof is THE BEST way to mount it, but without a solar panel, that's not an option for me.

I have no sim card, so no, a sim card does not create this ability, the camera does. The current distance the LoRa signal will go is unknown but no one in the (facebook/reddit) groups I'm in has reported a connection problem between the RTK and the Luba. It's just not an issue. The issue is always co-viewing satellites. They both need to see a good bit of the same sky.

When I set up Luba 1 last year (then returned it when Luba 2 was announced) I put it up as high as I could reach (around 8') and it was spotty. So I got a bucket and moved it up another foot. Then the actual RTK was at the top of the wood I put the pipe clamps on in this video. Then I had no issues. So height helps, but it was still a few feet from the top of the roof and working fine. Going back to Luba 2, after this video, I did end up sliding the RTK down about 6" from the rafter ridge. It seemed to pick up an extra 2 satellites. I wasn't having problems, but I needed to mess with it for some reason I can't remember.

I've never heard of that before. It seems like people have very different experiences. You can verify this buy opening the app several times at night and check the connections and see the RTK status.

Thanks for the comment. I had heard of users having problems when they use water while upside down, but I've never heard that the guards seal the rubber. I'll have to look into that

@@RobotMowerTricks maybe I chose wrong words. Guards press rubber down to seal. Otherwise rubber will lift up and make a gap. Also, I mow without guards for more than half year without problem

@@0ssaa Did you totally remove the guards so they are no longer pushing on the rubber to seal it? Or keep the plastic plate and drill out the rivets to remove the metal part?

@@RobotMowerTricksI surmise the metal part is to protect “fingers” of anyone who might try to lift the Luba while it is traversing a yard. The metal parts certainly shield the outermost reach of the blades. I have a Luba 2 AWD 10000H mowing the full 2.5 acres so I have certainly experienced the little idiosyncrasies of the Luba 2. I’d say to anyone considering buying a Luba 2 to just pull the trigger and buy it. It’s a game changer if you’re someone like me who loathes mowing grass. I’m considering buying a second Luba 2 for a more distant part of my property where I mow around farm buildings that are outside the confines of the 2.5 acres that my house sits on.
