I’m currently in the middle of returning my Mammotion robotic mower, and Step 3 of their official return instructions raised a pretty big red flag for me:

"Important: Please completely cover any 'Class 9 Dangerous Goods' markings and battery-related labels on the outside of the package with blank labels. Otherwise, the package may be held by the carrier’s dangerous goods department."

Mammotion issued me a standard prepaid FedEx Ground return label. However, under U.S. DOT shipping rules, large lithium-ion batteries (like the ones powering these mowers) are Class 9 Dangerous Goods. Standard FedEx consumer drop-off locations won't accept a package displaying a Class 9 sticker unless it's accompanied by certified dangerous goods declaration paperwork and a matching hazmat shipping contract.

It seems like Mammotion is providing standard ground return labels to save on freight costs, then instructing customers to cover the hazard stickers so the package passes through standard FedEx drop-off without being flagged.

This leaves customers in an awkward spot:

• If you leave the Class 9 label visible: FedEx will reject it at the counter or freeze it at a sorting hub because the return barcode doesn't match hazmat electronic records.
• If you cover the label as instructed: You're covering up hazard markings on a standard non-hazmat label, and if the clerk asks "Does this contain lithium batteries?" at drop-off, answering truthfully will likely lead to rejection anyway.

Has anyone here shipped a mower back following these exact instructions? It seems pretty unethical for them to provide instructions like this when they know this isn't how it should be handled.

Looking at the update for Luba 2 1.30.29.20

It says it’ll improve the turns but also messes with the blade on/off logic

Those who have updated, what’s the lesser or 2 evils?

Having the tank turns, or the blades constantly turning off and off?

Holding off on the update for now, my grass is already ruined anyways.

After a season or more with yours, would you buy the exact same mower again, or switch brands? What's the one thing you wish you knew before buying?

I’ve had my Luba 3 AWD now for about five weeks. Despite the software challenges recently introduced my machine works and I generally like it. My challenges are more about how to successfully manage my mowing and here’s where I could use some guidance from more experienced users.

I have a larger yard. I mow about an acre of grass. When I got this unit in July scheduling the mowing was easy, it was dry and I could go many days in between and keep up. But as we’ve moved into August the rain has returned. Now my grass is growing at an incredible rate and the challenge has become keeping up. The day light hours are getting shorter and the grass is very wet in the morning. If we have a few days without rain the earliest I can get out is about 10:30. The latest I can cut is about 20:00. If it rains, the grass is much wetter and I have found it can’t get out until sometimes as late at 13:00.

I’ve tried cutting wet, it left really bad clumps, and given the way this machine cuts it’s not good at cleaning them up on subsequent days. I am currently cutting very short, I’m finding the shortest setting is not too short. I’m running blades at high speed, using the default speed and mowing path interval. I’ve considered speeding it up and increasing the interval to use less time to mow, but have not yet done that.

I’m wondering if I’m just asking too much of this machine and approach. Perhaps, given the operating environment, it just can’t be done without having more raw capacity than this machine can deliver.

I’m looking for any advice or tricks anyone has discovered to make this more manageable. Thanks in advance for any guidance.

Since updating the fw and app on my luba2 awd 5000H it is now taking 2x as long as previous to complete the same task.... Currently at 6 hours and it's not even half way done. When normally it's done by now...

Bonjour a tous,

Utilisateur français ici, je souhaiterai juste apporter un témoignage positif concernant mon luba 2X AWD3000, pré-commandé et utilisé depuis avril 2025.

Je n'ai aucun problème avec cette tondeuse ou le SAV mammotion, que j'ai sollicité plusieurs fois : deux pièces cassées par ma faute (le support de fixation des disques qui s'emboîtent dans le moteur ndlr + la protection en plastique orange sur le côté du robot)

A chaque fois, mammotion m'a envoyé les pièces gratuitement pour remplacement par mes soins, et pour la protection orange, le robot a effectué un voyage sans aucun soucis vers un de leur centre en Europe d'où il est revenu réparé, avec des disques de coupes et un jeu de lames neuves.

Le SAV via le chat a toujours été réactif, la tondeuse toujours opérationnelle.

Seul un firmware en début d'année à provoqué des bugs qui ont été réglé par un redémarrage du robot.

J'ai démonté mon antenne rtk à la mise à disposition gratuite du service inavi => ras, ça fonctionne super bien. Le robot s'est arrêté quelques fois la première semaine avec le message "vérifier que le rtk est bien positionné", mais problème réglé dans une mise à jour qui a suivi.

Mon terrain qui était un champ agricole ressemble aujourd'hui à un terrain de golf avec de belles lignes parallèles et un chouette mouton qui l'entretien à la perfection.

La dernière mise à jour à fait revenir le virage multipoint qui fonctionne parfaitement bien.

J'apprécie beaucoup tellement le produit et la marque que j'ai financé via kickstarter le spino E1 pro pour ma piscine, et j'ai hâte de voir les performances de la machine à la fin de l'année.

Sincèrement, merci Mammotion pour vos produits et le service de votre entreprise, je suis pleinement satisfait.

Vive Mammotion, et vive la France 😁

Great news! Since I was within the 30-day return window, I replaced my Luba 3 AWD 3000H with a Navimow X430, no more software headaches, no more zero turns, and no more unresponsive, uncaring customer service, good riddance!

Where did it go and where's your new found "transparency"?

Please... Fix your product. Bring back multi turn and not this half baked version!

Did a fun video. Hope you all enjoy!

Second post this evening and following on from my previous one.

After the pretty disastrous firmware update, I decided to slightly redraw the boundary of my lawn so it would avoid colliding with its timber house. I sent the machine out again, to see if things would improve, out of curiosity.

One of my cats was sat on the boundary of the lawn as the machine was moving forward, cutting the perimeter. She likes to sit in a particular spot and always the mower recognises her and goes around. Not tonight it didn't. Both myself and my wife watched in disbelief and horror as it continued on towards her. The mower didn't deviate at all from its path. Thank goodness she had her tail by her side and not straight out as it would have taken it off. The right back wheel grazed her as it went past causing my cat to freak out. I hit the emergency stop button as quickly as I could and then sent it back to its charging station.

I know some will say the area should be pet free etc etc but these things are meant to be able to run at night or on properties with huge gardens where it is not practical to be around all of the time. These things are meant to be wildlife friendly. You are meant to have absolute trust in these things. My cat is not small and should have easily been picked up by the sensors but my mower acted like she wasn't there. This has really freaked both of us out as we have 5 cats who come and go from the garden. I have been using this thing for months and it has always always recognised my cats and either stopped dead or gone around them.

Of note, after updating to the latest firmware, I powered down the machine for a few minutes to clear the cache. I checked and double checked all the app parameters just in case something had changed. Sensitivity is set as standard which it always has been. I mow on the slowest speed possible. I don't have any obstacle free zones set up.

My wife doesn't want me using this machine again. She is understandably really upset as this could have been a disaster. It was me that convinced her that it was a good idea to buy this thing and that it was absolutely safe. For the time being, I intend to go back to using my push mower.

I intend to speak to Mammotion in the morning and will update the post.

I stopped at 1.15.21.1 for Luba 2. Waiting to hear positive reports before further upgrades.

Is there a way to set straight lines on the map after I have mapped it out by walking the Luba? I just want the ability to make the lines straight so it doesn’t look like it’s dodging stones every few feet. Also would be nice to adjust the map myself without the need for the mower. If I am missing something please let me know!
For reference, I have the Spot On Nova dog collars, and they allow you to adjust the lines via the app after you walk the property. I’m hoping Mammotion has a similar feature.

​

I’m currently considering whether to keep the LUBA 3, and the recent Multi-point Turn changes are making me concerned about a possible hardware limitation.

My understanding is that one of the challenges with reversing while the cutting discs are running may be the requirement for reliable obstacle detection in the direction of travel. LUBA 3 does not have a conventional rear bumper or rear-facing camera, but it does have a 360° LiDAR system.

Could Mammotion clarify:

Can the LUBA 3’s 360° LiDAR fulfil the obstruction-sensing/safety requirements for rearward travel while the cutting discs remain running, including the requirements being introduced in EN 50636-2-107 Amendment 4?

If not, what is the limiting factor?

Is there insufficient LiDAR coverage in the near-field directly behind the mower?

Is the LiDAR technically capable of detecting the required obstacles, but not certified/validated as a functional safety sensor?

Is this currently only a software/algorithm limitation?

Or is additional rear-facing safety hardware fundamentally required?

And most importantly:

Is Mammotion working toward using the LUBA 3’s LiDAR for compliant rear obstacle detection so that future Multi-point Turns can reverse without repeatedly stopping and restarting the cutting discs?

I've been very happy with my Luba mini 1500, but that's because I haven't updated anything in ages. Ironically, because the update failed. I didn't bother trying again, then I read the horror stories.

I was planning to get another one for a second property, but that's not going to happen now. This latest update where nothing is fixed, none of the requested features are added, and not a single thing was available for anything other than the latest generation, has shown me that this company is not trustworthy.

I do still need a second mower, but I'm struggling to find a good option. I need 4wd, good ground clearance and the ability to handle rough, steep terrain. I don't care if it's rtk, lidar or whatever, as long as it works. It absolutely must be able to run in the rain.

The only real option I've seen is the Segway Navimow X420E. It looks like a great mower, but it's a lot more expensive than the Luba mini series. It's more of a competitor to the full size Luba. As far as I can tell, that's the only other option with 4 wheels though. Does anyone have a good candidate for a replacement for the Luba mini? I'd really like to take advantage of end of season sales that will be coming up shortly, so any suggestions would be appreciated.

Well after several months of my mower working perfectly, it has all gone wrong with the latest firmware update for my Yuka Mini 2 1000 LiDAR.

Twice I have had to hit the emergency stop button as it has ploughed in to its wooden house, wheels spinning as I watch It tear up the grass. It has never done this before.

I have also noticed it is much more aggressive backing up and three times it has gone in areas that are out of bounds.

I wish to God I never updated the firmware. I now join the unenviable group of Mammotion owners that are pissed off with their machines and this company.

Mammotion...sort it out.
