I tried to break the Luba 3 AWD robomower
When I reviewed the Luba 2 AWD 3000HX in September, I was seriously impressed. It’s quiet, very capable, kind of fun, and made me feel like a neighborhood hero while sending it from house to house mowing everyone’s yards. Since then, Mammotion sent me the US$2,799 Luba 3 AWD 3000HX for a review. Clearly, Mammotion wasn’t content with simply being “awesome.” Though the Luba 3 very much looks and feels like the Luba 2, it acts significantly smarter. The short version? I don’t see how you could go wrong with the Luba 3. The longer version: First of all, setup was an absolute breeze. Mammotion has done away with the need for an RTK entirely on the Luba 3, as long as there’s cell coverage in your area. While it really wasn’t that big of a deal to set up the RTK with the previous-gen Luba, it’s still a million times better not needing one more lawn ornament that you have to rely on for mower positioning. You simply plug in the base station to power, fire up the mower, and within a few minutes (after the updates, of course), you’re off to the races via NetRTK using Wi-Fi or 4G service. Should you not have cell or Wi-Fi coverage in your area, it can still use an old-fashioned RTK for that same centimeter-level mowing precision. My first real-world test was a fifth of an acre (9,257-sq-ft / 860-sq-m). The robomower knocked out 51% of the lawn in 2 hours and 21 minutes before returning to charge with 8% battery left. After it topped up, it headed back out and finished the entire job in 4 hours and 4 minutes with just that single recharge along the way. The results were literally perfect to the point of being boring. You can see the area the middle-weight Luba has completed in the background. It leaves little tufts of mulched grass in its wake, but it’s so fine that a slight breeze blows them away. JS @ New Atlas Very much like the previous-gen Luba, this thing just gets the job done and with virtually zero protest. In fact, after creating two large zones and marking off three no-go zones to protect the garden, the little robomower performed flawlessly. Not a single issue whatsoever – which honestly makes me feel like reviewing it based on that alone would seem inauthentic – so I asked the neighbor across the street if I could test it in his yard, because he has legit danger zones in his yard with irrigation swales, vertical drops, the whole nine yards. I was determined to put the Luba 3 in a position to fail by not marking out any of the hazardous areas and letting it just figure it out. It did eventually fail, but not in a spectacular fashion like I’d hoped. Instead, it was a very slight mistake that would have led to the mower turtling to its back, had I not caught it. It might look like a cool drop-in drift, but really, it fell into the ditch and slid sideways. To my surprise, it found its own way out with zero intervention!JS @ New Atlas When it would near potential danger – in this case, a vertical drop into a ditch deeper than the mower is tall – it would slow and move more cautiously before doing the best it could to mow along the obstacle that it recognized as a danger-zone. In turning around, a single front wheel slipped off the edge. Rather than simply reversing to save itself, it continued its zero-turn rotation, causing the rear tire to slide off the ledge as well, before I caught it and saved it from doom. A reasonable person would have marked that as a no-go zone. It also ended up in that same drainage ditch (albeit from a less dangerous, less flippy angle) when it did the same drop-a-wheel-during-a-zero-turn. It cruised around in the bottom for exactly 78 seconds, apparently contemplating its life choices, before it found an escape route and kept on truckin’. Impressive. Mammotion Luba 3 3000 AWD in a ditch, raw video It’s really difficult to figure out anything else that I don’t like about it, or that it doesn’t do well … well, except two things: the base station does not come with a roof. Should you want that, you’re going to have to shell out another $200, which is silly at this price point. And when manually mowing tall stuff, the bumper can be too sensitive for my bull-in-a-China-shop tastes. If it gets bumped too hard, it’ll cut power to the mow deck, forcing a ~5-second delay before I can start cutting again. That’s kind of annoying. I’ve also read a few others on Reddit mentioning connectivity issues, but I’ve yet to experience anything like that. The thing just works. Otherwise, having tested out several brands and models of robomowers, I have to say that Mammotion sets the bar very high in all aspects of its products. The app is the best of all brands I’ve tested thus far – it’s very intuitive, friendly, easy to understand, and with a wide range of options to fine-tune every lawn parameter. Or if you’re not into that, it’s also as simple as a “just go mow my yard” option. The app has it all. The app also does a great job of communicating with you; it will let you know when the mower goes to charge, when it resumes the task, when it pauses for whatever reason, the mower’s current location and progress … many things I realize I take for granted when testing other brands that don’t have those same features. This is what the app looks like. It’s quite polished compared to other mower apps that I’ve used. Definitely my favorite of all.JS @ New Atlas For example, when you’re creating a zone, and you make a mistake by driving off course, reversing the robomower will effectively undo
