Robot mowers have come a long way in recent years, but some still fall into two categories: the ones that need perimeter wires, and the ones that get scared of tall grass. The UBHOME M10 falls into neither, and after testing it over the past few weeks, I’ve come away genuinely impressed. It’s smart, solid, and surprisingly bold in how it tackles the task of mowing, all without needing any backbreaking effort from you.

Setup and installation

Like most robotic mowers these days, setup is fairly simple. They have a nice unboxing guide, and you basically just plug the charging station in, then plug in the RTK satellite box. It’s important to place the RTK box somewhere with an unobstructed sky view, which gives it access to as many satellites as possible.

Unlike some other robotic mowers I’ve tried, there’s also a LoRa box that offers much better connectivity than WiFi, meaning the mower is basically always in communication with your network.

I was hoping to keep my RTK under the eave of the roof at my parents’ place where I set up the mower, but the app showed me that I was usually only getting around 13-14 satellites that way – a number that the mower apparently deemed insufficient. After moving the RTK post around 2 meters (6 feet) out from the wall, suddenly I had 21 satellites in connection and the app let me proceed.

RTK + Vision: No wire, no problem

The last step for setup was mapping the mowing area, which basically means driving the mower around using your phone as the remote control, showing it the area you want mowed. There’s no boundary wire – it just uses its 1-2 cm (around a half inch) precision from both satellite and AI vision sensors to keep your lawn in check. You can also set no-go zones, such as if you’ve got a planting bed or other area you don’t want getting a buzz cut.

It’s a major upgrade that the UBHOME M10 doesn’t need a perimeter wire like older robotic mowers. Instead, it uses that high-precision RTK GPS system fused with AI vision, giving it high accuracy while navigating the lawn. The mapping was a bit annoying, like driving the world’s most boring RC car around your lawn’s perimeter, but it sure beats hours with a trenching shovel and a spool of wire.

The last little trick employed by the M10 that I haven’t seen with other robotic mowers I’ve tested is the LoRa connectivity rather than relying purely on WiFi, so you don’t have to worry about your house’s wireless signal reaching every corner of your yard. In my case, the LoRa base station has been rock solid, even at the edges of my mowing area. The mower claims it can handle 1,000 square meters (0.25 acres) per day, and in my experience, it takes about two days to cover the full area, but that’s with me doing zero work, so who’s complaining? The mower just chews as much of the lawn as it can get in one charge, then heads back to its dock to recharge and pick up where it left off. Within two days, the half-acre is mowed. A week later, the process starts again.

Not just smart – brave, too

What surprised me most was how assertively this thing mows. Some robot mowers timidly bounce off tall grass like it’s an electric fence, afraid to enter what it deems to be a jungle. But the M10 plows forward with confidence. With a 230mm (9 inch) cutting disc of cute little razor blades, it chews through surprisingly dense Florida scrub grass areas without hesitation. It even handled a few overgrown patches on my lawn that hadn’t been trimmed in weeks.

It claims that it can tackle slopes up to 55% (around 29°) and handles uneven terrain well, but we don’t have anywhere close to that much incline, so I can’t speak to its mountain climbing abilities. I can say that one time it did get hung up on a particularly gnarly old tree stump that hadn’t quite been ground as flat as it should have been, but that’s a weird edge case. And when it happens, I’m glad the mower has a real handle. Many robot mowers are weirdly shaped and awkward to lift, but this one is easy to grab and reposition.

Smart controls and user-friendly design

Controlling the mower is simple with the companion app. You can check status, adjust mowing zones, and schedule tasks all from your phone. It’ll let you know when it plans to return to charge automatically when the battery gets low or if it starts raining, and then resume mowing once conditions improve.

It’s not the fastest mower around, but that’s kind of the point. You let it do its thing quietly and continuously, and it keeps your lawn looking good without you having to touch a push mower ever again.

Final thoughts

The UBHOME M10 hits a sweet spot in the robot mower market: it’s advanced enough to ditch the wires and smart enough to mow complex lawns, but without going overboard on features most people don’t need. It’s fast (for a small robot), fearless in tall grass, and simple to set up and maintain. For just over $1,000 on Amazon or $1,299 on the company’s site, it’s also modestly priced compared to the truly expensive robotic mowers on the market.

If you’re looking for a set-it-and-forget-it solution for keeping up to a half-acre of lawn tidy, this might be one of the most hands-off and satisfying ways to do it.
