Segway Navimow X3 Series: two-minute review
The Segway Navimow X3 Series robot lawn mowers are built specifically for sizeable lawns. And when I say sizeable, I mean sizeable – the range covers lawns from 0.5 acres / 1,500 square meters right up to a massive 2.5 acres / 10,000 square meters. To make them suitable for such vast spaces, these bots are designed to operate quickly, efficiently and accurately, with batteries capacious enough to allow for long mowing periods, without having to make the arduous journey back to the dock to recharge.
To see if this lawnbot could deliver on these promises, I sought out the largest yard I knew of. The lawn at my sister’s home, measures around 1,000 square meters / 0.25 acre (although Segway sent me the X350, which is designed for even larger areas still). The first thing I was struck by is the speed of the mower. It rolls along at quite the pace, navigating with confidence, even when traversing under trees.
The lawnbot itself is really quite large (and the same size as the other X3 Series models), but if you have a lawn big enough to need one, that’s not going to matter so much. It feels solid and high quality, with a friendly orange and grey color scheme and slightly retro-feeling dot-matrix screen to provide key information.
A big reason as to why the experience of using the Segway Navimow X3 Series is so enjoyable is down to the design of the companion app. It’s intuitive to use, walking you clearly through all the steps required to complete each process, and providing background information – rather than leaving you to figure things out by yourself. There are plenty of setting options to explore, and planning a schedule is straightforward.
In terms of performance, I had no issues. Throughout the test period, the bot behaved exactly as I’d hoped, mowing neatly and within boundaries, taking a logical route and never missing any spots. It also reliably avoided medium (soccer ball-sized) obstacles, although it did mow over a satsuma-sized ball (understandable, given it was sitting below camera height). Since this bot is two-wheel drive rather than four-wheel, it might struggle with especially rough terrain; but for the average yard, it will be absolutely fine.
Overall, a very strong recommendation for those looking for an efficient, fuss-free mower to take care of larger lawns. That’s the short version; read on for my full Segway Navimow X3 Series review.
Segway Navimow X3 review: price & availability
- List price: from $2,299 / £2,199
- Available: US, UK, AU
- Launched: Spring 2025
The Segway Navimow X3 Series was unveiled in spring 2025, and is available to buy in various countries including the US, UK and Australia. You can only purchase direct from Segway Navimow in the US, and normally these lawnbots aren’t stocked extensively on-line (you will not be including one to your Amazon Prime order). As an alternative, you may must verify the Segway Navimow website for distributors native to you.
In terms of pricing, brace your self: the Segway Navimow X3 Sequence would not come low-cost. The most affordable within the lineup prices $2,299 / £2,199 at record worth, and the priciest is $4,999 / £4,299. That is a big funding, and if you do not have a big yard – or a craving for ultra-speedy mowing – there are lots extra reasonably priced alternate options. Nonetheless, for these in want of large-scale mowing, the Navimow’s pricing is not too distant from what you’d pay elsewhere available on the market.
As an example you need one thing for a 1-acre / 3,000m² garden. The Mammotion LUBA 2 AWD 3000 prices $2,499 / £2,549 at record worth, and the Navimow X330 is $2,799 / £2,599. The LUBA 2 has barely extra superior options all spherical, together with all-wheel drive and two chopping decks, which makes it a better-value purchase at full worth. Nonetheless, each are wonderful, superior, high-quality lawnbots.
General, my expertise with the Navimow X3 collection was extraordinarily constructive, and it felt nicely constructed and thoughtfully designed, so I feel for big lawns it is definitely worth the funding.

Moving on to the lawnbot itself, and the brand has opted for a friendly look, with a dark gray and bright orange color scheme, and a dot matrix screen to provide key information in real time. On test I found this limited in its practical usefulness, although it is quite fun. There are physical buttons for Go, On/OK and Return to charge, plus a big emergency stop button. However, for the most part you’ll be controlling the bot via the companion app, which I’ll cover in detail in a separate App section under (there’s additionally help for voice management by way of Alexa or Google Residence, if you happen to favor).
The Navimow X350 is fairly massive, and for the occasions you may must manually maneuver it, Segway has added a giant deal with across the rear of the bot. Sadly, there is not any grip space on the entrance – so until you stick your hand within the cost slot, which fits towards an vital lesson I discovered as a toddler, you will must make do with crouching and dragging fairly than choosing it up.
It is pretty widespread for contemporary lawnbots to come back geared up with a digital camera for object identification and avoidance, however the X3 Sequence has not one, however three: one on the entrance and one on both facet, delivering a 300-degree discipline of view. Alongside one of many side-mounted cameras you will discover an Enlargement Bay part, the place you possibly can connect add-ons. There’s an edge trimmer attachment that already exists in a number of nations (I did not check this), and open API entry means if in case you have the abilities, you possibly can create your individual additions.
Additionally hidden someplace on the highest is a compartment for a tracker, do you have to want to add one for added safety causes (there’s additionally an out-of-bounds alarm, carry alerts and GPS monitoring to protect towards theft).
There are two principal wheels, plus two smaller wheels on the entrance. Since this bot is a two-wheel drive machine, it is not designed for very uneven terrain, though it may well nonetheless deal with slopes as much as 50%, and will likely be greater than as much as dealing with the typical yard (or soccer discipline).
Flip it over and you will find the chopping deck, which consists of six blades mounted on a rotating disc, which will be raised or lowered robotically by way of the app (it may well reduce at heights of 0.8-2.8in / 2-7cm). The entire thing is designed to keep away from the mechanism turning into clogged up with cuttings. Like most lawnbots, there is not any grass assortment right here – as an alternative you are meant to make use of it commonly sufficient that the tiny cuttings find yourself mulching again into the garden. The Navimow delivers a beneficiant chopping width of 9.3in / 23.7cm.
Additional components
The X3 Series is at least partially reliant on satellites for navigation, so in the box you also get an RTK receiver to enhance the accuracy of the satellite tv for pc data. You may want to search out a great place for this – ideally it wants to take a seat someplace excessive up, with a large, uninterrupted view of the sky. Since I used to be solely borrowing this machine, I simply caught it on the offered lawn-mount spike, and it labored remarkably nicely even on this sub-optimal place, as you will study within the Performance part. You should buy a secondary antenna to behave as backup if in case you have an particularly massive garden.
You are additionally supplied with a cost station, the place your lawnbot will return to juice up. This wants to take a seat on flat floor, with entry to an influence supply.
The lawnbot is IP66 rated, which implies it is proof against each water (all the pieces other than full submersion) and dirt. Even so, I are likely to assume a plastic storage roof is a good suggestion for a bit additional safety from the weather in the long run.
Features
Let’s look quickly at what’s going on under the hood. Like most modern lawnbots, the X3 Series doesn’t require boundary wires, but instead uses a combination of RTK satellite navigation, cameras and sensors to search out its manner round (this is extra on how lawnbots navigate, if you happen to’re ).
To make sure the bot at all times is aware of the place it’s, even when getting used on a palatial garden, Segway has launched numerous navigation upgrades. The RTK system has been improved and may apparently ship 40% higher statement, to maintain it shifting in potential blind spots corresponding to slender pathways or below rooftops.
Inside, two complementary wayfinding programs work collectively to assist the bot discover its manner about: VSLAM, which depends on recognizable visible cues; and VIO, which is nice for brand spanking new, featureless areas. All of that, added to the large discipline of view offered by the three onboard cameras, ought to imply this bot is an absolute professional on the subject of navigation.
Segway Navimow X3 review: performance
- Neat, thorough and very speedy mowing
- Confident, accurate navigation, even under trees
- Strong obstacle avoidance, although can’t spot very small items
Let’s start with setup, which I found fairly painless. There’s a bit of self-assembly required of the base station and RTK receiver, but if you hook up the app first then it walks you through the process quite clearly (there’s also a paper instruction booklet, if you prefer). The app also guides you through the mapping process.
My test lawn has unclear boundaries and tree coverage, so I opted to create a map manually, by remote-controlling around the perimeter of the area I wanted mowing and then editing the results in-app. I found the process straightforward. If you have a very simple lawn, you’d use AI Assist Mapping, where the bot will automatically map the area for you.
The first thing I was struck by when I started mowing was how speedy the Navimow proved. I was promised efficiency, and the Segway Navimow has delivered. The X3 rolls confidently along at an impressive pace compared to other bots I’ve tested.
I mostly used the Standard speed for my tests, but bumped it up to Efficient at one point but couldn’t really notice a difference. The app states that it’s 0.2m/s faster in this mode, which would be noticeable over time if you were mowing an especially large lawn.
I was also very impressed by navigation. My test lawn has a number of large trees, which I thought might cause the X3 to get lost – especially given the RTK receiver was just stuck in the ground, rather than elevated above the trees and buildings, as it really should be. However, all the test-runs were free of issues. The bot made its way around confidently, covering the full lawn in a logical pattern. It also accurately avoided a no-mow zone I’d set up in the center of the lawn, on a patch of ground that had recently been re-sown with grass seed. I guess whatever Segway Navimow has done to “improve the RTK performance by 40%” has worked.
I also ran a couple of specific object avoidance tests by placing large (a toddler’s ride-on car), medium (soccer ball) and small (a tangerine-sized ball) obstacles in the X3’s path. It had no issues spotting the car or football, duly skirting around each one, even when I kicked the football about to try to confuse it, but the smallest ball met a grizzly end beneath the X3’s blades.
We’ve yet to test a lawnbot at TechRadar that can spot small obstacles such as this, so it isn’t a particular failing on Segway Navimow’s part. However, it’s worth noting if you have, for example, a dog that likes to poo in your yard, and you don’t want to spend an afternoon cleaning it out of wheel crevices.
- Performance score: 4.5 out of 5
Segway Navimow X3 review: app
- Lots of useful explanations and info, with diagrams
- Plenty of fine-adjustment options
- Well laid out and easy to navigate
From the off, I was super-impressed with the Segway Navimow app. It provides plenty of information and clear explanations – often with diagrams – to walk you through everything from setup to how to map. Other lawnbot apps I’ve tested use opaque language and leave you to mostly figure things out for yourself, which can be especially confusing if it’s your first robot lawn mower.
Here, however, everything is logically laid out and easy to navigate. There are also plenty of options to fine-tune your mowing. There’s a straightforward schedule-maker, where you can select days, times and zones for cutting. You can also choose between three mowing speeds (Quiet, Standard and Efficient) and grass length (20-70mm, in increments of 5mm).
There’s a section for Map management, where you can split, add or remove sections, or add no-go zones (or, as Segway Navimow whimsically calls them, “BioLife Islands”). It will let you select where you want to start on the map, with the bot cleverly driving itself over to your chosen spot, and then the app will guide you to drive the new boundary line using remote control. I found this process straightforward and logical – again, not always a given.
Segway Navimow also offers a range of “Advanced” features, too. There’s an “Animal friendly” mode that will see the bot stop if it spots an animal and take a new route so as not to disturb it, rather than just skirting around it. You can also toggle on “Traction control” for particularly muddy or challenging terrain.

How I tested the Segway Navimow X3
I tested the X350 model of the Segway Navimow X3 Series. I used it for several weeks in the garden of my sister’s home. The test lawn measures around 1,000 square meters, and has unclear borders and several large trees. I set up the bot myself from scratch, following the instructions in the app, including constructing the charge station and RTK receiver. I mapped the lawn into different mowing zones and added no-mow areas. I assessed the lawnbot based on the neatness and speed of mowing, accuracy of navigation, and general ease of use. I also explored the different options in the app to see the extent to which I could fine-tune settings, and ran object avoidance tests using different-sized obstacles. I then compared all of my findings to other lawnbots I’ve used, while also weighing everything up against the price to gauge whether the bot offers good value for money.
