If you’ve read any of my work before, you’ll know I’m a huge fan of the best robot mowers. It’s a corner of garden tech that just keeps evolving, and the latest models to hit the market have genuinely blown me away.
One standout collection is the Segway Navimow X3 Series – a new lineup I was lucky enough to see in action during a trip to France earlier this year. The range includes four models – the X315E, X330E, X350E and X390E – all designed with larger outdoor spaces in mind and packed with smart, user-friendly features.
Since my garden is on the larger side, I went for the X350E, which is designed for areas up to 5,000 square metres. It arrived a few weeks later, and I’ve had plenty of time to put it through its paces. Now, the verdict is finally in.
Segway Navimow X350E review: price and availability
The Segway Navimow X350E is currently priced at around £3,199 in the UK and $3,499 in the US. It’s available from several retailers, including Ron Smith & Co, Chaplins and Robotic Mowers Surrey.
The price means it’s definitely on the premium end, but for the features and performance, it feels like a solid investment if you’re serious about your lawn care.
Segway Navimow X350E review: unboxing and setup
After unboxing the mower, I decided to kick things off with the AI mapping feature to get my garden mapped out. I was genuinely impressed with how well it worked, and it picked up the clear edges of my garden surprisingly accurately. It wasn’t completely perfect, but I really appreciated the erase tool, which let me quickly correct any areas it misread.
Switching to manual mapping was also easy enough, and I used it for a couple of awkward corners where the AI mode struggled a bit. I watched closely during the first mow just to be safe, but after that, I felt completely confident leaving it to get on with the job by itself.
Segway Navimow X350E review: design and features
The X350E is completely wire-free, using Segway’s EFLS 3.0 (Exact Fusion Locating System) to operate. You can also choose between Quiet, Standard and Efficient mowing modes, depending on what suits your schedule and lawn.
The obstacle avoidance works through VisionFence 2.0 – a combination of AI-enhanced wide-angle cameras, 3D sensors, and Time-of-Flight detection – to identify up to 200 different types of obstacles. There’s also an LED headlight at the front for night mowing, and the dock allows you to add attachments, such as Segway’s strimming tool. Although, these are not yet available in the UK.

The X350E can cover up to 5,000 square metres (about 1.25 acres), making it a great fit for larger gardens. Thanks to its high-torque motors and grippy rear-wheel drive, it handles slopes up to 50% and copes well with uneven ground. The cutting height is adjustable between 20mm and 60mm, and the mulching blade leaves your lawn looking tidy whilst naturally fertilising the grass.
The mower runs on a 7.65Ah lithium-ion battery, providing you with around 180 minutes of runtime per charge, and it automatically returns to its base to recharge – which impressively only takes about 80 minutes. Its mowing speed is roughly 350 square metres per hour, which is solid for its size and power.
Control and connectivity are also highly advanced, and the X350E connects via Wi-Fi and Bluetooth, and includes optional 4G LTE for remote control when you’re away from home. The app lets you manage mowing zones, set schedules, check mower status, get alerts when it needs maintenance, and even notifies you when it’s time to replace the blades. There’s also a GPS tracker, which is great for peace of mind in case the mower ever gets moved or lifted.

On the mower itself, there’s a retro dot matrix screen showing real-time data and onboard controls – including a stop button and directional keys. You can also “drive” the mower manually via the app, or drop a pin to send it to a specific spot if it’s missed a patch.
Instead of traditional rain sensors, it taps into local weather data to pause mowing during rain, frost, excessive heat or even strong winds. It’s also IP66 waterproof, so it can easily be rinsed off if it gets messy.

Segway Navimow X350E review: performance
After a few weeks of use, I can confidently say this is my favourite mower I’ve tested to date. The AI mapping also exceeded expectations, and although I had to tweak a few things manually, the initial setup was smoother than most.
Obstacle avoidance in particular blew me away. I’ve had mowers in the past barrel straight through branches and sprinklers, but the X350E hasn’t hit a single thing. It feels really intuitive, and its 360-degree field of vision really makes a difference. Despite running often, there’s been very little wear or scratching, and it stays impressively clean. Grass hasn’t been clogging around the blades, which I’m hoping should help their longevity.
The build quality is also worth mentioning. Everything feels solid and premium, and genuinely reflects the higher price point. The Bluetooth connection was also very steady the entire time, and the mower runs incredibly quietly at just 54 dB – even quieter than the already whisper-quiet Husqvarna Automower 405X NERA.
If I had to nitpick, the lack of dual discs does mean the cutting results aren’t always as thorough as on models like the Husqvarna. If you mow frequently, it’s not a big issue, but if you try to avoid it as much as possible, it’s something to keep in mind.

Segway Navimow X350E review: verdict
The Segway Navimow X350E has quickly become my favourite robot mower to date. I’m extremely impressed with its AI mapping and obstacle avoidance, and once set up, it handled my garden with barely any input. Whilst the cutting system isn’t the most powerful I’ve tested, it still delivered great results with regular use, and the overall experience of using it – from the app controls to the way it navigates – has been a real joy. If you’re after a mower that feels genuinely intelligent and easy to live with, this is a standout choice.
Segway Navimow X350E review: alternatives to consider
If you’re unsure about the cutting results, I’d recommend checking out the Husqvarna Automower 405X NERA – it doesn’t have all the same bells and whistles, but the cutting quality is exceptional and it’s slightly more affordable.
If your garden isn’t quite as large, the X315E (for up to 1,500 square metres) or X330E (up to 3,000 square metres) from the same Navimow X3 Series are worth a look – they offer similar features at a lower price point.
