Segway Navimow i208 LiDAR review: the robot mower for complex gardens

Oliver Grant • October 3, 2026 10:21

Narrow passages, dense shrubbery, twisting corners… the Segway Navimow i208 LiDAR claims it can handle gardens that entry-level robot mowers fear. We put it through its paces for two months on a challenging plot to find out whether its €1,199 price tag is justified.

Choosing a robot mower in 2026 is no easy task. In barely three years, both the number of brands in the sector and the number of available models have multiplied. At the same time, most products have replaced aerials and perimeter wires that need laying with the promise of wire-free mowing.

Several navigation technologies are competing in this crowded market: RTK, AI vision, LiDAR and wide-angle cameras, often at very similar prices. As a result, working out which system best meets your needs can be difficult.

Take a practical example. In 2026, a wire-free robot mower such as the Mova ViAX 250 can be found for roughly €600. At this price, however, it has no LiDAR navigation and is limited to a maximum area of 250 m².

At the other end of the scale, the Roborock RockNeo Q105 claims to cover areas of up to 500 m². It still does without LiDAR, but this time includes an aerial. Then there are manufacturers with exceptionally broad ranges, including Mova and, above all, Segway Navimow, which unveiled around twenty new models last spring.

Into this confusion arrives the Navimow i208 LiDAR. With its three sensors, this wire-free robot is aimed not at small, straightforward lawns but at complex gardens full of tight routes, flowerbeds and dense vegetation. It can manage areas of up to 800 m² and launched at €1,199. If that sounds like your garden, this review is for you.

What we liked

Quick, intuitive setup

For Segway, 2026 represents a turning point. None of the new robot mowers the brand introduced last spring requires a wire to be buried around the lawn or an unsightly aerial placed in the middle of the garden.

Like the other models in its range, the i208 LiDAR only needs its charging station, positioned in a spot that receives your home Wi-Fi signal, and most of the setup is complete. Once it is connected, alongside Bluetooth pairing, the robot is ready to map its new surroundings.

There are two ways to do this. The first, and most conventional, puts you in control. Using a virtual joystick on your smartphone, you steer the robot around the edges to define the garden boundary. It requires a little dexterity, particularly on a plot with plenty of corners.

The second option is automatic mapping, a feature becoming increasingly common on recent LiDAR-equipped models. Here, the Navimow i208 LiDAR explores the lawn and creates its own map. In practice, this option is only worth considering for simple square or rectangular gardens with few obstacles - effectively the opposite of the type of plot for which it appears designed.

Once the map has been created, you can view it in 3D and add no-go areas, boundaries and transit points. This is an important stage, as it largely determines how well the robot will navigate afterwards. Setting up the robot and mapping our initial 250 m² area took just 45 minutes in total.

Ultra-precise navigation and a comprehensive app

This is where the Navimow i208 LiDAR truly excels. To find its way without an aerial, the robot relies on three sensors: a LiDAR unit that scans its surroundings even in low light, a wide-angle camera for obstacle detection, and satellite positioning to establish its location.

The results matched the demanding course we set for it. Our test area featured numerous planted beds, trees with large exposed roots, stone-bordered flowerbeds, garden furniture and small winding corners. The Navimow i208 LiDAR never fell into any of these traps.

Throughout our two-month test, we never had to rescue it manually from an awkward position. Better still, we placed obstacles in its path unpredictably to push it to its limits, and it avoided them without difficulty.

The Navimow app is fairly comprehensive without ever becoming cluttered. Cutting height can be set independently for each zone, from 20 to 70 mm, while the mowing direction can be selected to avoid leaving marks on the lawn. Little else is missing: you can schedule operating times, lock the buttons to protect children, and use a rain sensor to stop it working during a storm.

Segway has even included the option to mow a heart or a letter into the grass. If you are artistically inclined, or planning an original marriage proposal, it may come in handy.

Clean cutting and careful build quality

Turn it over like a turtle and the Navimow i208 LiDAR reveals a six-blade cutting deck that mows a width of around 22 cm. This is not the widest on the market - some models reach 26 cm - but the results are highly satisfying.

During a mowing session, the robot works in neatly parallel stripes. It remains methodical from start to finish. Where some mowers appear to wander about randomly, rather like headless chickens, this one never seems lost. The cut is clean and, above all, extremely even.

Almost no stray blade or clump of grass survives its passage. Almost, because another benefit of its excellent navigation is that it carefully goes around the small flowers occasionally found in its path, leaving them intact. There is no need to mark daisies as no-go zones either.

What we liked less

Edges: the perennial problem

Like robot vacuum cleaners, which are largely unable to remove dust from small corners, robot mowers face a similar limitation: cutting close to edges. It is currently the key battleground in our gardens, and every manufacturer is trying to find a solution.

For example, Mova offers a manual mowing mode on the ViAX 250, allowing you to guide the robot yourself to finish particular areas. On its i208 LiDAR, Navimow instead relies on its EdgeSense technology, which is enabled by default.

In practical terms, during a standard mowing run, the robot always begins by following the boundary before filling in the middle, getting as close as possible and leaving only around 5 cm uncut. Along a gravel path or a perfectly level patio, it works well, with the mower almost overlapping the edge.

Against a wall or dense vegetation, however, there is no miracle. Since its cutting deck does not extend sideways, it leaves around 10 to 15 cm of uncut grass. Anyone particularly particular about their lawn will still need to finish these sections with hand shears.

Wheels can slip, and charging is slightly slow

The robot uses two driven rear wheels and two swivelling front wheels. This conventional arrangement works brilliantly on dry ground. It moves easily and can negotiate tight turns. It also climbs slopes of up to 45%, or around 24 degrees, without complaint.

That said, we found that its wheels can start slipping in places as soon as the ground becomes soft or waterlogged after rain. This is not a major issue: while it can navigate a complex garden, do not expect it to perform like an all-terrain machine on very steep, muddy areas.

Its battery life is fairly impressive. With its 5.1 Ah battery, it can cover between 215 and 240 m² per session. The more frustrating point is its charging time.

It needs a good two hours before it can get back to work. Taken together and applied to its maximum 800 m² coverage area, expect roughly four mowing and charging cycles, or a good twelve hours spread over one or two days.

A few other minor shortcomings

A handful of small details prevent the Navimow i208 LiDAR from achieving a flawless result. First, mowing customisation is rather limited for a robot at this price. You cannot choose the order in which it handles different zones, how many passes it makes along the edges, or the speed at which its blades rotate. In short, every mowing session is treated the same way.

Then there is the 4G module. Its purpose is to let you retain control of the robot even when it is outside Wi-Fi range. If you go on holiday, for instance, you can start a mowing session or receive an alert if somebody attempts to take it. Its GPS chip also makes it possible to locate it. Unfortunately, this convenience is only included for the first year. After that, it costs €30 per year to keep using it.

Finally, although the robot itself feels robust, the same cannot be said for its charging base. Its orange accents add a welcome touch of colour, but it is made from very thin plastic - the kind more commonly found on less expensive models. If you also want a garage to protect your robot from rain, you will need to add another €149. These extras can quickly raise the overall cost.

Our verdict on the Segway Navimow i208 LiDAR

Robot mower prices may be falling, but it still pays to choose carefully. For a flat, square or rectangular lawn of no more than 500 m², affordable models under €1,000 may be sufficient. That is true of the Roborock RockNeo Q105 and the Mova ViAX 250, both of which we tested recently.

However, once a garden becomes more complicated, with planted beds, vegetation, a patio, gravel paths or narrow passages, it is a different matter. This is what we call a complex garden, and a LiDAR navigation robot becomes essential for this type of plot.

That is exactly what the Navimow i208 LiDAR offers. Its trio of sensors delivers ultra-precise navigation and obstacle recognition. Installation is also quick, with no aerial to install, the cut is tidy, and the app is reasonably comprehensive.

It is not perfect, though. Its edge cutting still has room for improvement, while its traction reaches its limits on steep slopes. These are far from deal-breaking drawbacks, but they are worth bearing in mind. Ultimately, for anyone with a complex garden of up to 800 m², packed with obstacles and corners, the i208 LiDAR stands out as one of the best choices currently available.
