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

Narrow passages, dense borders, twisting corners… the Segway Navimow i208 LiDAR claims it can tackle gardens that entry-level robot mowers fear. We put it through two months of demanding use on a tricky plot to find out whether its €1,199 price tag is warranted.

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

However, several navigation technologies are now competing for attention: RTK, AI vision, LiDAR, wide-angle cameras, all sometimes at very similar prices. As a result, matching a model to your particular needs can be difficult.

Take a practical example. In 2026, a wire-free robot mower can be found for around €600, as with the Mova ViAX 250. The compromise is that its navigation system does not include LiDAR and its maximum coverage is limited to 250 m².

At the other end, the Roborock RockNeo Q105 claims to handle areas of up to 500 m². It still has no LiDAR, but this time it uses an antenna. Then there are manufacturers with especially extensive ranges, including Mova and, above all, Segway Navimow, which introduced around 20 new models last spring.

Into this crowded market comes the Navimow i208 LiDAR. With its three sensors, this wire-free robot is aimed less at small, open lawns than at challenging gardens packed with narrow routes, borders and thick vegetation. It is designed for areas of up to 800 m² and launched at €1,199. If that describes your garden, this review is for you.

What we liked

Quick, intuitive installation

For Segway, 2026 represents a turning point. None of the new robot mowers unveiled by the brand in spring requires a wire to be buried around the lawn, nor an unsightly antenna positioned in the middle of the garden.

Like the other models in its range, the i208 LiDAR needs only its charging station, placed in a spot that receives your home Wi-Fi signal. Once it is connected, along with Bluetooth pairing, the robot is nearly ready to get to work.

There are two ways to set it up. The first, and most traditional, puts you in control. Using a virtual joystick on your smartphone, you drive the robot around the edges to define the garden's outline. It takes a little skill, particularly on a plot with plenty of corners.

The second option, which is becoming increasingly common on recent LiDAR models, is automatic mapping. Here, the Navimow i208 LiDAR explores the lawn and creates its own map. In practice, this feature is best reserved for straightforward square or rectangular gardens with few obstacles - effectively the opposite of the terrain for which this mower appears to be designed.

Once the map has been created, you can view it in 3D and add exclusion zones, boundaries and passage points. This is an important stage, as it largely determines how well the robot will navigate afterwards. For our initial 250 m² area, installation and mapping took just 45 minutes in total.

Segway Navimow i208 LiDAR navigation and a comprehensive app

This is where the Navimow i208 LiDAR really stands out. To navigate without an antenna, the robot relies on a three-sensor system: LiDAR to scan its surroundings, even in low light; a wide-angle camera to identify obstacles; and satellite positioning to establish its location.

Its performance lived up to the demanding route we set for it. Our test area included numerous planted borders, trees with large exposed roots, flowerbeds surrounded by stones, garden furniture and small winding corners. These were all potential traps that never caught out the Navimow i208 LiDAR.

Over our two-month test period, we never had to free it manually from an awkward situation. Better still, we placed obstacles in its path unpredictably to push it harder, and it avoided them without any trouble.

On the software side, the Navimow app is fairly feature-rich without becoming confusing. Cutting height can be adjusted by zone from 20 to 70 mm, while you can also select the direction of the stripes to avoid marking the lawn. Very little is missing: you can schedule operating times, lock the controls to keep children safe, and use a rain sensor to prevent it from working during a storm.

Segway even goes as far as allowing you to create a heart or a letter in the grass. If you have an artistic side, or an original marriage proposal to make, it is there if you want it.

Neat mowing and careful build quality

Turn the Navimow i208 LiDAR over like a tortoise and it reveals a six-blade cutting deck, capable of mowing a width of roughly 22 cm. That is not the widest on the market - certain models reach 26 cm - but the result is highly satisfying.

When mowing, the robot progresses in properly parallel stripes. It remains methodical from beginning to end. Where other mowers can seem to wander randomly, like headless chickens, this one never appears lost. The cut is clean and, most importantly, very even.

Hardly any stray blades or clumps of grass remain after it passes. Hardly any, because another benefit of its excellent navigation is that the small flowers occasionally found in its route are carefully avoided and left intact. There is no need to turn daisies into exclusion zones either.

What we liked less

Edges remain an enduring problem

Much as robot vacuum cleaners are generally unable to remove dust from tiny corners, robot mowers face a similar limitation: cutting right up to the edges. This is currently one of the major battlegrounds in garden mowing, with each manufacturer trying to find a solution.

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

In practical terms, during a normal mowing session, the robot always starts by following the boundaries before filling in the centre. It moves as close as possible, leaving only around 5 cm uncut. Along a gravel path or a perfectly level patio, this works well, as it almost overlaps the edge.

Against a wall or dense vegetation, however, there is no miracle. As its deck does not extend sideways, it leaves around 10 to 15 cm of uncut grass. Those who want a perfectly immaculate finish will still have to use hand shears.

Wheels can slip, while charging is somewhat slow

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

That said, we noticed that its wheels can slip in places as soon as the ground becomes loose or waterlogged after rain. It is not a major issue: it can navigate a complex garden, but do not expect it to perform like an all-terrain machine on very steep, muddy sections.

Its battery life is rather good. 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 solid two hours before returning to work. Taken together and measured against its maximum 800 m² coverage, expect around four mowing and recharging cycles, or a good 12 hours spread across one or two days.

A few other minor shortcomings

A handful of details prevent the Navimow i208 LiDAR from delivering a flawless performance. First, mowing customisation is somewhat limited for a robot at this price. You cannot choose the order in which it treats the various zones, how many times it travels along the edges, or the speed at which its blades rotate. In short, every mowing session is treated the same way.

Next is the 4G module. Its purpose is to let you control the robot even when you are outside Wi-Fi range. If you go on holiday, for example, you can start a mowing session or receive an alert if someone tries to take it away. Its GPS chip can then be used to locate it. Unfortunately, this convenience is included only for the first year. After that, it costs €30 per year to retain access.

Finally, although the robot itself feels robust, the same cannot be said for its charging base. Its small orange accents add a little character, but it is still covered in very thin plastic, of the kind more commonly found on cheaper models. Should you want to add a garage to shelter the robot from rain, you will need to spend another €149. These extras can quickly increase the total bill.

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 no larger than 500 m², more affordable models under €1,000 can be sufficient. That is the case with the Roborock RockNeo Q105 and Mova ViAX 250, both of which we tested recently.

Once the garden becomes more complicated, however, with planted borders, vegetation, a patio, gravel paths or narrow passages, the situation changes. This is what we call a complex garden, and LiDAR navigation becomes essential for this type of plot.

That is exactly what the Navimow i208 LiDAR offers. Its three-sensor system provides exceptionally precise navigation and obstacle recognition. Installation is also quick, with no antenna to install, the cut is neat, and the app is fairly comprehensive.

It is not perfect, though. Edge performance still needs improvement, while traction reaches its limits on steep slopes. These are far from deal-breakers, but they are worth bearing in mind. Ultimately, for anyone with a complex garden of up to 800 m², full of obstacles and awkward corners, the i208 LiDAR ranks among the best choices currently available.
