Segway Navimow X420 Review: The AWD Robotic Lawn Mower for Challenging Gardens

With the Navimow X420, Segway is introducing a robotic garden mower that’s intentionally not designed for well-maintained small gardens, however is meant primarily for big, difficult gardens with slopes, roots, edges, and different terrain. As an all-wheel-drive mannequin with 4 pushed wheels, wi-fi navigation, and an space protection price that’s unusually excessive for this class of gadget, the X420 clearly positions itself within the premium section. I took a better take a look at this strong robotic mower and examined how its spectacular options carry out in on a regular basis use.

What’s Included with the Navimow X420

• Navimow X420 Robotic Lawn Mower
• Charging station
• External RTK reference antenna (non-obligatory; not required for operation)
• Power adapter and energy twine
• Replacement blade set
• Mounting {hardware} for charging station and storage
• Quick Start Guide and Documentation

Design and Build Quality of the Navimow X420

It turns into clear as quickly as you unpack it: The X420 isn’t a tool for a compact suburban yard. Weighing just below 29 kilograms and measuring roughly 85 × 61 × 35 centimeters, it seems to be extra like a small off-road automobile than a traditional robotic garden mower.

The massive wheels and durable development additional reinforce this impression. The construct high quality is top-notch: the gaps are uniform, the plastics used really feel high-quality, and the complete construction offers off a strong impression.

The distinction in measurement in comparison with the charging station is hanging; the station is sort of compact relative to the robotic garden mower itself, so the X420 solely partially rests on it whereas charging. On the highest of the robotic is a small shade show together with a management panel.

A standing gentle additionally signifies sign energy, and the extremely seen purple cease button permits for an emergency cease if essential. On the entrance are numerous cameras for navigation and impediment detection.

For emergencies, there’s additionally a sturdy bumper beneath. The carrying deal with on the rear, then again, permits you to transport this colossus, which weighs almost 30 kg. On the underside, the twin mower deck—and the intriguing entrance axle—naturally catch your eye at first look.

Setup and Commissioning

Installation is accomplished solely with out boundary wires. Although the package deal contains an exterior RTK antenna that originally appears necessary, its use is definitely non-obligatory. In the app, you may select whether or not to make use of the inner antenna or the exterior RTK answer.

The solely essential requirement is a secure Wi-Fi connection on the charging station’s location; it’s not essential elsewhere within the yard. For mapping, you may select between an computerized digicam scan and a guide possibility, by which the robotic is guided throughout the garden like a remote-controlled automobile.

In apply, guide mapping delivers extra exact outcomes, which is why it’s the really useful technique. However, I used to be additionally glad with the outcomes of computerized mapping, since my take a look at backyard has very straight boundaries anyway.

A minor quirk turns into obvious when turning throughout mapping: The entrance wheels have a really large steering angle, which often causes the robotic to get in its personal method in tight conditions. During the take a look at, it briefly acquired caught between a bucket and an umbrella stand.

However, it freed itself from this predicament by itself after a number of seconds. Additionally, the robotic couldn’t be steered in reverse. This is considerably stunning, since reverse steering was doable with none points in distant management mode.

However, these quirks not matter throughout subsequent autonomous mowing. Once property boundaries, restricted zones, and passageways have been mapped, a whole map is generated inside a couple of minutes, which the X420 makes use of to function autonomously.

Navimow App

Control is dealt with by way of the Navimow app, which carried out constantly properly in our exams. During setup, it stands out for its sensible, step-by-step steerage—comparable to directions on the required clearance in entrance of and beside the charging station. During operation, mowing zones, restricted areas, and schedules may be clearly managed; the chopping peak may be set individually for every zone; and a traction management characteristic ensures gentler dealing with on moist or smooth surfaces.

All of that is complemented by detailed mowing reviews that present a superb overview of the work accomplished. Compared to some rivals, nevertheless, the chopping peak can solely be adjusted in 5-millimeter increments relatively than 1-millimeter increments. The X420 additionally lacks a reside video feed from the robotic’s digicam, a characteristic provided by some competing fashions. That’s a disgrace, for the reason that essential digicam expertise is definitely in-built.

Navigation and Obstacle Detection

Navigation is likely one of the X420’s biggest strengths. Instead of a standard RTK base station, Segway Network combines RTK by way of mobile networks with a 360° digicam system and visible positioning. This permits the robotic to keep up very exact positioning even underneath bushes, alongside fences, or in difficult radio environments.

In addition, the Navimow is extraordinarily maneuverable, due to its Xero-Turn all-wheel drive (AWD) system. The 4 individually pushed wheels characteristic eccentric front-wheel steering, which ensures a particularly small turning radius. In apply, nevertheless, I used to be significantly impressed by the impediment detection. Bushes and shrubs are reliably acknowledged as such relatively than handled as fastened obstacles, and even transferring objects like pets are detected and safely navigated round.

The X420 even handles slim passages lower than one meter large with ease. The Navimow additionally reliably detected smaller objects comparable to tennis balls. And if an individual will get too near the robotic mower, it routinely pauses briefly. This isn’t annoying in any respect; as soon as you progress away, it resumes mowing by itself.

Mowing Performance of the Navimow X420

When it involves precise mowing, the X420 performs at a excessive stage. The dual-disc chopping system, with a complete of twelve blades and a chopping width of a full 43 cm, mixed with its excessive journey velocity, ensures above-average space protection—a characteristic that basically comes into its personal on massive lawns.

Even dense or damp vegetation is reliably dealt with by the 2 highly effective chopping motors with out the mower changing into clogged. After a number of passes, the lower seems even and clear. Given the large chopping peak vary of 25 to 95 mm, there’s one thing for everybody. When it involves edge chopping, nevertheless, the image is extra nuanced.

Without a separate trimmer module, relying on the sting peak, a residual strip starting from a number of centimeters to about ten centimeters stays if the garden edge is considerably increased than the garden itself. The EdgeSense perform, which may be activated, permits the robotic to get nearer to edges, visibly decreasing the strip of grass left alongside the sting.

Due to its rectangular design, some grass naturally stays within the corners. Its lawn-friendly operation is especially noteworthy: TÜV certification within the “Lawn Care” class confirms that, after a simulated one-year steady operation, there may be solely minimal visible harm to the turf—even through the turning maneuvers typical of all-wheel-drive mowers.

Conclusion on the Navimow X420

The Segway Navimow X420 isn’t a robotic mower for small, flat decorative lawns—it’s merely outsized for that software. Its true house is massive, difficult properties with slopes, roots, edges, and ranging terrain. That’s precisely the place it actually shines: highly effective all-wheel drive, wonderful climbing potential, exact and dependable navigation with no boundary wire, above-average protection, and a driving fashion that’s noticeably light on the garden.

The solely actual compromise is in edge trimming. Its excessive worth clearly positions the X420 within the premium section, however for many who repeatedly should deal with tough terrain and preserve a garden of as much as 2,000 m², this can be a technically refined all-in-one package deal that delivers on its guarantees in apply throughout almost each class.
