The Segway Navimow i215 is a premium robotic lawn mower that eliminates the hassle of boundary wires. It uses a combination of solid-state LiDAR and vision sensors to map and navigate your yard with precision, even on slopes up to 45%. This model is designed for homeowners with medium-sized lawns (0.37 acre) who want a hands-free, intelligent mowing solution that works reliably day or night.
Standout features include the True Drop and Mow capability, which lets you start mowing right out of the box without installing perimeter wires. The LiDAR and Vision Dual Fusion system ensures stable navigation without relying on GPS satellites, and the AI VisionFence detects over 200 obstacle types with 0.4-inch accuracy. In real-world use, this means the mower can avoid toys, garden tools, and even pets, while cutting cleanly along fences and pathways.
Build quality is robust, with off-road wheels and Electronic Stability Control that handle steep terrain effectively. The 100W motor and 6-blade disc provide a 7.1-inch cutting width and adjustable height from 2 to 4 inches, delivering consistent results on dense grass. The included Garage M (shipped separately) offers weather protection and a charging dock, though the separate shipment may delay full setup.
Potential drawbacks include the high price and the fact that the garage is not included in the main box. Additionally, with no user reviews yet, it's difficult to assess long-term durability. The 0.37-acre coverage is adequate for many suburban lots, but larger properties may need a second unit or a more powerful model. Some users may also find the app-based controls less intuitive than simple push-button operation.
Overall, the Segway Navimow i215 is a top-tier choice for tech-savvy homeowners with sloped, medium-sized lawns who value wire-free convenience and advanced navigation. If you're willing to invest in cutting-edge lawn care and can manage the separate garage shipment, this mower offers impressive performance and smart features that justify its premium price.

The Segway Navimow Access+ 4G Module is a dedicated accessory for the Navimow i1 Series robotic lawn mowers. It provides cellular connectivity as a backup when your home Wi-Fi signal is weak or unavailable, ensuring you can always control and monitor your mower from anywhere.

Standout features include the anti-theft tracking system, which gives you real-time location updates and alerts if the mower strays beyond its set boundaries. Additionally, the module enables weather-responsive scheduling: the mower checks forecasts every 10 minutes and adjusts its mowing plan to avoid rain, saving you time and preventing soggy turf. The promise of future smart features via firmware updates adds further long term value.
Design wise, the module is compact (5.5 x 4.84 x 1.29 inches) and lightweight (0.13 pounds), making it easy to attach to the mower. Installation is straightforward with the included 2.5 mm Allen wrench, and the black finish blends with the mower's aesthetics. The first year of 4G service is free, a nice bonus, though subsequent years require a subscription.
Potential drawbacks include the need for a paid subscription after the first year, which adds ongoing cost. Also, this module is exclusively compatible with the Navimow i1 Series, so owners of other models cannot use it. As a new product, there are no user reviews yet, making it hard to gauge real world reliability over time.
Overall, the Segway Navimow Access+ 4G Module is a valuable upgrade for i1 Series owners who depend on reliable connectivity and want enhanced security. Its cellular backup, anti-theft tracking, and weather-smart scheduling justify the investment, especially for those with weak Wi-Fi.

The Segway Navimow i210 AWD is a next-generation robotic lawn mower that eliminates the hassle of boundary wires. Designed for homeowners with sloped or uneven terrain up to 0.25 acre, it combines all-wheel drive with automotive-grade stability control to tackle slopes up to 45%. This mower is perfect for those who want a premium, tech-forward solution for lawn care.
Standout features include zero-turn steering that protects grass by avoiding lawn scraping, and a tri-frequency RTK vision system that maps your yard with centimeter precision in minutes.

Build quality is typical of Segway's robust design, and the included Garage S offers weather protection. However, the 7.1-inch cutting width is narrower than some competitors, meaning more passes to achieve a clean cut. The battery is sufficient for small to medium lawns but may limit larger properties within the 0.25 acre rating.
Potential drawbacks include the high price point and the lack of customer reviews at launch, which makes long-term durability uncertain. Additionally, the mower's weight of nearly 64 pounds could be challenging to move manually if needed.
Overall, the Segway Navimow i210 AWD is a powerful, wire-free mower with exceptional slope handling and smart mapping. It's best suited for homeowners with hilly lawns who value precision and convenience, provided their yard stays within the 0.25 acre limit and they are comfortable with the investment.
Buying Guide: What to Look For in a Wire-Free Robot Mower
Navigation Technology: RTK vs. LiDAR vs. Vision Fusion
Wire-free mowers rely on either RTK-GPS, LiDAR, or a combination of both plus cameras. The i108 uses EFLS Network RTK with a vision sensor, which gives it real-time corrections and reliable positioning even under tree cover. Higher-end models like the Segway Navimow i215 LiDAR Robot Lawn Mower Wire add solid-state LiDAR and dual vision for 3D obstacle detection. If your yard has many obstacles, LiDAR models offer extra precision. For open, simple lawns, RTK alone works perfectly.
Mowing Area and Battery Runtime
The i108 covers a typical lawn of about 0.25 acre on a single charge, thanks to a 5.1Ah battery. Its cutting width is 7.1 inches, and you can adjust height from 2 to 3.6 inches. If your lawn is larger, consider the Segway Navimow i215 LiDAR Robot Lawn Mower Wire, which handles up to 0.37 acre with a more powerful motor and wider cutting disc. The i210 AWD model also works for sloped terrain up to 45%.
Slope Performance and Traction
For hilly lawns, slope handling is critical. The i108 handles moderate slopes up to about 30% (17 degrees) thanks to its rear-wheel drive and electronic stability control. If your yard has steep banks up to 45%, the all-wheel-drive Segway Navimow i210 AWD Robot Lawn Mower Wire Free provides better traction with zero-turn steering that avoids turf damage. For flat or gently sloping lawns, the i108 is more than capable.
Smart Features and Security
All Navimow models offer app control, scheduling, and multi-zone management. The i108 includes GPS geo-fencing, lift detection, and auto-return in bad weather. For remote monitoring over cellular (not just Wi-Fi), the Segway Navimow Access+ 4G Module for Navimow i1 adds anti-theft tracking and instant weather updates. It is a worthwhile add-on if you travel often or have weak home Wi-Fi. Also, if you own a Navimow H series mower, the Segway Navimow Garage M for Navimow i215 LiDAR protects it from sun and rain, though it is not compatible with the i108.

Final Thoughts
The Segway Navimow i108 delivers a truly wire-free experience for small to medium lawns, with easy setup and reliable navigation. It is an excellent choice if you want a simple, hands-off mower without the hassle of installing boundary wires. For those who need more power on slopes or a larger cutting area, the Segway Navimow i210 AWD Robot Lawn Mower Wire Free offers all-wheel drive and zero-turn ability, while the Segway Navimow i215 LiDAR Robot Lawn Mower Wire adds advanced obstacle detection for yards with many trees and planters.
