Lawn Coverage and Use Case Suitability
The Navimow i105 is designed to serve lawns up to 500 square meters, making it a perfect fit for small suburban lots, compact gardens, and homes with limited green space. It’s efficient in straightforward layouts and offers seamless wireless operation without the need for perimeter cables. Its small footprint and nimble turning make it ideal for areas with flowerbeds, narrow paths, or landscape borders.
The Navimow i108 expands the working area to 800 square meters, giving homeowners with larger properties broader mowing coverage in fewer sessions. Whether you’re dealing with a larger backyard, multiple lawn zones, or an L-shaped plot, the i108 is better suited for maintaining those with more consistency.
Winner: Navimow i108
Its extended coverage gives it more versatility and fewer mow cycles for medium-sized properties.
Battery Capacity and Runtime Performance
Equipped with a 5.2Ah lithium-ion battery, the i105 can mow for up to 120 minutes per charge. It’s well-matched for its coverage area, ensuring that a single charge can usually handle the entire mapped space with moderate grass density.
The i108, on the other hand, includes a larger 7.8Ah battery, which extends runtime to 180 minutes. This is a significant advantage when covering more terrain or mowing in zones with thicker growth. The longer runtime reduces the frequency of charging and can complete larger mowing cycles without interruption.
Winner: Navimow i108
With 50% more runtime and increased capacity, it provides greater efficiency and less downtime.
Both the i105 and i108 use Segway’s industry-leading RTK-GNSS positioning system combined with the proprietary EFLS (Exact Fusion Locating System). This system uses centimeter-level satellite accuracy to map and maintain virtual boundaries without the need for perimeter wire installation.
Each mower is paired with a VisionFence sensor, a camera-based system mounted at the front of the unit, which helps it detect and classify real-world boundaries and visual obstacles. This hybrid approach enhances the mower’s ability to operate in GPS-challenged areas, like near trees or buildings, and enables smarter navigation decisions in real time.
Winner: Tie
Both models offer the same premium navigation system with visual assistance and wireless boundary mapping.
Cutting Width and Blade Adjustability
The cutting deck on both models measures 210 mm, ideal for precision mowing in smaller yards and around curved borders. Though compact, this cutting width strikes a balance between tight maneuverability and effective area coverage.
Each model offers a cutting height range between 20 mm and 60 mm, adjustable through the Navimow app. This enables users to fine-tune the mower for seasonal grass growth or personal aesthetic preferences. The motors maintain consistent blade speed, ensuring uniform cuts across flat and uneven surfaces.
Winner: Tie
Cutting performance is identical in both models, ensuring reliable and customizable trimming quality.
AI Obstacle Avoidance and Safety Systems
Both the i105 and i108 are equipped with Segway’s VisionFence sensor, which uses AI to detect and recognize objects like toys, pets, people, or trees before contact occurs. This camera-based system is supported by ultrasonic proximity sensors, enabling preemptive speed reduction or rerouting when objects are detected.
The result is a mower that operates safely in dynamic, obstacle-filled environments, adjusting its behavior based on what it “sees” in front of it. Tilt and lift sensors ensure blade stoppage when the unit is lifted, adding another layer of operational safety.
Winner: Tie
AI-enhanced vision and ultrasonic sensors provide the same level of intelligent, collision-free mowing.
Smart Features, App Integration, and OTA Updates
Both the i105 and i108 integrate with the Navimow app, accessible via Bluetooth and Wi-Fi. The app allows full control over mowing zones, cutting height, schedules, and no-go areas. Users can view the live position of the mower on a virtual map, receive notifications, and initiate firmware upgrades with one click.
App setup includes walking the perimeter with your phone during initial mapping, after which zones can be edited, added, or subdivided directly on the screen. OTA updates ensure the mowers evolve with improved navigation, new AI recognition patterns, and software enhancements released by Segway. Functionality and responsiveness are identical on both models.
Winner: Tie
Both offer equally advanced smart features and user-friendly control with future-proof updates.
Slope Handling and Traction
The slope capability of both models is rated at 30% (17 degrees), making them suitable for moderately sloped lawns and slightly uneven terrain. While not intended for steep hills, they handle standard residential grade changes, curbs, and minor inclines effectively thanks to their low center of gravity and responsive traction control.
Both units use textured rubber wheels for improved grip on damp or grassy surfaces. When paired with their intelligent route planning, the result is a smooth and steady mowing experience, even on curved or contoured landscapes.
Winner: Tie
Equal slope rating and drive performance deliver solid results on typical residential gradients.
Noise Output and Environmental Friendliness
Each mower operates at under 58 dB(A), making them significantly quieter than traditional gas-powered equipment and ideal for residential use in noise-sensitive communities. They can run early in the morning or during the night without causing disturbances.
Their electric motors produce zero direct emissions, contributing to cleaner air and a lower carbon footprint. Combined with energy-efficient drive systems and intelligent charging cycles, they offer a truly green mowing solution.
Winner: Tie
Noise levels and eco-performance are matched, delivering whisper-quiet and sustainable operation.
Water Resistance and Outdoor Durability
Both the i105 and i108 are certified IPX6 waterproof, capable of withstanding high-pressure water jets from any direction. This allows users to hose off mud, grass clippings, or debris after a session. The exterior shell is UV-resistant and built to endure exposure to harsh weather conditions like sun, wind, and light rain.
Their internal electronics are sealed and shock-absorbed, ensuring that impacts, bumps, and accidental drops do not affect long-term operation. The wheel hubs and blades are built from rust-resistant metals, minimizing the need for repairs or replacements.
Winner: Tie
Both models are engineered for outdoor longevity with robust weather and water protection.
Price and Value Comparison
The Navimow i105 offers excellent value for small yards, combining precision mowing with high-end features like RTK and VisionFence at an accessible price point. It’s ideal for homeowners who don’t need to cover more than 500 m² and want to keep costs lower without sacrificing technology.
The Navimow i108, while priced higher, delivers more runtime, greater coverage, and fewer recharges. It pays off for users who require extended mowing sessions and don’t want to compromise on lawn size compatibility.
Winner: Depends on Lawn Size
Choose the i105 for cost-effective, tech-rich mowing in small gardens. Choose the i108 for larger lawns and maximum efficiency per session.
Conclusion
Choose the Navimow i105 if you’re managing a compact lawn with tight borders, want high-end navigation and safety features, and prefer faster recharging between sessions. It’s the perfect entry into wireless robotic mowing without compromising on intelligence or convenience.
Choose the Navimow i108 if your lawn spans closer to 800 square meters and you want longer runtime, fewer mow interruptions, and expanded zone flexibility. It offers the same premium features as the i105, but scales better for more demanding property layouts.
Overall Winner: Navimow i108
With its longer runtime, increased area capacity, and equally advanced AI-driven performance, the i108 stands out as the more versatile, future-ready robotic mower for homeowners who want full-featured, boundary-free mowing with fewer limitations.
