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.
Pros
- Significantly improves traction on wet and muddy terrain
- Simple bolt-on installation with all hardware included
- Robust construction that holds up against rough use
- Compatible with two popular Navimow i Series models
- Helps prevent mower from getting stuck on slopes
Cons
- Only fits Navimow i105N and i110N, not other mower models
- Heavier than standard wheels, may slightly reduce run time
- Aggressive tread could mark delicate turf if turned too sharply
The Segway Navimow Traction Wheel kit is a purpose-built upgrade for owners of the Navimow i105N and i110N robotic mowers. If your lawn has muddy patches, steep slopes, or wet grass that leaves your mower spinning its wheels, this set of cleated 9.8-inch tires offers a practical solution. It is designed for anyone who wants their robot mower to handle the trickiest parts of the yard without constant intervention.
The standout feature is the aggressive spike tread that bites into soft or slick surfaces. Segway claims the wheels handle inclines up to 35 percent, which is significantly steeper than what standard wheels can manage. In real-world use on wet grass and loose soil, the traction is noticeably superior, and the mower maintains forward momentum where it would otherwise stop or slide sideways.
Installation is straightforward: the package includes an Allen wrench and six screws, so you can swap both wheels in about ten minutes. The wheels themselves feel sturdy, with a thick rubber compound and reinforced hubs that should survive repeated contact with rocks and roots. They are a bit heavier than the factory wheels, but the trade-off in climbing ability is worth it for challenging lawns.
The main limitation is compatibility: the wheels are specifically sized for the Navimow i Series (i105N and i110N), so they won't fit other mowers. Also, the added weight and aggressive tread may slightly reduce battery runtime and could scuff delicate turf if you make frequent sharp turns. These are minor trade-offs for the dramatic improvement in grip.
Verdict: If you own a Navimow i105N or i110N and struggle with traction on slopes, mud, or wet grass, this traction wheel kit is a worthwhile investment. It is easy to install, well-built, and delivers exactly the off-road capability the standard wheels lack. For the asking price, it transforms your mower into a more reliable performer on uneven ground.

Buying Guide: What to Look for in a Navimow for Slopes
Slope Capability
The most critical factor is the maximum incline the mower can handle. Navimow models range from 45% (about 24 degrees) to an impressive 84% (40 degrees). For moderately sloped lawns, a 45% rating from the i series is sufficient. But if you have steep hills or retaining walls, the X series with 4WD and dual suspension offers unmatched climbing power.
Navigation Technology: LiDAR vs. RTK
Wire-free mowers rely on either LiDAR or RTK GPS for mapping and obstacle avoidance. The i215 uses solid-state LiDAR and vision fusion for accurate day-and-night navigation without satellites. The i206 and i210 use EFLS Network RTK with Vision for centimeter-level GPS precision. For shaded yards or areas with poor sky view, LiDAR is more reliable. For open slopes, RTK works beautifully.
Drive System: AWD vs. 4WD
All-wheel drive (AWD) provides power to all wheels for better traction on uneven ground. The i210 and i206 AWD models include electronic stability control and zero-turn steering to prevent turf damage. The X430 goes further with true 4WD, dual independent steering motors, and an ORV-tuned suspension that can cross obstacles up to 2.8 inches. If your lawn has ruts or roots, 4WD is the way to go.
Cutting Performance and Coverage
Consider your lawn size and grass type. The i series covers 0.15 to 0.37 acres per charge with a 7.1-inch cutting width. The X430 covers up to 1 acre with a 17-inch dual-disc system and automatic height adjustment from 0.75 to 4 inches. For dense or fast-growing grass, the X430’s dual 180W motors and 12 blades provide efficient mulching. For smaller sloped lawns, the i210 AWD offers a great balance of power and runtime.
