In 2024, Segway changed the industry with the Navimow i105. It was cheap, it was camera-based, and it worked.
But it had two weaknesses: it slipped on hills, and it lost signal under big trees.
Fast forward to 2026, and Segway has released the i2 Series to fix exactly those problems. But they didn’t just release one robot; they released specialized tools. Now, the lineup is a mix of five specific models:
- The Budget Kings: i105 & i110
- The Hill Climbers: i206 AWD & i210 AWD
- The Tree Master: i215 LiDAR
Which one fits your lawn? Let’s break down the specs, the prices, and the pain points.
The Classics: Navimow i105 & i110
Best For: Flat, open, budget-conscious lawns.
These are the models that made Segway famous.
- The Price: Starting at $799 (i105), this remains the best value in the robot mower world.
- The Weakness: They are Front-Wheel Drive (FWD). If you have a slope greater than 30% or wet grass, these units struggle. In fact, many users (myself included) had to buy aftermarket “Traction Spikes” to keep them moving in the mud.
- The Verdict: If your lawn is a simple, flat rectangle with open sky, save your money. The i105/i110 is all you need.
The Climbers: Navimow i206 AWD & i210 AWD
Best For: Slopes, wet grass, and complex terrain.
This is the upgrade we have been begging for. The “AWD” stands for All-Wheel Drive.
- The Upgrade: Segway added motors to the rear wheels. The i206 AWD ($999) can now climb slopes and navigate muddy divots that would trap the older i105.
- The Sweet Spot: The i206 AWD is priced at $999. This is a direct shot at Mammotion. You get premium AWD traction for under a thousand dollars.
- The Verdict: If you have hills, berms, or drainage ditches, spend the extra $200 for the AWD. It eliminates the “Robot Stuck” notification.
The Specialist: Navimow i215 LiDAR
Best For: Dense tree cover and “GPS Dead Zones.”
While the other robots rely on Satellites (RTK) and Cameras, the i215 LiDAR adds a Laser Radar turret on top.
- The Problem it Solves: Cameras can be blinded by lens flares, and GPS is blocked by oak trees. LiDAR sees through all of that. It maps the yard instantly and navigates with centimeter precision even in total shade.
- Capacity: It also boasts a larger battery capacity (0.37 acre) compared to the entry-level models.
- The Verdict: Buy this ONLY if you have heavy tree canopy or narrow corridors between tall houses where GPS signal fails.
