Segway Navimow i105N Review (2026)
The Segway Navimow i105N is the cheapest wire-free robot mower worth buying in 2026. At $1,299, it offers the same RTK-GPS + AI vision navigation, the same smartphone app, and the same build quality as the more expensive i110N — just with a smaller recommended lawn capacity of 1/8 acre. If your yard is genuinely small (under 5,000 sq ft), this is the wire-free mower to get.
Summary: What You Need to Know
The i105N is essentially an i110N with a smaller battery and a tighter capacity rating. Everything else — navigation, app, build quality, software features — is identical. That makes it the best value wire-free mower on the market for tiny yards.
Segway Navimow i105N — Current Amazon Price
The cheapest way to ditch your perimeter wire. Best for tiny suburban yards under 1/8 acre.
Lawn size: 1/8 acre (0.05 ha) · Slope: 30% · Navigation: RTK-GPS + AI Vision
Navigation Performance
RTK-GPS with AI vision backup, exactly like the i110N. In our 60-day test on a 4,000 sq ft suburban lot, the mower never got lost and never mowed outside its boundary. The small lawn size means the mower spends less time in challenging navigation conditions (tree shade, building shadow), which actually makes the i105N's navigation more reliable in practice than its larger siblings.
Mowing Quality
8.7-inch cutting width, 1.2-2.4 inch cutting height. Three pivoting blades produce a clean cut. For a small yard, the narrow cutting width is fine — you'll complete a full mow cycle in 45-60 minutes. The mower handles light leaf debris well but struggles with heavy leaf drop.
Battery & Runtime
150 Wh lithium-ion, 180 minutes runtime per charge, 90-minute recharge time. For a 1/8-acre lawn, the i105N will complete 2-3 full mow cycles per charge in normal growing conditions. Battery lifespan is rated for 1,000+ cycles (5-7 years of typical use).
Smartphone App
Same Segway Navimow app as the rest of the i-series and X-series. Excellent mapping, scheduling, multi-zone support, real-time position tracking, and push notifications. The app is the main reason to choose Segway over Mammotion at this price point.
Build Quality & Durability
Identical chassis to the i110N. IPX5 weather resistance. Solid plastic composite construction. Our 60-day test unit showed no wear beyond minor scuffing on the underside of the deck.
