How they differ in real use
Built from our robot lawn mowers small yards scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Segway Navimow i105N and the Gardena SILENO City made our Top 5 Robot Lawn Mowers for Small Yards, at #1 (best overall) and #3 (best value). The best balance of convenience, capability, and price for a small yard. The i105N is fully wire-free — RTK plus a 140-degree VisionFence camera let you map the lawn by walking the boundary with your phone — and its AI recognizes 150+ obstacle types rather than bumping into them. At its mid-tier price it undercuts the other wire-free picks while covering everything a compact lawn needs, which is why it takes the top spot over the more expensive eufy and Mammotion. The cheapest mower here and the quietest, at a class-leading 57 dB(A). The trade-off is a one-time boundary-wire install and bumper-based collision sensing instead of a camera. For a buyer who wants a proven, low-drama cut on a compact city lawn and doesn't mind laying a cable once, the SILENO City is the value champion — it ranks below the wire-free picks only because that install effort and the lack of obstacle avoidance are real compromises.
We score robot lawn mowers for small yards on Setup & Navigation (25%), Cut Quality & Coverage (20%), Smart Features & Obstacle Handling (20%), Quiet Operation (10%) and Value (25%). On that basis the Segway Navimow i105N totals 9 out of 10 and the Gardena SILENO City 8. The widest gap is Setup & Navigation, where the Segway Navimow i105N scores 9.2 against 6.8 for the Gardena SILENO City — wire-free vs boundary-wire install and mapping reliability on a small, tight lawn. Smart Features & Obstacle Handling also separates them: 8.6 for the Segway Navimow i105N versus 6.8 for the Gardena SILENO City. The Gardena SILENO City claws back ground on Quiet Operation.
On paper, the specifications that actually differ: Coverage Area — Up to 1/8 acre (~5,400 sq ft) on the Segway Navimow i105N versus Up to 2,700 sq ft on the Gardena SILENO City; Navigation — RTK + Vision (EFLS 2.0), wire-free on the Segway Navimow i105N versus Boundary wire + patented random pattern on the Gardena SILENO City; Perimeter Wire — Not required on the Segway Navimow i105N versus Required (included) on the Gardena SILENO City; Max Slope — 30% (17°) on the Segway Navimow i105N versus 35% (19°) on the Gardena SILENO City; Cutting Width — 7.1 in on the Segway Navimow i105N versus 6.3 in on the Gardena SILENO City; Cutting Height — 1.2–2.4 in (app-adjustable) on the Segway Navimow i105N versus 0.8–2.0 in on the Gardena SILENO City.
Pricing as of July 20, 2026: $669 for the Segway Navimow i105N and $631 for the Gardena SILENO City, a $38 difference in the Gardena SILENO City's favor. Owners praise the Segway Navimow i105N for fully wire-free RTK + Vision setup — no perimeter cable to lay and camera recognizes 150+ obstacle types instead of just bumping into them; the most common complaint is RTK relies on a clear sky view — heavily wooded lots can lose signal. Owners praise the Gardena SILENO City for lowest price of the group for a compact city lawn and 57 dB(A) is the quietest here — genuinely patio-and-neighbor friendly; the most common complaint is requires laying a boundary wire — the most setup effort here.
