What it handles

Two-wheel drive, which caps how steep it can work. That is a flat-to-gently-rolling rating — a real slope will stall it.

Navigation is satellite-based without vision or LiDAR, so heavy tree cover is a real risk — it loses its fix under canopy.

Below a quarter acre once the coverage buffer is applied — too small for any of our acreage bands.

How confident we are

Cross-checked against the manufacturer and at least one other source.

Slope corrected from 45% to 30%: the 45% figure belongs to the i2 AWD series, not the i1 series. Official Segway i-series manual gives 30% inside the work area and 10% at the boundary. Segway EU spec page shows 45% and 1500 sq m for this model, contradicting Segway own manual - manual treated as authoritative.
