Segway Navimow i105E

The spec-sheet read

Our analysis of the sourced spec sheet — positioning and trade-offs, not a hands-on review. We don't score mowers we haven't tested.

Segway's entry-level wire-free Navimow: Network RTK plus a VisionFence camera, no boundary wire and no local antenna, rated for lawns up to 500 m².

The Navimow i105E is the smallest of Segway's i-series and, at a £699 standard price, one of the lowest-priced wire-free robots in our catalogue — only the camera-guided Einhell FREELEXO CAM 500 and the Kress RTKⁿ 600 list for less. It navigates by 'fusion' — satellite positioning corrected over the mobile network (Network RTK) combined with a forward-facing VisionFence camera — so there is no boundary wire to bury and no RTK antenna to mount in the garden. Segway rates it for 500 m² with a 30% slope limit, an 18 cm cut and a 20–60 mm height range, at 10.9 kg with IP66 sealing and 58 dB(A). The 2.55 Ah battery is quoted at about 60 minutes of mowing against a 90-minute recharge.

Read it as a small-to-medium-lawn robot rather than a scaled-down flagship: the cut is narrow, the slope rating is moderate, and a 60-minute run means several charge cycles to work through 500 m². Its defining trade-off is what it leaves out — the solid-state LiDAR of the i208 we also list, and the all-wheel drive of the Mammotion and Dreame machines — in exchange for one of the lowest wire-free prices here. Because the RTK correction arrives over the network rather than from a local base station, signal coverage across the lawn matters more than it does for a wired machine; where that is doubtful, a wired Gardena or Husqvarna at similar area is the safer buy.

Verification note: Specs are quoted from Segway Navimow's official EU product page and cross-checked against an independent lab review of the i-series; the £699 is the standard price on the official UK store, with promotional discounts excluded. Warranty is not stated and is left unspecified. This is a reading of the published specification, not a hands-on test.
