Segway Navimow i105E Review UK: The Default Wire-Free Choice
Last updated: 2026-07-05 · Prices checked against UK retailers on this date
This review is based on manufacturer specifications, UK retailer data and published third-party review information. We have not personally tested this model.
Quick verdict
The i105E is the mower we recommend most often, for an unexciting reason: it's the cheapest machine that does modern wire-free mowing properly. £699 buys RTK-plus-vision navigation, a 500m² rating that covers the typical UK garden, and the largest verified user base in its class — 2,000+ reviews averaging 4.4★ per 2026 roundups. Most rivals ask you to pay more or accept less.
Segway Navimow i105E
£699Best for: Small-to-medium UK lawns where you want wire-free setup without premium pricing — the sensible default for most gardens under ~400m².
Avoid if: Your lawn has heavy tree cover (RTK needs sky view), complex multi-zone layouts, or a genuinely steep bank.
Pros
- Cheapest credible RTK wire-free mower in the UK
- Huge verified user base (2,000+ reviews averaging 4.4★ per 2026 roundups)
- App remapping instead of wire re-digging
Cons
- Rated exactly 500m² — buy headroom, not the limit
- RTK positioning degrades under dense canopy
- No LiDAR at this price

Setup
Standard modern RTK routine: site the dock and antenna with decent sky view, walk the boundary with the app to draw the virtual map, mark no-go zones, set a schedule. Budget under an hour. The antenna placement is the only step that needs thought — it wants open sky, so a garden hemmed in by tall trees or buildings is the wrong home for this machine.
Cutting and navigation
RTK positioning means systematic lanes rather than the random bouncing of older wired mowers — the lawn gets covered efficiently and evenly. Like every mower in the category it cuts little and often, mulching clippings back into the lawn; expect to strim edges occasionally, as no mower in this price class edges perfectly.
Which gardens suit it — and which don't
- Great: open or lightly-treed lawns up to ~400m², simple or moderately awkward shapes, first-time buyers.
- Fine: gentle slopes, multiple zones the mower can walk between.
- Wrong machine: heavy tree canopy (RTK signal — consider the i208 LiDAR or Worx Vision), steep banks (no AWD — see the Luba Mini AWD), lawns at or above 500m².
Alternatives to consider
- Navimow i208 AWD (£899): +£200 buys 800m² coverage and all-wheel traction — the better buy for 400m²+ or damp, bumpy lawns.
- Eufy E15 (£1,499): easier setup (no antenna), better obstacle avoidance, but double the price and flat-lawn only — see the head-to-head.
- LawnMaster OcuMow 16 (~£292): if your lawn is under 150m², you may not need £699 of mower at all.
Price and availability
£699 on the official UK store at the time of checking, with periodic promotions (Navimow ran up to £200 off in spring 2026). Also stocked by Amazon UK and UK garden retailers — compare before buying.

FAQs
Is the Navimow i105E good for UK weather?
It's built to live outdoors like every mower in this class. As with all robot mowers, it cuts best on dry grass — schedule generously and let it skip wet windows.
Does the i105E need a boundary wire?
No — it navigates by RTK GPS plus a vision sensor. You map the lawn by walking the boundary with the app; changing the layout later is an app edit, not a re-dig.
What size lawn suits the i105E?
It's rated up to 500m², which makes it ideal for lawns up to about 400m². At a full 500m² it runs with no headroom — step up to the 800m²-rated i208 AWD (£899) instead.
i105E or i108E?
At current official prices (£699 vs £1,299) the i105E wins unless you specifically need 800m² coverage — and if you do, the £899 i208 AWD makes more sense than the i108E anyway.
