Segway Navimow i105/i108 vs i2 AWD: old i Series or new i2?

Who each one is for

Both are Segway Navimow's compact, wire-free mowers for small lawns, with a single camera for obstacles and 180 mm cuts. The i2 AWD is the 2026 replacement for the i Series (which Navimow now labels i1).

The Segway Navimow i Series (i1) suits small, flat, open lawns where you're happy to mount an aerial, and gardens where mobile signal is weak. It's only worth buying at a clear discount.

The Segway Navimow i2 AWD suits small lawns with some slope or bumpy ground, in gardens with an open sky and decent mobile coverage, for owners who want nothing to install beyond the charging station.

Navigation

Both use RTK satellite positioning plus a camera, and both are vulnerable to heavy tree cover and tall buildings. The difference is where the corrections come from.

The i Series needs its own RTK aerial, installed near the charging station. It's a self-install job, but it's an extra step and another thing in the garden. The upside is that it doesn't depend on your phone network.

The i2 AWD gets its corrections from Navimow's network RTK service over built-in 4G, so there's no aerial. The catch is that it needs usable mobile coverage at the lawn; Navimow's UK site has a postcode checker. If your garden is shaded or your signal is poor, look at the Segway Navimow i2 LiDAR instead. Our network RTK and 4G guide explains what to check.

Slopes and access

This is where the i2 AWD pulls clearly ahead. A driven third wheel gives it all-wheel drive and a 45% slope rating. The i Series is rated for 30%, and its manual limits slopes at the edge of the mapped area to 10%. See our slopes guide.

The i Series also asks for passages of at least 100 cm between areas, which rules out many side paths. Navimow doesn't publish a figure for the i2 AWD.

Lawn size

The i Series covers 500–800 m² and the i2 AWD 500–1,000 m². For a lawn between 800 m² and 1,000 m², only the i2 fits.

Cutting

Both cut 180 mm wide with height set by hand from 20 mm to 60 mm. The i2 AWD's disc carries five blades against three on the i Series. Neither offers app-set height; the i2 LiDAR does.

4G, subscription and security

Neither needs a subscription to mow. The i2 AWD has 4G built in with 12 months of data, which covers remote control and GPS tracking; after that, remote features need a paid renewal. The i Series has Wi-Fi and Bluetooth only, and 4G and GPS tracking need Navimow's separately sold Access+ module, which also becomes a paid renewal after its first year. Both have a PIN lock.

Noise

The i Series manual declares 58 dB(A) to the European mower standard. Navimow quotes 59 dB(A) for the i2 AWD without stating the test conditions; the same figure on the i2 LiDAR is measured with no cutting load. They're likely similar in practice, but the i Series figure is the more rigorous one.

Warranty and price

Both have 3 years on the mower and two years on the battery. The i Series starts from £699 and the i2 AWD from £799. Both were sold out on Navimow's UK store at the time of writing, so check retailer stock.

Verdict

For almost everyone, the i2 AWD is the better small-lawn mower. It drops the aerial, handles steeper ground, covers more area and includes 4G tracking. It's not for heavily shaded gardens or poor-signal locations.

The i Series is only worth it if you find one well below an i2 AWD, have a flat, open lawn, and either can't rely on 4G or don't mind adding the aerial. Don't choose it for any lawn with a meaningful slope.
