The short version

The i2 LiDAR is the middle of Navimow's new i2 family. It sits between the i2 AWD, which steers mostly by satellite, and the pricier Pro version. A spinning laser scanner on the front builds a picture of the garden, and a camera spots obstacles, so it keeps its bearings under trees and next to walls, where satellite-only mowers get lost. Satellite corrections over the mobile network help too, and there's no wire or aerial to fit. It comes in four sizes, from the 800m² i208 to the 2,000m² i220.

What you give up is simplicity at the start and a finished edge. One tester couldn't get automatic mapping to work and drove the boundary by hand, and another had to redraw a corner after the mower tipped off it. The cut is 22cm wide, but the blades sit under the body, so borders still need a strimmer. 4G data is free for the first year only. It's £1,099 at the cheapest retailer we track.

Our take: Buy it if your lawn is at least a few hundred square metres and has trees, tall hedges or buildings that block the sky. That's where the laser earns its keep, and four reviewers found it cuts neatly and quietly. On an open, sunny lawn under 1,000m², the Navimow i2 AWD does a similar job. If trimming the edges bothers you most, look at the Ecovacs GOAT O1200 LiDAR Pro.

What reviewers found

Four home tests. T3 and Tom's Guide France tried the 800m² i208 in Europe, while Tom's Guide and The Daily Beast tested the US model, the i215. All four liked the quiet running and the neat cut, and none got the edges perfectly trimmed. They split on setup: Tom's Guide France had automatic mapping done in minutes, but T3 couldn't get it to work. Slopes split them too: The Daily Beast found its hill easy, while Tom's Guide saw the wheels spin and tear the grass.

Neat lines, very quietly

Once mapped, it mows in straight, overlapping lines after a few laps of the edge. T3 found the lawn looked tidier than when mowing by hand, and Tom's Guide France saw it change direction between runs so no tracks form. Noise is the other win. Tom's Guide France measured 45dB right beside it and 36dB three metres away, and The Daily Beast at first thought it wasn't running. T3 notes it leaves clippings on the lawn, so run it often.

Mapping: quick for some, fiddly for others

Tom's Guide France used automatic mapping on a simple garden and it was done in two laps, even with a fuzzy bamboo border. In a second, oddly shaped garden it drove the boundary by hand. T3 couldn't get automatic mapping to work at all, so it steered the mower round a small lawn instead, which took about ten minutes. Tom's Guide had to redraw one corner after the mower kept dipping its nose off it. Expect to tweak the map after the first few runs.

Good obstacle spotting, with gaps

T3 watched it slow down and steer round trees, furniture, planters and fences, though stray cables could still catch it. The Daily Beast saw it work round half-buried rocks. Tom's Guide France found it avoided objects, animals and people, but a low branch was sometimes read as an obstacle, and it brushed small shrubs closely. Tom's Guide had it avoid a small football and a toy, then run over a ball the size of a baseball. Its app doesn't mark where it met an obstacle.

Slopes and drops: mixed results

The Daily Beast has an uneven, mostly uphill garden and found the mower rocked briefly on bumps, then got through, and handled the hill easily. Tom's Guide saw a different side on its small sloping front lawn: the wheels sometimes spun on the steepest parts and tore up the grass. It also drove itself off a retaining wall once. Tom's Guide France's gardens were fairly flat, so it never got stuck. Map a margin around drops and walls.

Edges still need a strimmer

T3 found it gets close to the boundary but leaves a strip along the very edge. Tom's Guide France says an edge mode along walls helps without reaching the wall itself. Moving the map line so the mower overlaps a path worked better, though its route then wiggled a little. Tom's Guide wished it had a proper edge-mowing feature like some cheaper rivals. Plan on a quick trim every so often.

This page covers the i2 LiDAR sizes, not the i2 LiDAR Pro. T3 and Tom's Guide France tested the 800m² i208 LiDAR. Tom's Guide tested the US i215 LiDAR, and The Daily Beast tested the US model, where the i215 is the only size Navimow sells.

Before you buy

The questions people ask about this one

Does it need a boundary wire or an aerial?

Neither. It maps the garden with a laser scanner and camera, helped by satellite corrections sent over its built-in mobile connection, per the specifications. You either let it map automatically or drive the edge with the app. Tom's Guide France found automatic mapping quick, while T3 had to do it by hand.

Does it need a clear view of the sky?

Less than satellite-only mowers do. The laser lets it navigate under trees and at night, per the specifications. None of the four reviewers reported it losing its way near trees or buildings, and T3 saw it handle trees and fences without hesitating.

Will it cope with my slope?

It's rated for 45% (24°) inside the lawn and 25% at the edge, per the specifications. The Daily Beast found it handled an uphill garden with ease. Tom's Guide saw the wheels spin on the steepest bits of a small sloping lawn, tearing the grass, so steep patches may suffer.

How close does it cut to the edge?

Not all the way. T3 had a strip left along the edges, and Tom's Guide France found an edge mode along walls still left some grass. Moving the map line so it runs over a flush path helped Tom's Guide France get much closer.

Can it handle two separate lawns?

Only if they're joined. You can link zones with paths it drives along without mowing, per The Daily Beast. Tom's Guide France found that lawns with no route between them, such as front and back gardens, mean carrying the mower and running it without the map.

How noisy is it for neighbours?

Barely noticeable. Navimow quotes 59dB(A), per the specifications. Tom's Guide France measured 45dB right next to it and 36dB three metres away, and T3 could only hear a low, gentle buzz from its desk.

Segway Navimow

i2 AWD

Its sibling: the same app, with a driven third wheel that grips better on slopes and damp turns.

It relies on satellite positioning, so it needs open sky and can struggle beside buildings.
