The Segway Navimow i215 LiDAR is a mid-priced mower built for the shady suburban yard. It navigates with LiDAR and a camera instead of satellites, so trees, fences and the side of your house don’t throw it off. Setup is among the easiest in the category. The catch is underneath: it’s a two-wheel-drive mower, and reviewers consistently found that slopes, wet ground and drop-offs expose that.

Who the Navimow i215 is for (and who should skip it)

The i215 suits lawns of a quarter to a third of an acre (up to about 16,100 sq ft) with trees, multiple sections or narrow passages. PCWorld’s reviewer recommended it for “lawns with some complexity,” and that’s the right way to think about it. If your RTK mower keeps losing position under a maple, or your neighbor’s has, this is the fix.

Skip it if your yard is hilly. Rear-wheel drive and a 45% rating mean steep or side-sloped lawns are better served by an AWD mower. Skip it if your lawn is open and flat, too, because cheaper RTK mowers do that job for less. And if you want edges trimmed automatically, a GOAT with a built-in trimmer is a better fit.

Navigation and setup

This is the i215’s best feature. There’s no perimeter wire and no antenna on a pole. You place the dock, connect to Wi-Fi, update firmware (about 20 minutes, per PCWorld) and map. In auto mode, you steer the mower onto the grass and it traces the boundary itself, staying “about 11.8 to 19.7 inches inside the lawn’s edge,” according to PCWorld, before tidying the boundary. AndroidGuys notes auto-mapping works best in clearly defined spaces. In open yards without obvious borders, you’ll drive the boundary yourself with the app’s joystick.

LiDAR keeps working in the places RTK hates. AndroidGuys found it handled fence lines, the sides of the house, ground beneath trees and passages around 70 cm (about 28”) wide. Our navigation explainer covers why LiDAR has the edge under canopy.

The weak spot is drop-offs. PCWorld saw it slip off the grass near a narrow fence edge “a couple of times,” noting it lacks dedicated cliff sensors. Tom’s Guide’s Mike Prospero had it nose-dive off one corner of his lawn and drive off a retaining wall before he redrew the map a few inches inward. The fix is easy, but plan to watch the first few runs and add buffers near any ledge.

Mowing performance, slopes and terrain

Navimow’s EU spec rates the i215 for 45% slopes (about 24°), and one secondary source lists 30%. Either way, treat it as a mower for gentle terrain. AndroidGuys found it struggles on side slopes and in wet conditions, and listed deep ruts, exposed roots, leaf piles and mud as trouble spots. Tom’s Guide saw it spin its wheels on the steepest part of a small, sloped front yard, which “tore up the grass a bit.” Its mowing plan helped by cutting diagonally rather than straight up the hill.

All slope ratings assume dry, short grass, so measure with the slope checker before you buy.

Obstacle avoidance is good but not perfect. Tom’s Guide watched it steer around a small soccer ball and a plastic toy but run over a baseball-sized ball. Unlike some rivals, the app doesn’t mark where it found an obstruction. You only see an unmowed patch on the map.

Coverage, cutting and edges

The 8.7” deck is wider than most small-yard mowers (7”–7.9”), which helps on a third of an acre. Cut quality gets good marks: PCWorld reported “a clean, even cut across the mapped area” once the map was dialed in. Height adjusts from 0.8” to 2.8” in the app, which is handy, though that top setting is low if you keep cool-season grass long in summer.

Edges are a partial win. EdgeSense handles flat borders like paths and patios. Along fences and walls, AndroidGuys found “a narrow uncut strip remains and will need periodic attention from a string trimmer.” Tom’s Guide also wished for pattern mowing, which the Navimow app doesn’t offer.

App, connectivity and anti-theft

The Navimow app shows live position, coverage percentage and battery, and lets you set schedules, cutting height, zones and Precision or Efficient modes. Anti-theft is strong for the price. Tom’s Guide reports a geofence alarm adjustable from about 33 to 164 feet plus Apple Find My support. It also works with Alexa and Google Assistant. The first year of 4G Connect+ is free, then $32.90 a year per PCWorld. Our theft protection guide has more on securing a mower.

Ownership notes

• Running costs: about $33 a year for 4G after year one, plus blades.
• Map tuning: budget an hour or two of edits after the first runs, especially near drop-offs and retaining walls.
• Weather: Navimow doesn’t publish an IP rating for the US model, so a garage or covered dock is worth considering.
• Price: mid-range tier, but PCWorld found it below list at several retailers, and Tom’s Guide saw it lower still on Amazon. Prices move often, so check today’s price.

How the Navimow i215 compares

The Sunseeker S4 is the closest rival: also LiDAR, also 2WD, a little smaller at 0.25 acre and often cheaper. Tom’s Guide preferred the S4’s object reporting and pattern mowing. The Dreame A3 AWD adds all-wheel drive and an 80% slope rating to LiDAR navigation for a similar sale price, which makes it the better buy for shady and sloped yards. If your small yard is sloped but open, the Navimow i2 AWD costs less. Our guides to the best robot mowers for complex yards and best mowers for small yards compare these head to head.

Bottom line

The Navimow i215 LiDAR is one of the easiest mowers to live with in a shaded, awkward, medium-sized yard. It sees under trees, sets itself up and cuts cleanly. Pair it with a gentle lawn, add buffers near any drop-off, and keep a trimmer for fence lines. If your yard has hills too, spend the same money on AWD.
