Two 2026 releases are worth a look if you’ve been holding off on a robot mower: Segway’s Navimow i215 LiDAR, which needs no antenna or base station in your yard, and Roborock’s RockMow X120H LiDAR, the robot-vacuum maker’s all-wheel-drive mower for US lawns. Both are sold in the US through the brands’ own stores and on Amazon. If you’re still working out what size or type of mower your yard needs, start with our robot mower buying guide by yard size. This page covers what’s new.
Navimow i215 LiDAR: Wire-Free Without a Base Station
Segway’s Navimow i215 LiDAR pairs a solid-state LiDAR with onboard cameras for what the company calls Dual Fusion navigation. The headline feature is that it needs no local antenna or base station where network RTK coverage is available: it takes its position correction over included cellular data, so setup is mapping your yard through the Navimow app. It’s rated for yards up to 0.37 acre, which puts it above Segway’s i105N (1/8 acre) and i210 AWD (1/4 acre).
| Segway Navimow i215 LiDAR | Spec |
|---|---|
| Coverage | Up to 0.37 acre |
| Navigation | LiDAR + vision Dual Fusion, network RTK included, no base station |
| Slope handling | Up to 45% (about 24°), off-road wheels + Electronic Stability Control |
| Cutting | 8.6 in (22 cm) width, 6 blades; 2–4 in height (per the Amazon listing) |
| Battery / runtime | 7.65Ah, about 130-minute charge, up to 160 minutes of runtime |
| Obstacle detection | 200+ obstacle types, 0.4 in accuracy |
| Noise | 59 dB(A) |
| Price | $1,599 list at Navimow’s US store; seen on sale around $1,399 in July 2026 |
What a hands-on review found: PCWorld tested the i215 on a 0.18-acre area with slopes, trees and shade and reported a clean, even cut and easy wire-free setup, but noted it has no dedicated cliff sensor and slipped off a narrow edge into a drop-off once. Budget for the Navimow Connect+ subscription too: PCWorld lists it at $32.90 a year after the first year, while Segway says network RTK access and its cellular data are included at no extra cost.
Roborock RockMow X120H LiDAR: 4WD for Rough, Sloped Lawns
Roborock is best known for robot vacuums, and the X120H LiDAR brings the same idea of fusing LiDAR with camera vision to the lawn. It’s built for tougher yards than the i215: four-wheel drive with active steering and suspension, an 80% slope rating and 3.1-inch obstacle clearance.
| Roborock RockMow X120H LiDAR | Spec |
|---|---|
| Coverage | 1/2 acre recommended (Amazon lists up to 0.49 acre) |
| Navigation | Vision-LiDAR fusion, AI mapping, no perimeter wire |
| Drive | 4WD with active steering and dynamic suspension |
| Slope / obstacles | Up to 80% (39°); obstacles up to 3.1 in |
| Cutting | 9.4 in width, 6 blades, 1.6–3.5 in height (electric adjustment); edge-cutting add-on optional |
| Battery / runtime | 6Ah, 110 minutes per charge, 50-minute recharge |
| Weight / rating | 47.8 lb, IPX6 |
| Price | $2,299 at Roborock’s US store (September 2026) |
Amazon showed the X120H LiDAR as temporarily out of stock when we checked, so compare with Roborock’s own US store before you buy.

If your lawn falls between a quarter and a third of an acre, compare the i215 LiDAR with the models in our LUBA 3 AWD vs Navimow i210 AWD comparison. For a smaller lawn, see Segway’s Navimow i105N, and for how LiDAR, RTK and network RTK differ, our wire-free mower explainer.
Should You Buy Now, or Wait?
The i215 LiDAR is an incremental update from a brand with a track record in wire-free mowers, so its no-base-station convenience is a lower-risk upgrade if a yard under about 0.4 acre fits your needs. The X120H LiDAR is newer to US lawns: Roborock has the scale and app experience to compete, but we’d want to see more US owner reviews before recommending it over an established option like the LUBA 3 AWD at a similar price. If your yard is steep or rough, it’s worth a look; if it’s gentle and under a third of an acre, the i215 costs less.
