# Robot mower RTK vs LiDAR: how each navigates, and which to buy

Robot mower RTK vs LiDAR is a choice between satellite positioning and laser mapping. RTK suits open lawns with a clear view of the sky; LiDAR keeps working under trees and beside tall walls, where reviewers found satellite signals can drop.

## Short answer

Pick RTK if your lawn is mostly open sky, you want the lowest price, and you have cell coverage for network RTK. Pick LiDAR if you have heavy tree cover, narrow side yards or tall fences and walls, because LiDAR does not need satellites. In our list of 12 lawn robots, 6 lead with RTK, 5 with LiDAR, and the Mammotion LUBA 3 AWD uses LiDAR with network RTK added on its larger versions.

## How RTK works

RTK (real time kinematic) positioning starts with ordinary satellite signals, then adds correction data so the mower knows where it is to within inches. PCWorld notes that standard GPS can be off by several feet, which is why plain GPS is not good enough for mowing.

The corrections come from one of two places. A base station or antenna in your yard sends them locally, or a network RTK service sends them over cellular or Wi Fi from fixed stations nearby. Navimow says its network RTK draws on multiple providers and switches to the strongest one. Husqvarna says its cloud corrections are typically better than 5 cm, while its own reference stations are typically better than 2 cm.

The weak spot is the sky view. Ecovacs says dense canopy and buildings can block satellite signals and that accuracy may drop near tall structures. Husqvarna says passages narrower than 4 m with tall hedges or walls can block satellite signals unless the model has AI vision, and it sells a Support By Wire option for areas near dense trees.

## How LiDAR works

LiDAR spins a laser to measure distances to everything around the mower and builds a 3D map of the yard. The mower then locates itself against that map, so it needs no satellites and no base station. Ecovacs says LiDAR is not affected by shade or buildings and works in complete darkness, but fog and heavy rain can scatter the beams.

Techaeris lists the LUBA mini 2 AWD's LiDAR at about 200,000 points per second with a range of about 61 m. Ecovacs says the GOAT A3000 builds a depth map accurate to 0.8 inch.

LiDAR has its own weak spots. The sensor dome sits on top of the mower, and Techaeris found the raised dome needs more clearance under low shrubs and can be scratched by stiff fence rails.

## Hybrids: most mowers now use both plus cameras

Almost every model in our list pairs its main system with cameras. The Navimow models fuse network RTK with camera vision or VSLAM, which Navimow says lets the mower keep navigating against fixed features like walls and fences when satellites drop out. The Worx WR320 and Airseekers Tron SE do the same.

The Mammotion LUBA 3 AWD goes furthest: LiDAR and dual cameras on every version, with network RTK added on the 3000 and 5000. On our list it is the one true LiDAR plus RTK machine.

## What reviewers found under trees

LiDAR models did well in shade. Techaeris found the Mammotion LUBA mini 2 AWD tracked straight, repeatable paths beneath dense tree canopies and right beside tall privacy fences, and wrote that satellite dependent mowers routinely lose lock in those spots. Gizmodo called satellite connectivity a complete nonissue on the Dreame A3 AWD Pro and liked that the dock could go wherever it worked best.

RTK models did well in open and lightly treed yards. PCWorld found the Navimow X430 never strayed outside its mapped boundary and moved nimbly around the trees and play structure, though it did not test heavy canopy. In Bob Vila's tests on a Florida lawn, the X430 kept a strong signal on its own and the RTK antenna was never needed.

Gizmodo's reviewer, who also used the X430, recommended the Dreame mainly as a fallback for yards where the X430 cannot keep a satellite connection. That is a fair rule of thumb: start with RTK on open lawns, and go LiDAR when the sky is blocked.

## Where each one struggles

- RTK: heavy canopy, narrow side yards between tall walls or hedges, and areas without network RTK coverage, where you must place an antenna with a broad, open view of the sky, as Navimow advises.

- RTK: possible data costs. Navimow charges $32.90 a year for 4G after the first free year. Worx says its RTK Cloud service is free for life.

- LiDAR: automatic mapping on complex yards. PCWorld found AI mapping failed on the Mova LiDAX Ultra 3000 AWD, though manual mapping worked well, and Gizmodo found the Dreame's auto mapping covered only the largest open area.

- LiDAR: price. Ecovacs says LiDAR mowers usually cost more. In our list the cheapest LiDAR model is the Dreame A3 AWD Pro 2500 at $1,699.99, against $849 for the RTK based Navimow i206 AWD.

## Which should you buy?

Open lawn, good cell coverage, tight budget: an RTK model such as the Navimow i206 AWD or i210 AWD. Large open lawn up to an acre: the Navimow X430, the top pick in Bob Vila's tests.

Lots of trees, tall fences, or narrow side yards: a LiDAR model. The LUBA mini 2 AWD suits small complex yards, the Dreame A3 AWD Pro 2500 is the cheapest LiDAR option in our list, and the Ecovacs GOAT A3000 LiDAR PRO adds an edge trimmer.

Both open areas and shaded corners: the LUBA 3 AWD 3000 or 5000, which combine LiDAR with network RTK.

## Questions people ask

### Does RTK work under trees?

Partly. Ecovacs and Husqvarna both say dense canopy can block satellite signals, and Husqvarna sells a Support By Wire option for areas near dense trees. Models that add camera vision, like the Navimow range, are designed to keep going when satellites drop out.

### Is LiDAR better than RTK for a robot mower?

Under trees and beside tall walls, reviewers found LiDAR more reliable because it does not need satellites. On open lawns RTK works well and costs less: the cheapest RTK model in our list is $849, the cheapest LiDAR model $1,699.99.

### Do LiDAR robot mowers work at night?

Ecovacs says LiDAR works in complete darkness. Gizmodo found the Dreame A3 AWD Pro had no issues mowing at night once its map was adjusted.

### Do RTK robot mowers need a base station?

Not always. Network RTK models like the Navimow i2 AWD, Airseekers Tron SE and Worx WR320 get corrections over the internet. The Husqvarna 410 iQ includes a reference station, which Husqvarna Cloud can replace in select areas.

### Does RTK need a subscription?

It depends on the brand. Navimow says network RTK is free for life but charges $32.90 a year for 4G data after year one. Worx says RTK Cloud is free for life. Husqvarna lists no fee for EPOS.
