Our verdict
The Mammotion LUBA 3 AWD 3000 needs nothing installed but its charging station and handles trees, open lawns and 80% slopes. The Navimow X430 is the pick for big open lawns, the LUBA mini 2 AWD for small shaded yards, and the Navimow i206 AWD for the lowest price.
A boundary wire is the oldest way to fence in a robot mower: you peg or bury a cable around every edge and flower bed, and repair it when it gets cut. Every mower on this list skips that. They set the boundary from a map you draw in the app, and find their way with LiDAR, satellite RTK or cameras. We ranked them on published specs, independent reviews and owner reports; see how we research.
What "wire-free" can still mean
| Approach | What you install | Weak spot |
|---|---|---|
| Network RTK + cameras (Navimow) | Nothing but the station | Heavy tree cover |
| LiDAR + cameras (LUBA mini 2, Dreame A3, Ecovacs GOAT) | Nothing but the station | Hot weather on some LiDAR units (owner reports) |
| Cameras only (eufy E15) | Nothing but the station | Low light, bumps and damp grass |
| LiDAR + network RTK + cameras (LUBA 3 3000/5000) | Nothing but the station | Price |
| EPOS RTK with reference station (Husqvarna iQ) | Station plus reference station with its own outlet | Open sky needed |
Our RTK vs LiDAR vs camera comparison explains each in plain terms.
How to choose
- Open lawn, few trees: network RTK works well and is often cheaper; the Navimow X430 or i206 AWD.
- Trees, sheds and walls: choose LiDAR; the LUBA mini 2 AWD, LUBA 3 AWD or Navimow i215 LiDAR.
- Steep banks: look for all-wheel drive; every Mammotion LUBA, the Navimow X4 and the Dreame A3 AWD are rated for 80% or more.
