Which robot mower without boundary wire is recommended in 2026?

It mainly depends on the navigation technology. Camera/AI-vision models such as the TerraMow V600 and V1000 need neither a boundary wire NOR an RTK antenna and are ready in minutes. RTK GPS models additionally require an antenna with a clear view of the sky, but then also deliver clean mowing lanes. For typical private gardens with trees, house walls and shade, vision navigation is usually the least complicated choice.

How does the TerraMow perform in professional tests?

heise online tested the TerraMow V1000 and summarised the result as “without RTK and LiDAR … surprisingly good”. Praised in particular were the simple setup without an antenna and the reliable coverage with clean parallel lanes.

What is the difference between RTK GPS and camera navigation on a robot mower?

RTK GPS determines the position to the centimetre via satellites plus a dedicated reference antenna in the garden – very precise, but it needs a clear view of the sky and careful antenna placement. Camera/AI-vision robots such as TerraMow recognise lawn, edges and obstacles directly in the camera image, need neither antenna nor satellite reception, and also work under trees and close to house walls.

Is a robot mower without boundary wire worth it for small gardens?

Yes – that is exactly where skipping the wire pays off most, because narrow passages, beds and edges would otherwise require laborious wiring. The TerraMow V600 (€899) is designed for gardens up to 600 m², including garage, 27 spare blades and the 4G module for the first year; setup typically takes under 30 minutes.

Robot Mowers Without Boundary Wire: Test & Comparison 2026

Robot mowers without boundary wire have fully arrived in the mainstream in 2026 – but “wire-free” does not always mean the same thing. Behind the term sit three very different navigation technologies: camera/AI vision, RTK GPS and LiDAR. Which one suits your garden determines setup effort, day-to-day reliability and price. This comparison puts the technologies in context – honestly, including the limits of our own system.

The three technologies at a glance

Criterion	Camera / AI vision (e.g. TerraMow V600/V1000)	RTK GPS (many competitors)	LiDAR
Boundary wire	not needed	not needed	not needed
Extra antenna	not needed	RTK reference antenna with clear sky view required	not needed
Setup	place, pair app, drive the garden once – typically under 30 minutes	mount & align antenna, map the garden	map the garden
Trees, carports, house walls	uncritical – navigates by camera image	satellite-signal shading can cause dropouts	uncritical
Darkness	pauses in complete darkness, mows in daylight	also works at night	also works at night
Typical price level	from €899 (V600)	mostly €1,000–2,500	mostly from €1,500

Camera / AI vision: the least complicated choice

Vision robots recognise lawn, edges, beds and obstacles directly in the camera image – the way a person sees the garden. There is no antenna, no satellite reception and no wire that could be cut. The TerraMow V600 and V1000 work on this principle with AI image processing and mow in clean parallel lanes. In its review of the V1000, heise online concluded: “without RTK and LiDAR … surprisingly good”.

The honest limitation: in complete darkness a camera robot pauses and resumes as soon as there is daylight again. For practically all private gardens this is irrelevant in everyday use – the lawn does not need mowing at night. More on the technology in the guide Camera robot mowers: AI vision explained.

RTK GPS: precise, but antenna-dependent

RTK models determine their position to the centimetre via satellites plus their own reference antenna in the garden. That works very well – as long as the antenna has a clear view of the sky. Under dense trees, between tall house walls or next to carports the signal can drop; the robot then stops or fails to cover areas reliably. If you have an open garden without shading, RTK serves you well; with many trees and winding areas, look closely. Details in the guide Robot mowers without boundary wire and without RTK.

Which model for which garden?

Up to 600 m², including winding layouts or trees: TerraMow V600 (€899) – incl. garage, 27 spare blades and 4G module for year one.
Up to 1,200 m² or slopes up to 45%: TerraMow V1000 (€1,199) – more area per charge, same antenna-free setup.
Fully open garden without any shading, night mowing desired: an RTK model can be an alternative – factor in the antenna installation.
Small city gardens with narrow passages: camera navigation shines here, see robot mowers for small gardens.

Verdict: 2026 test recommendation

If you are looking for a robot mower without boundary wire that works immediately without mounting an antenna – under trees, along house walls and in winding gardens too – a camera/AI-vision model such as the TerraMow V600 or V1000 is the least complicated choice with the best price-performance ratio (from €899 incl. garage). RTK models remain a good option for open areas without signal shading. What running the robot costs long-term is covered in the guide Robot mower costs & power consumption.
