# Best robot mowers without a perimeter wire Source: https://mowandedge.co.uk/best/best-wire-free-robot-mower Publisher: Mow and Edge. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://mowandedge.co.uk/how-we-pick A wire-free robot mower replaces the pegged boundary wire with a map. How it builds and follows that map is what separates one model from another. RTK models use satellite positioning corrected by a reference signal, which is very accurate in open lawns but can drift beside tall walls and under dense trees. Vision models use cameras to recognise the lawn edge, and lidar models scan the garden with lasers, which works in shade but needs clear landmarks. Many robots now combine two or more. This guide compares wire-free models on how they navigate, whether an antenna has to be mounted, rated lawn area, slope limit and the narrowest passage the maker quotes, using only the facts in each listing. ## Products ### 1. ECOVACS Goat O1000 RTK Robot Lawn Mower, Perimeter Wire Free Vision Robotic Lawnmower for 1/4 Acres Lawn, Automated Mapping, APP Control, 3D Obstacle Avoidance, Zero-Edge Cutting Navigation: RTK + lidar + camera, no wire; Rated area: About 1,000 m² (1/4 acre); Max slope: 45%; Cutting width: 22 cm; Cutting height: 30 to 80 mm A wire-free robot that maps the lawn itself using RTK positioning backed by a 3D ToF sensor and a fisheye camera. Suits a typical suburban lawn with trees and borders. In its favour: - The listing states an IPX6 rating and 2 cm positioning precision, with a camera and lidar to help under tree shade. - TruEdge edge mowing follows borders closely, which the maker says cuts down on strimming afterwards. - Climbs slopes up to 45% and fits through passages about 70 cm (2.3 ft) wide, according to the listing. Good to know: - The listing uses US units and US style wording, so check the charger plug and UK support before ordering. - It does not state noise level or run time per charge beyond a 60 minute battery figure. ### 2. MAMMOTION YUKA 1500 Robot Lawn Mower, up to 1500m², 3D Vision and RTK, 45% Slope, Peripheral Wireless Installation, Multi-Zone Management and Prohibited Zone, Anti-theft Navigation: RTK + 3D vision, no wire; Rated area: 1,500 m²; Max slope: 45%; Cutting width: 32 cm; Cutting height: 20 to 90 mm A wire-free robot with a wide 32 cm cut and a collector that sweeps leaves and clippings, then empties itself at a set spot. Suits larger lawns with trees. In its favour: - A 320 mm dual disc cut is wider than most robots here, so it covers ground quickly. - The maker says it can sweep leaves and small twigs and empty itself, useful in a UK autumn. - Up to 10 mowing zones with passages and no-go areas can be set in the app. Good to know: - At 15.6 kg and 64 x 52 cm it needs wider passages than slim robots. - The listing does not say whether an RTK antenna has to be installed, so check setup needs with Mammotion. ### 3. Worx Landroid Vision Cloud 4WD Robot Lawn Mower, No Perimeter Wire Robot Mower for 1/2 Acre, AI Obstacle Avoidance + RTK Cloud Navigation, 84% Slope, Auto Mapping, App Control, Cut-to-Zero, WR342 Navigation: RTK Cloud + vision, no wire; Rated area: About 2,000 m² (1/2 acre); Max slope: 84%; Cutting width: 22 cm; Cutting height: 40 to 90 mm A four wheel drive wire-free Landroid using RTK from the cloud with no local antenna, built for steep and uneven gardens up to about half an acre. In its favour: - Rated for slopes up to 84% (about 40 degrees), far beyond typical two wheel drive robots. - RTK Cloud means no antenna to mount, and the maker says camera navigation takes over in shade. - Find My Landroid GPS tracking with remote lock is included, according to the listing. Good to know: - At 29 kg it is heavy to lift over steps or carry to storage for winter. - The lowest cutting height is about 40 mm, higher than some robots, so it suits relaxed rather than very short lawns. ### 4. ECOVACS Goat O1000 LiDAR PRO Robot Lawn Mower, Wire-Free Mapping with LiDAR Navigation, AI Obstacle Avoidance, Smart Edge Mowing, App Control, for Lawns Up to 1/4 Acre Rated area: About 1,000 m² (1/4 acre); Boundary: Wire-free (lidar); Cutting width: 22 cm; Noise: Not stated A slim wire-free lidar robot that the maker says fits through 0.8 m corridors. A good pick for small but complicated plots with shade. In its favour: - Super-narrow body passes through corridors as slim as 0.8 m. - No wire and no RTK antenna, according to the listing. - Built-in edge trimmer reduces manual strimming. Good to know: - Rated area is far beyond a small lawn, so you pay for capacity you may not use. - No noise figure is stated in the listing, unlike the Gardena models. ### 5. Bosch Cordless Robot Lawn Mower VISIMOW18V-100 (For Lawns up to 100 m², Cutting Width: 16 cm, Height of Cut: 20-60 mm,without Battery) Rated area: 100 m²; Boundary: Wire-free (vision); Cutting width: 16 cm; Noise: Not stated A wire-free camera robot for lawns up to 100 m², ideal for a small front lawn or a few small patches.

In its favour: - No boundary wire or base to install, according to Bosch. - Handles multiple small lawns and zones up to 100 m² in total. - Cutting height adjusts from 20 to 60 mm. Good to know: - Battery not included, so budget for one if you do not own the platform. - Too small for a lawn much over 100 m², as that is its rated maximum. ### 6. Robot Husqvarna Auto Motor 430 V Black Max slope: 50%; Drive: Not stated; Navigation: Virtual boundary, no wire; Rated area: Not clearly stated; Cutting width: Not stated A Husqvarna wire-free Automower with a virtual perimeter and a stated 50% maximum slope, for larger and steeper lawns where dealer backing matters. In its favour: - The listing gives a 50% maximum slope inside the working area. - Uses a virtual perimeter, so there is no boundary wire to lay or repair. - Husqvarna lists spare part availability for five years. Good to know: - The listing area figure looks wrong, so confirm the rated area with Husqvarna or a dealer. - Very few specs are given, including cutting width and height. ### 7. Dreame A2 Robotic Lawnmower Navigation: OmniSense 2.0 3D detection; Antenna needed: Not stated; Rated area: Not stated; Max slope: Not stated; Narrowest passage: Not stated A wire-free Dreame robot with OmniSense 2.0 3D detection, AI-assisted boundaries and EdgeMaster edge driving.

In its favour: - AI-assisted boundary setup means no wire to lay, according to the listing. - EdgeMaster is designed for precise driving along lawn edges. - The app supports dual maps, cut modes and separate areas. Good to know: - The listing gives no rated area, slope or cutting width, so check Dreame's own spec sheet. - Little detail on obstacle handling beyond the headline feature.
