Best robot mowers without a perimeter wire

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.

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.

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.

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.

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.

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.

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.
