# Best robot mowers for slopes and hills Source: https://mowandedge.co.uk/best/best-robot-mower-for-slopes 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 Slope ratings on robot mowers are given as a percentage, not in degrees, and the two are easy to confuse. A 35% slope rises 35 cm for every metre across and is only about 19 degrees. A 45% slope is about 24 degrees, and 84% is about 40 degrees. Measure your steepest stretch, not the average, and leave some headroom because wet grass reduces grip. This guide ranks robots by the slope limit their makers state, then compares the drive type, how they navigate, their rated lawn area and cutting width. If your garden has a bank that rises sharply from a patio, the top two or three picks are the ones to look at. For gentle slopes, any model here will do. ## 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. Husqvarna, Automower 315 (2018 model), grass area up to 1500 m², including anti-theft, 40% slope Navigation: Boundary wire; Rated area: 1,500 m²; Max slope: 40%; Cutting width: Not stated; Cutting height: 20 to 50 mm A proven boundary wire Automower for medium to large lawns, with app control through Automower Connect and a weather timer that adapts mowing to grass growth. In its favour: - Rated for lawns up to 1,500 m² and slopes up to 40%, a wide margin for most UK back gardens. - The listing mentions a weather timer that changes cutting time with growth, so it mows less in dry spells. - Anti-theft features are included, and Automower Connect lets you control it from your phone. Good to know: - This listing is for a 2018 model, so newer Automowers may add features it lacks. - The boundary wire has to be laid and pegged, which takes longer than an app-drawn map. ### 4.

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. ### 5.

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.
