Does the eufy E15 need a boundary wire or an RTK aerial?

No. The eufy Robot Lawn Mower E15 needs neither a perimeter wire nor an RTK reference station. It finds its way with a pair of cameras, which eufy calls V-FSD, and uses image recognition to tell lawn apart from paths, borders and obstacles. The only fixed hardware is the charging base, and eufy includes a garage for it in the UK box.

There is a satellite receiver inside, but eufy says it is there for anti-theft tracking over 4G, not for steering. That means tall hedges, trees and the side of the house don't cause the signal problems they can for RTK mowers.

Camera navigation has its own rules. eufy asks owners to clear, or mark as no-go zones, anything under about 5 cm tall or smaller than 10 × 10 cm, such as hoses and small toys. It also needs light to see, so it isn't one for night-time schedules (which you'd want to avoid anyway for hedgehogs).

Set-up happens in the eufy app, which builds the map and lets you edit zones and no-go areas afterwards. The E15 is rated for 800 m² and slopes up to 32.5%, so check both numbers against your lawn. Our navigation guide explains how camera, RTK and LiDAR systems compare.
