Check Your Lawn First: Ensure your lawn is under 800 m² (max mapping area), is mostly flat with variations under 3 centimetres (3.5 inches), and any slopes are less than 40% (18°). Note: Not suitable for St. Augustine and dense Zoysia grass. Wire-Free with a Stable Signal: Pure vision FSD technology with high-precision cameras and intelligent AI algorithms enable accurate mapping and obstacle avoidance via Wi-Fi or 4G with no need for boundary wires or an RTK station. Hands-Free Auto-Mapping: With precise positioning and distance measurement, E15 accurately maps your garden and optimises its mowing path for maximum efficiency. Use the eufy app to keep track of everything and customise your lawn care. (Note: Subscribe to 4G data via the app for stable connectivity if your garden isn't fully covered by Wi-Fi.) Accurate Obstacle Avoidance: Cutting-edge 3D perception system accurately detects obstacles, avoiding collisions in even the most complex of gardens. Complete Coverage: Smart coverage detection system and Ride-on-Edge technology deliver an even cut and mowing that goes right to the edges of your garden. Safety First: 4G-enabled GPS tracking means you always know where your mower is for greater peace of mind, while automatic recall during rainy or low-light conditions ensures E15 only mows when it's safe.
