Gardena smart SILENO free — 1,200 m²

The smart SILENO free 1200 m² by Gardena is a wire-free robotic mower for large lawns, with a maximum slope of 30% and a sound level of 58 dB(A). Its GPS RTK navigation locates the mower precisely across the garden, backed by SensorControl, which automatically adjusts mowing frequency to grass growth throughout the whole mowing season, without any manual reprogramming needed.

With no wire to bury, the mower positions itself by satellite and builds its map from landmarks added in the app as it mows. Around a tree, root or slope over 25%, an exclusion zone is set by driving the mower around the perimeter to protect. Contact with an obstacle triggers Trim-to-Edge mode, which mows as close as possible using a dedicated border-cutting disc.

It connects via Bluetooth and Wi-Fi through the Gardena app, with built-in anti-theft geolocation to track its position at all times, even outside the garden. Its 18V, 5 Ah lithium-ion battery powers a 22 cm cutting width, height-adjustable from 2.5 to 4.5 cm, for an average mowing time of 140 minutes despite the large surface to cover. Rated IPX5 and weighing 10.8 kg, this Gardena robotic lawn mower is built for large, wire-free gardens.
