With its pioneering LONA technology (LOCALISATION & NAVIGATION), the intelligent SILENO life, 400m² offers many possibilities through the GARDENA smart app for the unique configuration of the robotic lawnmower and the real-time monitoring of all its movements. The robotic lawnmower now knows exactly where it is. Thanks to LONA, you can map the entire garden, create a map and use it for mowing activities. This map is displayed in the GARDENA smart system application, so the owner can make many additional settings. For example, shady areas where grass grows more slowly can be mowed less frequently or even omitted altogether. The Zone Management function allows you to flexibly define which areas should be mowed, when and how often. With Area Protect, you can even define areas that the mower must not enter at all, for example to protect a wildflower meadow. The advanced CorridorCut function guides the robotic lawnmower as it easily cuts the grass in tight corners and in passages of up to 60 cm between boundary wires.

CorridorCut even navigates the robotic lawnmower out of complicated cul-de-sacs. The innovative Spot-Cutting function, a spiral cutting mode, allows the intelligent SILENO city to work in other hard-to-reach areas. All other intelligent irrigation systems can also be controlled via the app. The app is free to download for smartphones, tablets and PCs; there are no subscription fees. The GARDENA SILENO city cuts the blades of grass precisely and independently to the right length. It's so quiet you can hardly hear it mowing the lawn and then automatically returns to its charging station. GARDENA SILENO city is suitable for lawns of up to 400 square meters and copes with uneven terrain and slopes of up to 35%. The extremely impact-resistant plastic housing makes the GARDENA SILENO city particularly robust. Even the bad summer weather doesn't bother him. Thanks to its reliable operation, it works regardless of the weather, even in the rain. The intelligent gateway ensures the central network connection. It can be discreetly placed in the living space and establish an Internet connection through an existing router. As the heart of the intelligent system, it manages the wireless network communication between all GARDENA intelligent system devices in the garden and the GARDENA smart app. Two integrated high-performance antennas ensure a stable and secure connection, even over long distances.
