Product details
The smartSileno sense 400 robot lawnmower from Gardena offers an innovative solution for lawn care in gardens up to 400 m². With its wireless technology, it enables simple installation without a boundary wire, making it particularly easy to use. The integrated SIM card ensures permanent, free mobile connectivity so that the robot lawnmower is always ready for use. Thanks to the advanced trim-to-edge function and camera-supported AI, the robot lawnmower automatically recognises edges and ensures a precise mowing result. Satellite-based navigation enables it to define a virtual boundary, while object recognition ensures that it reliably avoids obstacles. In addition, all camera recordings remain stored on the device, which guarantees data protection. The smartSileno sense 400 is therefore an efficient and safe choice for modern lawn care.
- Wireless installation without boundary wire
- Trim-to-edge function for precise mowing along edges
- Integrated object detection for safe avoidance of obstacles
- Data remains stored exclusively on the device, no external access.
