## Long description

GARDENA smart SILENO max is a robotic lawn mower engineered for automated maintenance of lawns up to 1500 m². Designed for medium to large residential green areas, it features a 16 cm cutting width, battery power and LONA navigation to plan efficient routes. The compact housing with dimensions 630 × 430 × 260 mm and the inclusion of an edge-cutting function enable consistent, regular mowing while minimising manual intervention. The mower supports installation with up to 150 m of boundary wire for defining work zones and uses tilt sensing for safety during operation.
Advantages
The robot provides consistent cutting performance across varied lawn shapes thanks to LONA navigation and a 16 cm cutting width. Battery operation removes the need for fuel and reduces on-site noise compared with combustion equipment. Edge-cutting capability helps achieve a neat lawn border without separate finishing passes. Tilt sensor and boundary wire compatibility improve operational safety and keep mowing within defined areas.

How to use
Install the boundary wire to define the mowing area and any internal islands, following the manufacturer's layout recommendations. Charge the battery fully before the first use and place the charging station on a level surface within reach of the boundary wire. Configure mowing schedules and working preferences via the control interface or compatible app if available, then start the robot to begin automated mowing cycles. Periodically inspect cutting blades, remove accumulated grass clippings, and check the boundary wire and charging contacts to maintain reliable performance.
Usage recommendations
For best results, prepare the lawn by removing loose objects and repairing uneven patches. Maintain a regular schedule to avoid overgrowth and inspect blades every few weeks for wear. Use the edge cutting feature to keep perimeter areas neat and ensure the boundary wire is installed securely to prevent accidental crossings.
