Robotic lawn mower Gardena smart SILENO free Maximum lawn area 1200 m² Cutting width 16 cm

The Gardena smart SILENO free is a battery-powered robotic lawn mower designed for lawns up to 1200 m². It delivers automated grass cutting with a 16 cm cutting width and uses Gardena’s LONA navigation system to plan efficient mowing paths. The mower’s compact footprint (630 mm width, 430 mm depth, 260 mm height) allows it to operate in varied garden layouts, and the included 150 m boundary wire helps define mowing zones during installation.

Advantages

The Gardena smart SILENO free offers autonomous lawn maintenance with quiet operation and consistent cutting performance. LONA navigation optimises coverage to reduce missed spots and overlaps, while the narrow 16 cm cutting width enables precise trimming near edges and obstacles. Its compact dimensions facilitate movement through tight areas and storage when not in use. Battery operation eliminates the need for fuel or trailing cables.

• Private lawns and medium-sized gardens up to 1200 m²

How to use

Install the boundary wire according to the layout of the lawn to mark the mowing area and any no-go zones, ensuring the wire is secured at the recommended spacing from borders and obstacles. Charge the mower’s battery before the first use and place the charging station on a level surface with access to the defined perimeter. Program mowing schedules via the control interface or compatible app, allow the mower to perform an initial mapping run using LONA navigation, and monitor the first mowing cycles to confirm complete coverage. Regularly empty grass clippings if needed, check the blade condition, and maintain battery charge for consistent operation.

Usage recommendations

The mower performs best on regularly maintained lawns with moderately even terrain. Keep the boundary wire clear of debris, trim excessively long grass before first runs, and perform seasonal maintenance such as blade inspection and battery care to sustain optimal performance.
