Mulching functionSmall grass clippings left behind by the mower, provide shade that supports moisture retention and protection from the sun. These clippings also turn into fertilizer that enriches the soil with nutrients. |

Boundary & guidingThanks to guide cable, it navigates reliably through all lawn areas and back to the charging station via the shortest route. Use the boundary wire to specify exactly where the mower should go, enabling you to stay in control and keep your mower safe. Built-in sensors also ensure that the mower blades stop immediately once picked up. |
All weather and terrainCapable of mowing the lawn, come rain or shine, SILENO doesn't need a rain sensor to do its job. Stay cozy and dry while your robot does the work for you. Complex lawns with grassy slopes up to 35 percent (19°) are no match for this mower. |
AI-precise & Spot Cutting functionPatented guiding technology prevents the mower from using the same path to enter it's base station, thus preventing tracks in your lawn. With AI-precise cutting patterns, tight corners and passages as narrow as 24 inches are cut reliably. The Spot Cutting feature takes care of hard-to-reach grassy areas underneath trampolines or garden furniture. |
Bluetooth connectionTo Easily control your Sileno with your smartphone, Download the GARDENA Bluetooth app on your mobile device. Turn off the Mower and turn it on again. Pair the GARDENA Bluetooth app with the product and enter the PIN code. NOTE: The Bluetooth pairing mode is active for 3 minutes. The app is used for settings and operation of the mower but can be operated using the control panel on the mower itself. |
