GARDENA Smart Sileno city 250m2

The smart Robotic Lawnmower for gardens up to 250 m²

Lawn care can be so easy and effortless! With its SensorCut Systems, the Gardena smart SILENO city mows your lawn accurately and reliably and is so quiet, you can hardly hear it. When it has finished, it automatically returns to the charging station. You can enjoy your free time and a perfectly manicured lawn. The smart SILENO city is suitable for lawn areas of up to 250 square metres. It masters inclines of up to 35 percent. During installation, a programming assistant guides you through the menu and independently calculates the mowing plan. The mowing times can also be set via smart App and aligned with the irrigation times of the smart Water Control. The smart Gateway ensures central networking, which creates an internet connection using an existing router. In this way, it acts as the core of the smart system to permit cable-free network communications between all Gardena smart system devices in the garden and the Gardena smart App.

Everything Under Control

Using the free Gardena smart App for iOS, Android and Web, you always have your garden under control, wherever your location. By tapping the screen, you can call up the important information required and adapt all settings for your garden work conveniently and according to requirements.

Perfectly manicured lawn

The precision blades cut the grass cleanly. And thanks to the SensorCut System, the Gardena smart SILENO city does not cause lawn stripes. The cutting-height adjustment can be carried out easily and without the use of tools.

Effortless enjoyment

Put up your feet and enjoy your garden! Your Robotic Lawnmower will deal with the lawn-cutting side of things. The fine cuttings remain on the lawn as a natural fertiliser. This promotes good growth and saves valuable time in which you can dedicate yourself to other things.

Easy installation

A programming assistant guides you through the intuitive menu and, following entry of the lawn size and preferred mowing times, independently calculates the mowing plan according to which the smart SILENO city operates. Complex calculations and programming are not required. The mowing plan can be slightly modified or adjusted when necessary.

Easy cleaning guaranteed

The Gardena smart SILENO city has been constructed so that simple spraying with the garden hose thoroughly frees housing, blades and wheels of dirt, dust and residual grass.

Maximum safety

The boundary wire determines the mowing area flexibly and yet reliably – ensuring that the Robotic Lawnmower only mows the areas specified. A highly sensitive collision sensor ensures that the Robotic Lawnmower is not bothered by garden obstacles. When the tool is lifted, the blades stop immediately, thus preventing injuries.


A PIN code ensures theft protection security.

Secure Connection

The smart Gateway enables cable-free network communications between all Gardena smart system devices and the Gardena smart App. The stable and secure connection takes place using especially powerful radio technology. Two integrated high-performance antennas ensure a stable and secure connection even over extensive ranges.
