Gardena Sileno Life 1250 m² Robotic Lawnmowers - Grey & Turquoise | 15103-28


The powerful robotic lawnmower for lawns up to 1250m²

The SILENO Life robotic lawn mower from GARDENA is designed for more complex lawns. The SILENO robotic mower is unrivalled when it comes to noise; at just 58 dB (A) you won’t have to worry about disturbing the neighbours!

The base station can be installed almost anywhere in your garden. It is also all weather proof and will mow come rain or shine, up or downhill. Even on slopes of up to 35%, the SILENO life delivers excellent mowing results. Where others struggle, SILENO gets the job done. If needed, you can easily wash your mower using your garden hose.

Simply lay the boundary wire around the area of lawn you want to mow, and lay the guide wire from the lawn back to the charging station . After the initial installation, the smart SILENO life bursts into life and will continue to mow independently within its mowing schedule. The CorridorCut function is specially designed to cut the lawn in narrow areas from 60 cm and dead ends.

Your reliable robotic mower tackles even the narrowest spaces and the tightest corners with reliable precision. Additionally, the frost sensor protects your lawn as it detects when the temperature is close to the freezing point and stops the mowing accordingly. Thanks to the SensorControl function, the SILENO life can measure grass growth and efficiently adjusts mowing times accordingly. Of course it's a GARDENA!

Bluetooth Connection

Simply pick up your smartphone and easily set up your SILENO life with the GARDENA Bluetooth App from up to 10 m. Benefits include EasyApp Control, Auto Schedule and EasyConfig for easy installation and use with zero fuss.


Relax in your garden while SILENO life quietly gets to work. The best in class low noise level (57db A) won't disturb you at all.


This lawnmower is an expert navigator, tackling the narrowest spaces and tightest corners with reliable precision.

Auto Weather & Terrain

SILENO life is a seasoned garden helper, getting to work in all weather, come rain or shine. This lawnmower cuts all shapes of lawns from simple to complex layouts, including slopes of up to 35 percent.

Ideal for medium-sized and complex lawn area layouts

The GARDENA SILENO life mows medium-sized lawn areas completely automatically, reliably, streak-free and evenly. It manages narrow corridors and tight passageways without a problem. The charging station can also be set up flexibly with nearly no restrictions.

Very cool

The clever frost sensor detects temperatures close to the freezing point and suspends the mowing plan to protect your lawn.

Safe and sound

The boundary wire determines the mowing area flexibly and yet reliably – ensuring that the Robotic Lawnmower only mows the areas specified. Highly sensitive collision sensors ensure that the Robotic Lawnmower is not stopped by garden obstacles. When the tool is lifted, another set of sensors make the blades stop immediately, thus preventing injuries.

Easy cleaning

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

Spot Cutting: You spin me right round!

The spot cutting feature, a spiral mowing function, makes the SILENO life ideal for hard-to-reach areas such as under trampolines or garden furniture — doing the hard work for you!
