Auto Weather & Terrain

SILENO 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 small and complex lawn areas

The GARDENA SILENO city mows small and complex lawn areas completely automatically, reliably, evenly and streak-free. 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 reliably – ensuring that the Robotic Lawnmower only mows on specified areas. 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 city has been constructed so that a thorough spraying with a garden hose 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 city ideal for hard-to-reach areas such as under trampolines or garden furniture — doing the hard work for you!
