The SILENO City 250 - The smarter way to mow

With a fully automated GARDENA Robotic Lawnmower, you can enjoy a perfectly mowed, lush green lawn while you enjoy yourself doing other things with your free time. But why is a GARDENA Robotic Lawnmower the best choice? Discover five unbeatable reasons.

SILENO City - Quiet

The quietest robotic lawnmower around

While comparable robotic lawnmowers can operate at up to 68 dB(A), the SILENO city operates at just 58 dB(A) - that's just half the noise level. The perfect way to maintain your lawn while maintaining peace in your garden!

Agile and efficient thanks to the patented guide cable

Your robotic lawnmower knows where to go.

Thanks to its advanced technology, it will reach every remote area of your lawn - even through passages as narrow as 60cm in width. Thanks to the guide wire, your SILENO City will always find the fastest route back to the charging station.

SILENO City - Narrow Passageways
SILENO City - All Weather

Works in all weathers

GARDENA Robotic Lawnmowers have no rain sensor. Why? It's simple: They don't need one. While other automatic lawnmowers start travelling back to the charging station when it starts raining, the SILENO City simply carries on mowing. Thanks to its sophisticated design, rainy days, wet grass and dirt are not a problem. 

Stay cosy and dry while your robot does the work for you - completely autonomously.

Top notch after-sales service
