Gardena Sileno City 250 m² Smart Robotic Lawnmowers - Grey & Turquoise | 19069-28


The smart robotic lawnmower for lawns up to 250 m²

Learn how easy it is to take care of your lawn with your smart Robotic Lawnmower smart SILENO city! With its SensorCut system, the GARDENA smart SILENO city mows your lawn accurately and reliably. Input the desired height of the grass and in combination with the SensorControl feature the robot decides for itself if it is a good moment for mowing and adjusts accordingly. And with the intelligent spot cutting function, a spiral mowing function, you place your SILENO in hard-to-reach-areas and it will mow there as well. The efficient assistant is particularly quiet, so you can continue to relax in the garden while he does your work. The smart SILENO city will automatically return to the charging station when the mowing is completed.
The Robotic Lawnmower registers thanks to its Frost sensor if the ground is frozen. If it is frosty, the robot halts its program until the ground is dewed. It masters inclines of up to 35 percent as well. With the help of the sophisticated CorridorCut feature the robot cuts the grass in narrow corridors and even in dead ends of just 60 centimetres width without problems – areas that you usually would have to come by manually. During installation, a programming assistant guides you through the menu and independently calculates the mowing plan. The mowing times can also be set via GARDENA 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. The app includes handy benefits like Instant Control, Scheduled Control, an easy and guided configuration as well as a Plant Library. With Instant Control you can take care of your garden wherever you are, with a tap of our easy-to-use GARDENA smart App.
With Scheduled Control, there is no need for reminders - the GARDENA smart App will do the job for you! The GARDENA smart App also provides easy and guided configuration with step-by-step guidance for setting up your own smart system. It comes with clear illustrations, tips and helpful wizards to create mowing schedules. You can watch our installation videos for helpful tips, and should you have any further questions, our customer service will be more than happy to help you. Never leave your garden behind.

Ideal for small and complex lawn areas

The GARDENA smart SILENO city mows small and complex 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. You get an insight about it in the GARDENA smart app, too.

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 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.
