The robot lawn mower for the small garden: Gardena Sileno City
This robotic lawn mower is specially designed for small lawns up to 250 m2. It is an ideal additional robot for small, separate ancillary areas. It is equipped with a robust Lithium ion battery and manages gradients of up to ±25 % (14°). The volume while working is only about 60 dB which equals the volume of a normal conversation.


Small robot mower, great performance – even on complex terrain
Despite the low area coverage, you can set up to three starting points for your robotic lawn mower. Thus, it is also suitable for the usage on a complex property with several ancillary areas because it finds its way in remote areas of the garden which are connected to the main area only through narrow corridors. This ensures an optimum mowing result all-over.


Intelligent navigation through narrow passages
The Gardena Sileno City robot lawn mower is equipped with the feature “Easy Passage” and therefore is able to navigate efficiently and quickly through narrow corridors.


Gardena Sileno City mows your lawn fully automatically
Mowing schedule
With the user-friendly LCD display with keypad you can set up a weekly schedule for your robotic lawn mower. It follows the schedule even when it is raining. After work or when battery is low, the automatic lawn mower returns to the charging station to recharge.


Mulching function for a healthy lawn
Three blades which are mounted on a rotating disc cut the lawn reliably while the robot mower crosses the garden at random. The cutting height can be individually adjusted between 20 and 50 mm. The fine grass cuttings fall down to the ground where they are slowly decomposed and serve the lawn as a natural fertilizer and moisturizer.


Sensors assure a safe operation
The Gardena Sileno City 250 is equipped with collision, lift and tilt sensors for maximum safety. If the robot hits an obstacle it stops and navigates into another direction. If lifted or tilted, the robot lawn mower’s blades stop immediately. A PIN code protects it against theft or unauthorized usage.


Easy maintenance and installation
After just a few steps, the robot lawn mower is ready for operation. All accessories needed for the installation, like perimeter wire, pegs, cable connectors and the user’s manual, are included in the scope of delivery.
