Gardena Sileno city 250: The ideal robot lawn mower for small gardens

This robotic lawn mower has been specially designed for small gardens up to 250 m2. It is ideal as a second robot or for small, separate ancillary areas. It is equipped with a durable lithium-ion battery and manages gradients of up to ± 35 % or 14°. Its working volume is approximately 60 dB, making it much quieter than conventional lawn mowers.


The robot mower can even be used on complex lawns

Despite the low area performance, you can define up to three starting points for your robotic lawn mower. Therefore, it is also suitable for the use on complex lawns with multiple ancillary areas. Thus, the mower reliably finds its way even in hard to reach areas of the garden, which are accessible only through narrow passages.


Intelligent navigation through narrow passages

The robot lawn mower Gardena Sileno city 250 (15001-20) is equipped with the "EasyPassage" function. It enables the robot to navigate skillfully and efficiently through narrow corridors.


Gardena Sileno city 250 mows the lawn fully automatically

Timer function

The user-friendly LCD display allows you to set a mowing plan for your robotic lawn mower. So, it mows exactly when you want it to - even if it is raining. After a mowing cycle or when the battery is low, the mower automatically returns to the charging station to recharge.


Mulch function: Natural fertilizer for your lawn

While the robot mower navigates randomly through the garden, three blades mounted on a rotating disk shorten the lawn reliably. The cutting height can be adjusted between 20 and 50 mm. The fine cut grass falls to the ground as a mulch. There it is decomposed over time and serves the lawn as a natural fertilizer and moisturizer.


Various sensors for safe operation

For maximum safety, the Gardena Sileno city 250 is equipped with collision, lift and tilt sensors. When lifting or tilting the robot lawn mower, the knives stop immediately. When the robot encounters an obstacle, it stops and continues in another direction. A PIN code protects against theft and unauthorized usage.


Easy maintenance and installation

In just a few steps, the robot lawn mower is ready to mow. All accessories for the installation, such as boundary wire, cable pegs and connectors as well as detailed instructions are included in the scope of delivery.


Cleaning under running water

The Gardena Sileno city 250 weighs only 7 kg and is therefore extremely easy to handle. According to the manufacturer, this model may – in contrast to most other robot mowers – be cleaned under running water and with the garden hose.
