Robotic lawn mower Gardena SILENO minimo

The GARDENA Robotic Lawnmower SILENO minimo 250 m² is a compact autonomous mower designed for small lawns up to 250 m². It features a 160 mm cutting width, battery operation and a compact housing (340 × 520 × 220 mm) that is easy to store. Controlled via the GARDENA Bluetooth® App from up to 10 m, the SILENO minimo offers automated scheduling, corridor navigation for narrow passages and a frost sensor that pauses mowing near freezing temperatures.

Advantages

The SILENO minimo connects to a smartphone through Bluetooth® for straightforward setup and scheduling. Its low noise level (57 dB(A)) allows quiet operation while SensorControl adjusts mowing frequency to grass growth for efficient trimming. CorridorCut enables reliable navigation in narrow spaces and tight corners, and the mower handles slopes up to 25% and returns automatically to the charging station when finished. The design supports easy cleaning with a garden hose and safety features such as collision sensors and blade-stop sensors when lifted.

Suitable for

• Small lawns up to 250 m²

How to use

Install the boundary wire and guide wire to define the mowing area and guide routes. Use the GARDENA Bluetooth® App on your smartphone to enter the lawn size, select desired mowing days and preferred start times; the app walks you through initial configuration step by step. Place the charging station in a suitable location, put the mower on charge until ready, and allow the SILENO minimo to operate autonomously. The mower will follow its schedule, navigate narrow corridors, pause when frost is detected if that feature is enabled, and return to the charging station when the task is complete.

Usage recommendations

For reliable performance, keep the boundary wire intact and free of heavy debris, clean the housing, blades and wheels with a garden hose regularly, and check the app settings for frost sensor and scheduling preferences. Ensure the lawn is free of large objects and short obstacles to reduce collisions and allow optimal navigation.
