Robotic lawn mower Gardena SILENO city

The GARDENA Robotic lawn mower SILENO city is designed for lawns up to 600 m². Compact and efficient, it features a 160 mm cutting width, a lithium‑ion battery with a short charging time (approx. 1.15 h), and a small footprint (380 × 550 × 230 mm). The mower works autonomously using boundary and guide wires, handles slopes up to 35% and can be cleaned easily with a garden hose.

Advantages

The SILENO city offers Bluetooth® control via the GARDENA Bluetooth® App from up to 10 m, automatic scheduling with SensorControl that adapts mowing frequency to grass growth, and Auto Weather & Terrain functionality that lets it operate in most weather conditions while pausing when the ground is frosty. With a low noise level of 57 dB(A), CorridorCut navigation for narrow passages from 60 cm wide, sensitive collision and lift sensors for safety, and a spot cutting spiral mode for hard‑to‑reach areas, the mower delivers precise, low‑maintenance lawn care.

How to use

Install the boundary and guide wires according to the user manual to define the mowing area and passages. Use the GARDENA Bluetooth® App to configure the lawn size, desired mowing days and preferred start times; the app assists with initial setup and auto scheduling. Place the charging station in a suitable, accessible location and allow the SILENO city to charge fully before first use. The mower will operate autonomously, returning to the charging station as needed. Clean the housing, blades and wheels with a garden hose after use as required.

Usage recommendations

Use a valid email and set up a GARDENA user account to access app functions. Position the boundary wire to include only the areas you want mowed, check passage widths of at least 60 cm for CorridorCut navigation, and avoid operating on heavily frozen ground — the mower will suspend work if frost is detected.
