Gardena Sileno City 500 m² robotic lawn mower (15002-20)

What does the Gardena Sileno City 500 m² do for your lawn?

The Gardena Sileno City 500 m² robotic lawn mower takes over regular mowing in small and medium city gardens of up to around 500 square metres. It works quietly, returns to the charging station on its own and keeps your lawn evenly trimmed without you having to push a mower.

While mowing, the robot mulches the grass into fine clippings. These remain on the lawn as natural fertiliser. This saves you the hassle of collecting and disposing of grass cuttings and helps the soil retain moisture.

Who is the Sileno City 500 m² suitable for?

This model suits you if you have a manageable lawn and want to spend little time on lawn care. Compact city and terraced house gardens benefit from its small footprint and low noise level.

• Lawn areas up to approx. 500 m²
• Homeowners who want automatic lawn care
• Users who value quiet operation in residential areas
• Gardens with corners, narrow passages and smaller zones

What are the everyday benefits of the Gardena Sileno City 500 m²?

Less work, more free time

Once installed, the Sileno City follows the schedule you set and starts mowing automatically. You no longer need to plan fixed mowing times and gain several hours of free time each week.

The frequent, even cut promotes a dense lawn surface. Thanks to its driving pattern, the robotic mower can also reach edges and awkward areas that are difficult to access with a standard mower.

Quiet operation in built-up areas

The Sileno City is designed for use in densely built-up residential areas. Its mowing noise level is significantly lower than that of a petrol lawn mower. It can therefore work in the early morning or evening without disturbing your neighbours.

Simple control and flexible settings

You control the mower via a clear, easy-to-understand menu on the device. You define on which days and at what times the robotic mower should run. You can adjust the cutting height in steps so the look of your lawn matches your garden style.

• Programming of mowing times directly on the device
• Adjustable cutting height to suit your preference
• Automatic return to the charging station when the battery is low

Key functions and technical characteristics

Safe navigation in your garden

The Gardena Sileno City moves within a boundary wire laid around the lawn. This cable defines which areas are mown and which zones, such as flower beds or gravel areas, are excluded. The robot recognises obstacles and navigates around trees, beds and garden furniture.

Sensors help it detect collisions, slow down and change direction. If you lift the mower, the blades stop for safety. This reduces the risk of injury during handling.

Designed for typical city gardens up to 500 m²

With its capacity for up to 500 m², the Sileno City covers many common lawns in residential and terraced house plots. It can usually cope with light slopes and smaller inclines. If narrow passages are included in the boundary wire, the mower can drive through them as part of its mowing routine.

What should you check before buying?

Measure your lawn area before you choose the Gardena Sileno City 500 m². The total mowing area should remain within the specified 500 m² to ensure reliable operation.

• Roughly measure the total lawn surface in square metres
• Consider the shape of the garden, including corners and narrow paths
• Plan a power socket for the charging station at the lawn edge
• Lay the boundary wire around beds, ponds and gravel or bark areas

If you take these points into account, the Gardena Sileno City 500 m² (15002-20) becomes a dependable helper that keeps your lawn neatly trimmed throughout the mowing season with minimal effort from you.
