In-depth Review

Gardena smart Sileno City 500 Review

Quiet & Compact – The Urban Garden Specialist

The Gardena smart Sileno City 500 is the quietest robot mower in our test. At only 56 dB operating noise, it is barely audible – quieter than a normal conversation and significantly quieter than most vacuum cleaners. This makes it the ideal choice for densely populated residential areas, terraced house gardens, and for operation in early morning or evening hours.

With its compact dimensions (57 × 43 × 24 cm), the Sileno City fits through narrow passages and garden gates from 43 cm width. This is a decisive advantage for irregular urban gardens with tight spaces. The low weight of only 7.5 kg also makes transport and handling easy.

Smart Gardening with the Gardena App

The Gardena smart App combined with the optional Gardena smart Gateway opens up a wide range of control options. Besides scheduling, multiple Gardena devices (irrigation control, soil sensors) can be networked together. The mower can be controlled remotely, and the app sends notifications when mowing is complete or if errors occur. The user interface is intuitive and designed for both beginners and experienced users.

Installation is particularly easy thanks to the plug-and-play system: the boundary wire is laid along the lawn edge, clicked into the charging station, and the mower starts its first mowing cycle after brief configuration. The smart functions require the Gardena smart Gateway, which is sold separately.

Conclusion

The Gardena smart Sileno City 500 is the perfect choice for urban gardeners with small areas up to 500 m². It combines extremely quiet operation with well-designed app integration and easy installation. For larger areas or more demanding terrain, it lacks the necessary power.

FAQ

Frequently Asked Questions

How loud is the Sileno City 500 really?

At 56 dB, the Gardena Sileno City 500 is the quietest robot mower in our entire test field. For comparison: a normal conversation is about 60 dB, a refrigerator around 40 dB. The mower is barely audible from a few meters away – not noticeable indoors at all. Neighbor complaints are practically impossible.

Do I need the Gardena smart Gateway?

For full smart functionality (app control, schedules, notifications), the Gardena smart Gateway is required and sold separately. Without the Gateway, the Sileno City 500 can only be controlled via the control panel on the mower itself – basic mowing functions work without the Gateway. The Gateway is worth it if you operate multiple Gardena smart devices or want to control the mower remotely.

What garden size is the Sileno City suitable for?

The Gardena Sileno City 500 is designed for areas up to 500 m² – ideal for typical urban gardens, terraced house gardens, and front gardens. The battery life of approximately 70 minutes is sufficient for these areas; the mower automatically returns to the charging station when needed and resumes work after charging.

Does the Sileno City have theft protection?

No, the Gardena Sileno City 500 does not have integrated theft protection. There is no GPS tracking or PIN code. In areas with higher theft risk, we recommend securing the mower after use or choosing a model with theft protection.

Is the Sileno City suitable for slopes?

The Gardena Sileno City 500 handles slopes up to 25%. This is sufficient for most urban gardens with gentle inclines. For steeper gardens, we recommend models with higher slope capacity such as the Husqvarna 450X NERA (70%) or Worx Landroid L2000 (35%).
