Pros and cons

According to our robot lawn mower expert
  • You can control the robot lawn mower remotely from up to 10m via Bluetooth in the Gardena app.
  • Thanks to the maximum incline of 35%, you can also mow hilly fields and pond edges.
  • The robot lawn mower doesn't drive into unexpected obstacles like toys thanks to the collision sensors.
  • Due to the small cutting swath and shorter battery life, the robot lawn mower can only mow lawns up to 250m2.

The included perimeter wire leads the robot lawn mower automatically and reliably to all mowing areas. Also slopes up to 35% are no problem for the Sileno City 250 robot lawn mower.

Does a good job with nice results

  • Quiet
  • Easy installation
  • Easy programming
  • Factory software upon purchase

Moderate mowing results in the beginning (a lot of turning and turning, irregularly mowed lawn with tufts of longer grass, despite many more hours per day than recommended setting), but evidently good improvement with software update from July 2020. After this, mower comes everywhere and is efficient and can be done according to advice keep your lawn looking beautiful for hours a day. Only leave clumps of grass in wet weather. Gardena's predecessor did not do this. Does its job quietly.

Extremely quiet, but setting schedule takes some effort

  • Very quiet
  • Device design
  • Manual is not clear enough

We had some trouble setting up the robotic lawnmower. The wiring went well, but setting the schedule of how it automatically departs is complicated and is also poorly explained in the manual. Take enough time for this. We can't say anything about the mowing performance yet.

Top product, the app also works fine

  • The robot itself is virtually plug & play
  • Operation is very simple
  • Our lawn looks perfect after just one week
  • If you can speak of a downside! Installing the Perimeter Wire is a chore. We dug it in, but then you will never be bothered by it again.

After you have installed everything, you will be mowing the lawn in no time.
