According to our robot lawn mower expert
The Gardena Sileno City Smart 250 robot lawn mower can mow lawns up to 250m². You'll find it even more convenient to control via the Gardena Smart System app (Android and iOS). This allows you to control the robot lawn mower from any location with a WiFi connection. This way, you can put the mower to work when you're not at home. Narrow passages between 2 lawns with a width of up to 60cm are no problem for the mower. Neither are tricky shapes in the lawn. In addition, the Sileno City Smart 250 adjusts the mowing frequency to the growth of the lawn with the SensorControl function.

The installation of the mower does take some time (although with the ongoing refund you can also choose to have it done), but once everything is installed, the mower works fine. What is striking is the low noise level with which the mower does its work; a soft buzzing sound and the occasional crackle when it actually mows is all that comes from under the hood. As mentioned, you have to take the time for the installation. A good place has to be found for the charging station and that is quite tricky since there must be a meter in front of the station and the boundary wires must also have a minimum distance. Then lay and secure the boundary wire. We have two trees in the grass, so 'islands' had to be placed around them, but that went without any problems. The manual offers a solution and the Gardena website also has clarifying videos. Finally, the guide wire has to be pulled and I believe it is mainly used to get the mower back to the charging station. That doesn't always go smoothly; regularly the mower spends ten minutes or more locating this wire. He then seems to go back and forth endlessly on the same little piece until he finally sees the light. We have microdrip sprinklers along the grass and it is important to place the boundary wire at a sufficient distance from this, otherwise you can place new sprinklers after each mowing. Occasionally the mower still shoots too far, resulting in a blown nozzle. Connecting to the gateway is easy and the integration with the other Gardena Smart products is fine and the app is very clear. To be able to use all functions, a firmware update had to be installed and unlike all other Smart devices that can be updated over-the-air, a screwdriver, laptop and old-fashioned USB cable had to be used. The upgrade software worked flawlessly. Because you have to keep a decent distance from walls and bushes, you can't escape the fact that you still have to cut the edges manually.

Installation is a bit of a mess, extra connectors are not a luxury. Nice device, mows pleasantly, grass is always healthy and happy. Animal protection, don't mow between certain hours, fine tune! Unfortunately, as advertised, this device does not work with Apple Homekit, and support was very rude about that.
All in all - recommended!
And the time you think you gain by not mowing yourself is lost by staring mesmerized at the mower. Delicious.
