Pros and cons

According to our robot lawn mower expert
  • You can control the robot lawn mower with the Gardena Smart System app (Android and iOS) via WiFi on your smartphone or tablet.
  • The SensorControl monitors the growth of the lawn and adjusts the cutting frequency accordingly.
  • The frost sensor prevents the robot lawn mower from mowing at temperatures below 5 degrees Celsius.
  • Depending on the layout of your garden, 150 meters of perimeter wire may not be enough.

Description

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.

    Very quiet mower

    Marc de Best | 11 July 2020 | Lawn surface: 250m² | Control with app via WiFi | Automatically translated from Dutch

    • Extremely quiet
    • Clear installation guide
    • mow well
    • Has no trouble with bumps / potholes
    • You still have to cut the edges yourself
    • Has some trouble finding his 'home'
    • Shoots over the boundary wire sometimes

    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.

    I should have bought much sooner!

    Nico Brouwers | 7 August 2020 | Lawn surface: 250m² | Control with app via WiFi | Automatically translated from Dutch

    • Quick installation
    • Neat mowing result
    • flexible adjustment of wire and wire crossing
    • Powerful engine, good grip on all terrain
    • haven't run into the pool yet
    • I should have bought years ago
    • Powerful motor, sometimes wants to keep driving against an object so that it scrapes the grass from the ground. with its wheels

    Exceeds expectations with flying colors.

    Nice device, some tinkering, no Apple Homekit

    Bram Van Oost | 9 August 2021 | Lawn surface: 250m² | Control with app via WiFi | Automatically translated from Dutch

    • Mows very nicely
    • OK app, some usability issues, but works.
    • Very entertaining
    • Your grass is happier and healthier
    • Animal mode, won't mow between certain hours
    • Does NOT work with Apple Homekit despite advertised
    • Support is slow (weeks)
    • Forgetting code is misery :-)
    • Tricky job to install, once done and adjusted it works fine

    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.

    Expensive but decent.
    • Beautiful, robust container
    • Easy to use
    • The dance with the cables is annoying
    • Expensive
    • Apple Home not started yet
    • Random patterns, no intelligence
    • Doesn't take the edges

    Nice box, feels robust, works pleasantly. The "disadvantages" are (perhaps) specific to the type of devices, the fiddling with perimeter cables and the random mowing patterns are not exactly user friendly.

    recommended
    • almost silently
    • don't worry
    • easy programming via the app
    • the sides that still have to be done yourself are quite wide

    recommended, the grass remains short without any effort

    I will definitely not buy the same one ever again
    • Mows well just not the sides
    • Makes a lot of noise, just like an old-fashioned hand mower
    • The appliance does not mow around the edges
    • You still have to mow 20 cm edges yourself
    • Not controllable by remote control

    When I look at what we've paid, and how much grass we still have to cut short in some other way, I don't think it's worth the money. Not at all in combination with the sound. If you think you've purchased an advanced device, don't expect the sound of a rusty hand mower!

    Definitely worth the money!
    • Easy to install
    • User friendly
    • Definitely worth the money
    • No negatives

    It took a while to figure out how to put the station in a corner. But the rest is pretty easy to install. Very content and easy to use. The App also tells you step by step what to do.

    Best price/quality for a small garden!
    • Ideal for small garden
    • Everything is included, no additional installation kit or purchase required
    • Easy to use with the Gardena app
    • Supplied ground spikes break easily

    Price is all-in for a small garden and therefore good quality for its price!
