Pros and cons

According to our robot lawn mower expert

You can mow lawns up to 800m2 thanks to the wide cutting swath and powerful battery.
With the GARDENA smart system, you can control the robot lawn mower from anywhere and easily check the mowing route, even when you're not at home.
The collision sensors prevent the robot lawn mower from driving over unexpected obstacles, like toys.
Without cliff sensors, the robot lawn mower can drive off of cliffs like stairs and ditches.

Description

Mow your lawn up to 800m2 with the GARDENA smart SILENO Free 800. You don't need a perimeter wire. The robot lawn mower has cameras and sensors that determine the border themselves. Choose the cutting height between 25 and 45mm yourself. Thanks to this, you have the right height for every lawn. With the mulching function, the robot lawn mower blows the cut grass back into your garden as a nutrient. You can use the robot lawn mower with an app via Bluetooth or with the GARDENA smart system. You can adjust mowing schedules and control the mower remotely this way. Calmly read a book while the lawn mower is working. With a 58dB noise level, it doesn't make much noise.

Fast, impressive and effortless

setting up takes time

After extensive use of my robot, I finally feel empowered to write a good and informative review for those who are hesitant.

You do have to put in some effort to set up the robot. It's definitely not plug and play. Once you've done that, you're done and don't need to touch it again. The app is "where all the magic happens." Here you can configure everything to your liking and track the robot. The robot connects via Wi-Fi and GPS. Therefore, it's VERY important that the view isn't obstructed. If you have large trees, the robot might lose its signal, making it unusable. Therefore, it's not suitable for every lawn. Once it's up and running, it's fantastic. I can define zones where the robot shouldn't go for any reason. The robot avoids objects on the ground and walls. It's safe to use. I'm particularly impressed with the speed and the mowing radius. A garden is done in just a few hours, and the best part is, you don't have to be there.

Robot lawn mower takes everything with it and is silent

app
battery
no protection against rain when stationed

Not my first robot mower, but it's the most impressive and best one yet. The app is what really stands out to me. It's easy to use and offers a variety of options to keep my garden tidy. The noise is also significantly quieter. The battery is much, much better. It lasts a whole day without any problems. My wife and I love it. We lie down in the garden and while we read a book, the robot mower does what it's supposed to. I still need to delve into the app, though, as there are features I haven't tried yet. The grass is even and gets a nice cut. It's even usable in strong winds, like we've had the past few days. I placed the station under a parasol to keep it from getting unnecessarily wet. It's waterproof, as far as I understand, but I can't imagine that being left in the rain 24/7 will improve its durability.

My wife and I are happy with the robot mower.
