According to our robot lawn mower expert
The robot lawn mower uses AI to get to know your lawn and growth patterns and adjusts the mowing schedule accordingly.
With the GARDENA smart system app, you can control the robot lawn mower from anywhere and easily check the mowing route even when you're not home.
Thanks to the maximum incline of 30%, you can also mow hilly fields and ditch edges.
Due to the small cutting swath and shorter battery life, the robot lawn mower can only mow lawns up to 400m2.

The Gardena Smart Sileno Sense 600 mows my lawn perfectly while I go grocery shopping.
Installation and app
After taking the robotic mower out of the box, I read the installation manual. Because this is my first robotic mower, I didn't immediately know how to install the robot. But after watching a video from Gardena, I figured it out. Once up and running, the robot explored my lawn. That is how it learned its mowing route. In the app, I specified the mowing length and the areas where the robot should drive slowly.
Precisely mowed The lawn slopes slightly at my driveway. Even there, it drives smoothly over the grass without the wheels slipping. When the robot turns, it does so gently, and I never see gaps in my lawn. Even where I have a bit more moss in the grass, it mows without any problems. Because the robot has a low noise level, the mower hardly disturbs me when I am sitting in the garden. This allows me to do my sudoku in peace while the robot mows. Base Station
When the robot has finished mowing, it returns to its base station on its own. There, it recharges for the next mowing session. I built a shelter for the robot next to my shed, but I can also buy a separate garage to place on top of the base station. This protects the robot from rain, wind, and leaves. Without a garage, the robot breaks down faster.

I am very disappointed for the price; it bumps into everything and is already completely damaged after 1 hour of use.
