Teun & Katrien: Border edges and height next to the grass
Yes, the robotic lawnmower makes a round in the middle over the boundary wire. Whether the mower then takes all the grass edges depends on a number of factors.
Terrace/path/garden
If the terrace/path is level with the height of the grass, the boundary wire can be laid at the edge.
The mower always drives in the middle over the wire. In these places, the mower can therefore take everything with it.
See the drawing below.

Walls and Fences (vertical objects)
The boundary wire must have a distance of 30-35cm in places where there is a wall or vertical obstacle.
This also applies if the terrace is higher or lower than the grass. In these places, the robot will therefore not mow all the way to the vertical object/wall. The best solution here is to place a row of stones along the wall, so that the robot neatly takes everything with it.
