Roots
Do not, under any circumstance, leave areas which have not
been delimited by barriers inside the work area, as these will
prevent the robot from functioning properly (roots, external
pipes, work tools, etc.).
EN
Fine gravel
Danger - Attention
If fine gravel, leaves or small stones are used to
border the lawn, they are not detected correctly
by the robot. Protect the lawn with other borders.
Sharp corners
Danger - Attention
In areas of the lawn that end in narrow spaces as
shown in the figure, the robot cannot move easily,
therefore this part of the lawn must be excluded
because the robot would exit the borders.
