If the working area consists of two separate lawn areas where the Robotic Lawnmower can’t move by itself, we recommended making it possible to lay the wire to the other areas. In this case, the Robotic Lawnmower is supported manually between main and secondary areas. Use the MAN mode / other area and the Robotic Lawnmower mows until the battery is empty. Using this method, you will need to take the Robotic Lawnmower to the charging station by yourself.

See the operating instructions for detailed information about this procedure.

The area in front of the charging station is a high-traffic location. The Robotic Lawnmower should be able to start in any directionsand return to the charging station from any direction. For the (smart) SILENO city / SILENO / SILENO+ you have a choice of where to position the charging station. For further information, see section "How to install the charging station for the GARDENA Robotic Lawnmower" in the operating instructions.

It is better to avoid long narrow passages and Areas narrower than 1.5 m. Otherwise the Robotic Lawnmower might mow the passage for too long or be unable to remove itself from the passage.

That depends on the Robotic Lawnmower. R38Li, R40Li, R45Li and R50Li: The minimum width is 90 cm between the boundary wires. R70Li, (smart) SILENO city / SILENO / SILENO+: The minimum width is 60 cm between the boundary wires.

The width of the uncut grass strip depends on how close the boundary wire can be laid to the edge of the lawn.

• e.g. at 5 cm (R38Li, R40 Li, R45Li, R50Li and R70Li) or 10 cm ((smart) SILENO / SILENO+) from the lawn edge, along brick paths that can be passed by the Robotic Lawnmower, there will be no uncut grass strip.
• e.g. at 20 cm (R38Li, R40 Li, R45Li, R50Li and R70Li) or 25 cm ((smart) SILENO / SILENO+) from the lawn edge, along beds or crushed rock that cannot be driven by the Robotic Lawnmower, there will be a narrow strip of grass.
• e.g. at 30 cm (R38Li, R40 Li, R45Li, R50Li and R70Li) or 35 cm ((smart) SILENO / SILENO+) from the lawn edge, along a wall or around trees, there will be a slightly wider strip of grass.

To make sure that the grass is completely mowed or that only small strips of uncut grass are left, change the layout of your garden, for example by edging the lawn with curb stones or concrete slabs at lawn height.
