Can I use a GARDENA Robotic Lawnmower for separate lawn areas?

If the area consists of two separate lawn areas where the Robotic Lawnmower can’t go by itself, we recommend 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 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.

Does the charging station need to be placed on the lawn or could it be placed on a vegetable patch?

The area in front of the charging station is a high-traffic location. The Robotic Lawnmower should be able to start in any direction and return to the charging station from any direction. For the (smart) 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.

How small can the narrow passages for the GARDENA Robotic Lawnmower in my garden be?

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.

How narrow could passages (approx. 1 m length) for my GARDENA robotic mower be?

The minimum width consists of several factors. First of all, the minimum distance between the boundary cables must be 60 cm. Additionally to this the distance to an obstacle must be considered and also added to the minimum distance of 60 cm from one boundary cable to the other.

Example: Minimum width between two house walls for a SILENO city
Distance between house wall and boundary cable on both sites: 35 cm
Minimum distance: 35 cm + 60 cm + 35 cm = 130 cm
In the operation manual you can find exact model specific information regarding distances, dependent on the type of obstacle.
