How long does the robotic mower need to mow my whole garden?

The principle of the GARDENA robotic mower is to mow the lawn continuously. That means your garden is always freshly mowed. The needed time depends on the size and the complexity of your garden.
We recommend to let the robotic mower work five days per week. Of course he can also work the whole week. Here you can find an example how six working days per week can look like.

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

Generally is possible to place the charging station outside the working area. Please note that the area in front of the charging station is a high traffic location. The robotic mower should be able to start in any direction and return to the charging station from any direction. If the charging station is placed in a passage or outside the working area, it comes to a lot of turning processes, which causes a worn and flatted lawn. 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 (circa 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.
