Can I use a GARDENA Robotic Lawnmower in two separate areas?

If the work area consists of two areas between which the robotic lawnmower can not move freely, it is advisable to create a secondary area by laying an independent boundary wire. In this application, the Robotic Lawnmower is carried by hand between the main area and the secondary area. Use the operating mode MAN / secondary area, the robotic lawnmower then mows the secondary area until the battery is empty. The robotic lawnmower is then carried back to the charging station in the main area for charging.

Further information can be found in the operating instructions.

Must the charging station be placed on the lawn or could it be placed in a garden bed?

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