2.2 Function
 
Capacity 
 
The robotic lawnmower is recommended for lawns up 
to 700 m

 in size (400 m

 for the R40Li).
How big an area the robotic lawnmower can keep cut 
depends primarily on the condition of the blades and 
the type, growth and moisture of the grass. The shape 
of the garden is also significant. If the garden mainly 
consists of open lawns, the robotic lawnmower can 
mow more in one hour than if the garden consists of 
several small lawns separated by many trees, flower 
beds and passages.
A fully charged robotic lawnmower mows for 40 to 
60 minutes, depending on the age of the battery and 
how thick the grass is. Then the robotic lawnmower will 
charge for 60 to 90 minutes. The charging time can 
vary depending on, among other factors, the ambient 
temperature.
 
Mowing technique
 
The robotic lawnmower's mowing system is based on 
an efficient and energy saving principle. Unlike many 
standard lawnmowers, the robotic lawnmower cuts 
the grass instead of knocking it off.
It is recommended to allow the robotic lawnmower to 
mainly mow in dry weather to obtain the best possible 
result. The robotic lawnmower can also mow in the 
rain, however, wet grass easily sticks on the robotic 
lawnmower and there is a greater risk of slipping on 
steep slopes.
If there is risk for thunder, the transformer should be 
disconnected from the power and the boundary wire 
and the guide wire from the charging station. 
The blades must be in good condition to obtain the 
best mowing result. In order to keep the blades sharp 
for as long as possible it is important to keep the lawn 
free from branches, small stones and other objects. 
Replace the blades regularly for the best mowing 
result. It is very easy to replace the blades. See
