2. PRESENTATION
2.2 Function
Capacity
The robotic lawnmower is recommended for lawns up
to 700 m
2
in size (400 m
2
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
8.6 Replacing the blades
