Problem
Encountered
Probable Cause/Event Corrective Actions
Poor quality of
mowing
- Dull blade - Replace blade.
- The grass is too high in relation to the set
cutting height.
- It is recommended to cut less than a 1/3 of the
green part of the grass.
- Set the cutting height to a higher position and
then successively lower.
- If it is during a fast growing season – change the
Interval (refer to Section 6.4.2 – P001).
- The grass is wet and causes
accumulation of grass clippings around
the blade.
- For best cut, operate Robomow when the grass
is dry. Do no to mow in the early morning hours.
- Switch Off the Safety Switch and use heavy
gloves to clean and remove the grass clippings.
Mower doesn’t
find the Base
Station
- There is a Perimeter Island or a Narrow
Passage that prevents the mower to
complete its drive towards the Base
Station in Near Wire Follow mode.
- Reduce the Near Wire Follow Distance in the
Settings menu from the default 7.
Robomow
is noisy and
vibrates
- Damaged or unbalanced blade
- Check if the lawn is free from branches, stones
or other objects that can damage the blade.
- Replace the blade
Mower does not
dock properly
and sometimes
misses the Base
Station contacts
- Height differences between the lawn and
the Base Station surface.
- Fill some ground to flatten the lawn to the Base
Station to allow smooth entrance.
- The wire underneath the Base Station is
not tight and placed in the middle of the
Station.
- Confirm the wire underneath the Base Station
is straight, tight, and centered below the Base
Station.
- The Base Station is set up on a side
slope.
- Move the Base Station to a relatively level
ground.
- The Base Station is placed too close to
the corner of the lawn
- Move the Base Station so it is not within 3 meters
from a corner.
Uneven mowing
results
- The time between operations is too long
because of long inactive time windows.
- Minimize the Inactive Time windows to allow
Robomow to complete the Mowing Cycle faster
and to achieve even mowing results.
- Grass is growing very fast.
- If it is during a fast growing season – change the
Interval (refer to Section 6.4.2 – P001).
- The shape of the lawn is complicated
(Narrow Passages, obstacle and islands).
- In a complicated lawn more time is required for
the lawn to achieve better mowing results.
- Increase the Intensity (refer to Section 4.3.2.1).
- The set area is smaller than the actual
lawn size.
- Increase the zone area (refer to Section 4.3.3
Edit an existing Zone).
Robomow
operates during
Inactive Time.
- Wrong clock time is set in the mower.
- Verify that the time on the mower is set correctly.
- Set the time (refer to Section 4.4.4).
- Reset the Inactive Time (refer to Section 4.3.1).
Cut wire indicator
is flashing on
Power Box
- The Extension Cable is disconnected or
damaged between Power Box and the
Base Station.
- Confirm the Extension Cable is plugged in and
wire leads are firmly attached.
- Perimeter Wire is cut.
- Walk along Perimeter Wire.
- Look for cuts or breaks in the wire.
- Repair with Robomow wire splice connectors.
The poor
connection
indicator is
flashing on
Power Box
- Poor connections
- Check and repair all loose, poor, or corroded
connections.
- Twisted cables, or a screw terminal which
is insulated with insulation tape is not a
satisfactory splice.
- Soil moisture causes the conductors to
oxidize.
- Use the connectors supplied in the box. They
are waterproof and give a reliable electrical
connection.
