Robomow City 120
How It Works
• A one-time setup is required before operating Robomow; a small wire, called the perimeter wire, is placed around
the edge of the lawn and any other areas where you do not want the mower to enter.
• Small pegs are supplied with Robomow and they are used to fasten and hold the perimeter wire to the ground,
below grass level; the wire will soon disappear under the growth of new grass and will not visible.
• The Base Station is placed along the perimeter wire and it has two main functions:
- To generate a small signal along the perimeter wire (very low voltage);
- To charge Robomow batteries.
• After completing the one-time set-up of wire around the lawn including the Base Station set the weekly program
and forgets about mowing for the entire season!
• Robomow will leave the Base Station on the day and time scheduled in the automatic weekly program; it will mow
the lawn and will drive back for charging in the Base Station to be ready for the next operation.
• When Robomow leaves the Base Station it automatically starts the signal carried through the Base Station; the
signal creates a virtual wall, which is visible only to the Robomow, keeping it inside the lawn preventing it to cross
over area where you do not want it to enter.

Planning
Chapter 1 Planning
Before starting the setup, please read this chapter fully and watch the setup
DVD. This will help you determine the best location for the Base Station, for
the perimeter wire layout, or for the Perimeter Switch.
1.1 Determine Base Station location
Robomow’s Base Station is placed along the Perimeter Wire. This is where
the wire “loop” starts and ends. The Base Station has two main functions:
● It generates a small signal along the perimeter wire (very low voltage),
which serves as an “invisible wall” setting the lawn boundaries for
Robomow.
● It charges Robomow’s batteries.
After completing the one-time set-up of the Perimeter Wire and the Base Station,
a weekly program is set. That’s when Robomow does your mowing for the entire
season!
Robomow leaves the Base Station on the day and time scheduled in the automatic
weekly program. It mows the lawn and it returns to the Base Station for recharging.
First, you decide where the Base Station will be placed…
QInside the lawn area, along its outer edge.
Or:
QOutside the lawn area
1.1.1 Consider the following in order to
choose the best location:
PIf the lawn has more than one zone, set the Base
Station within the largest plot or zone.
PMake the Base Station invisible to the street.
PPrefer a shady spot.
This will extend battery lifetime
PPlace the Base Station on a relatively level ground.
PDo NOT place it on a slope.
PPlace the Base Station at least 1 meter from corners.
PPlace the Base Station away from sprinkler heads.
Water or rain does not harm Robomow. However, we
recommend a distance from sprinklers for maximum protection.
1.1.2 If Base Station is to be located outside the lawn area
External setup of the Base Station allows the Base Station to be located
outside the lawn area, close to its edge.
Consider the following in order to choose the best external
location:
PChoose a place close to the lawn edge.
PThe passing between the lawn and the Base Station
should be smooth, with no height differences.
This will enable Robomow to follow the wire smoothly to its Base
Station.
PThe surface of the external area should be hard (e.g. a
sidewalk, firm ground). It should not be sandy or stony.
This will prevent Robomow from slipping or getting stuck.
Option A - Internal setup

Option B - External setup

Chapter 1-2
Robomow City 120
1.1.3 Determine location of Power Supply
PThe Base Station should be close enough (15 m/50 ft) to
a wall electrical socket (230V / 120V). The indoor Power
Supply unit will be connected to it.
PRobomow’s 15 m (50 ft) low voltage cable connects
to the power supply unit. The length of the low voltage
cable must NOT be changed.
PSelect the right location for the power supply unit:
The power supply is suitable for outdoor use, yet it is required
placing it in a sheltered place, dry location, which is well ventilated
and not exposed to direct sunlight.
1.2 Planning the Perimeter Wire’s layout
The Perimeter Wire functions as an “invisible wall” for Robomow. It sets
the boundaries of lawn zones and it surrounds specific areas where you
do not want Robomow to enter.
The Perimeter wire is held to the ground with small pegs, supplied with
Robomow. Soon after setting, the wire will become invisible under the
growth of new grass.
As soon as Robomow starts operating, it turns on a signal that runs along
the Perimeter Wire. This signal keeps Robomow within its working zones
and away from preset demarcated areas.
1.2.1 Is your lawn a single contiguous area?
If grass areas are contiguous, Robomow
will automatically mow all zones tracking the
Perimeter Wire you set around the lawn.
1.2.2 Does your lawn have more than one zone?
If your lawn areas are separated by fences,
sidewalks or other objects, you may wish to
set Robomow to work in more than one zone.
Create separate zones in more than one way:
PYou may use one Perimeter Switch or one
Base Station: Connect all zones together in
one long loop of the Perimeter Wire.
The Perimeter wire can be as long as 500
meters (1650 ft) in one loop
Or :
You may set both Base Station and a Perimeter
Switch: Connect one or more zones to the Base
Station. In addition, connect other zones to a
Perimeter Switch available as an accessory for
City 120.
The Perimeter Switch may be moved from one
zone to another.
To switch zones, Robomow will be driven or
carried to the proper location.

Planning
Determining the distance between adjacent perimeter wires:
1. If lawns are installed by the same perimeter wire that is connected
to the same source (Base Station / Perimeter Switch), then it is
enough to keep a distance of one meter between the wires to prevent
interference in operation.
2. If lawns are installed using different perimeter wires that are not
connected, and each has its own source (Base Station / Perimeter
Switch), then one of the following is required:
a. Maintain a minimum distance between the wires (30-50cm) to
allow overlap between mowing zones, but synchronize between
the mowing schedules to confirm there will not be interference
between the zones. OR
b. Keep two meters between the perimeter wires with no need to
synchronize between the operation schedules.
1.2.3 Will Robomow be driving through a narrow pass in order to
move between two connected zones?
A narrow pass is part of the lawn that connects two larger zones.
The width of this pass determines how it should be set-up.
If the pass… Setup:
Is walled (fence, building, etc)
and width is More than 2.00m (6.6 ft)
OR
Edge of pass is an open area
and width is more than 1.70m (5.6 ft)
Regular setup, as Robomow can
navigate between the areas while
mowing.
(Refer to paragraph 2.1.2).
Is walled (fence, building, etc)
and width is 1.5m – 2.00m (4.9 – 6.6 ft)
OR
Edge of pass is an open area
and width is 1.1m – 1.70m (3.6 – 5.6 ft)
Set as a “Narrow Pass”: Robomow
will drive through the pass, but will
NOT get across while mowing each
area.
(Refer to paragraph 2.2.2).
Is walled (fence, building, etc)
and width is smaller than 1.5m (4.9 ft)
OR
Edge of pass is open area
and width is smaller than 1.1m (3.6 ft)
Pass is too narrow.
Set the areas as 2 separate zones.
We want Robomow to enter the narrow pass in order to move
between these zones.
But, we do not want it to cross the pass while mowing each
one of them.
See Chapter 2, Base Station and Perimeter Wire
Setup
Note: Narrow Passes require special setting of Entry
Points in order to start mowing in the adjacent areas
(see Chapter 7, Setting Robomow and using Advanced Features)
Pass wide enough. Robomow can effectively navigate
between the two areas while mowing the lawn.
Narrow Pass: Robomow will drive
through the pass, but will NOT get
across while mowing each area.

1.2.4 Are there obstacles in Robomow’s mowing path?
(Setting “Perimeter Islands”)
PObstacles such as flowerbeds, ponds, or small trees can be protected
from Robomow by setting “Perimeter Islands”.
Perimeter Islands are demarcated areas of the lawn, where Robomow
does not enter.
PObstacles that are vertical, relatively rigid and higher than 15cm (6
inches), such as trees, phone or power poles, do NOT need boundaries.
Robomow will turn when it collides with these
obstacles.
However, for the gentlest and most silent operation, you may prefer to
create Perimeter Islands around all fixed objects in the working area.
PIf areas with obstacles are grouped closely together less than 1.5m (4.9
ft), they should be demarcated by a single, continuous, Perimeter Island.

Chapter 2 Base Station and Perimeter Wire Setup
Recommendation, before you start:
During setup, you will insert pegs into the ground. To make this task
smoother, we recommend you mow your lawn and water it before starting.
Getting Ready
Confirm all parts needed for setup are within reach (refer to ‘What’s in the
Box, Introduction).
In addition, you will use the following tools:
2.1 Perimeter Wire Setup
Before you start the setup, you should have a plan for the Perimeter Wire
layout and for the location of the Base Station.
Laying the Perimeter Wire for the Internal setting of the Base Station is
different from the External setting.
2.1.1 Starting Point: Perimeter Wire at the Base Station area.
PPlace the Base Station, according to your plan, with its fence facing the
inner lawn area.
Pull the plot connector and the wire connected to it out of the plastic
covering.
Do NOT remove the wire spool from its covering.
The plastic covering is the dispenser
for the wire.
PIf setting of Base Station is Internal (inside lawn)
)Peg the beginning of the wire to the ground, where
Base Station will be located.
)Pull out 30 cm (12 inches) of wire and leave it loose at
the Base Station location.
Later, at the end of the setup this part of the wire will
close the Perimeter Wire loop.
)Start laying the wire in a counter-clockwise direction.
)Continue to pull the Perimeter Wire out of its covering,
laying it loosely as you walk along the lawn edge.

)Peg the beginning of the wire to the ground, at a distance of
1m (3.3 feet).
)Pull out 40 cm (16 inches) of wire and leave it loose at the
Base Station location. This allows for later adjustments of
the Base Station.
)Start laying the wire in a counter-clockwise direction at the
external area of the Base Station.
● Continue laying the wire for at least 30 cm (12 inch) away from
the lawn.
● Set a Narrow Pass, 20 cm (8 inches) wide, in the direction of
the lawn, until the wire is 30 cm (12 inches) inside the lawn.
)Continue to pull the Perimeter Wire out of its covering,
laying it loosely as you walk along the lawn edge.

2.1.2 Laying the Perimeter Wire
PThe Perimeter Wire is secured to the ground by the pegs supplied with
Robomow. Insert pegs every few meters and at corners.
At this early stage set a minimum number of pegs. Later, after testing
the wire setup, you will insert all necessary pegs.
PContinue laying the wire, according to your plan.
Gradually pull it out of its dispenser and lay it loosely as you are moving
in a counterclockwise direction.
PAfter uncoiling sections of wire, before inserting pegs, use the
RoboRuler to determine the distance of the wire from lawn edge or
obstacles.
If Outer Area Adjacent To Lawn… Distance Of Border From Wire

Continue uncoiling the wire, moving from the edge towards the obstacle.
Apply RoboRuler’s “Long Distance” to peg the Perimeter around the
obstacle as shown in the drawing (clockwise direction).

Caution! Setting the Perimeter Wire counter-clockwise around
the obstacle will cause Robomow to drive into the island.
PComplete bordering the island and return to the spot that
where you have left the lawn’s edge.
PThe wires leading to the Island and returning from it should be
parallel and touching.
BUT DO NOT cross them!
PPeg both wires, to and from the island, together with the
same peg.
Robomow will not recognize these two wires.
It will mow over them as if they do not exist.
Robomow will recognize the single blocking wire around the Perimeter Island
and will not enter this area.
If protected obstacles are grouped closely together, demarcate them by a
single, continuous, Perimeter Island.
If obstacles are close to the edge, leave them out of the mowing area.
2.2.2 Narrow Passes
A narrow pass is part of the lawn which connects two larger zones.
Following the Perimeter Wire, Robomow drives between these zones. But,
it does not cross the pass while mowing each one of them.
PSet the two wires parallel along the pass at a fixed distance of
30 cm (12 inches) between them (Marked on RoboRuler).
If the distance between the wires is smaller than that, the two areas should
be set as 2 separate zones.
