ABOUT THIS PRODUCT
Thank you for choosing the LawnMaster
®
VBRM601YCM robotic lawn mower. This mower will
independently mow the lawn in a random pattern without the use of a boundary wire and charging
station and will operate during daylight hours only. The mower detects grass in order to know where
to mow, and is also equipped with ultrasonic sensors which detect higher obstacles such as shrubs
and fences. For successful operation, the lawn must be dened with at borders such as paving, or
raised edges. When the mower does not detect grass or encounters an obstacle, it changes route in
a random manner and starts mowing again in a new direction. The mower can be moved around to
different lawn areas provided that they are dened as described in this instruction manual.
The mower uses a detachable MX 24V battery which is compatible with all products in the
LawnMaster
®
24V range. It is designed to be used once or twice a week for several hours, and then
stored away in a garage or shed until it is needed again. It will mow approximately 1076 sq. ft /
0.025 acres (100 m
2
) on a single charge depending on lawn conditions. Excessively long or wet grass
may impact performance, it is therefore important to maintain a regular mowing schedule to keep on
top of growth and develop a neat lawn nish.
The noise emission declarations conforms to EN 50636-2-107:2015
Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC directive
2000/14/EC. The guaranteed sound power level includes variation in production as well as variation
from the test code with 1-3 dB(A).
Sound pressure noise uncertainties KpA, 2-4 dB (A)
FIRST OPERATION
The VBRM601YCM is designed to detect grass and move into areas it identies as grass. If it cannot
see a clear boundary it will continue to move into areas off the lawn and into plants that it may identify
as grass. Trimming the lawn edge with a grass trimmer before use will help define a better lawn
edge. During rst operation on a new lawn it is important to monitor the robot as it detects edges to
see where the boundary denition needs to be improved. Please do read the instructions fully; our
instructions have been written to help you to get the best results and also provides useful ideas for
temporary boundaries as well as examples of how to dene a better lawn edge in all seasons.
FOR YOUR SAFETY: CAREFULLY READ AND UNDERSTAND ALL INSTRUCTIONS.

PREPARING THE MOWING AREA
Lawn Surface
1. The lawn surface should be as uniform as possible. Bare patches and leaves can disrupt the
operation of the mower. Clear leaves at regular intervals and repair dead patches with grass seed
2. Inspect the lawn for holes or hollows. Fill them with topsoil to prevent rainwater from forming pools
of water on the lawn and to prevent mower from becoming stuck. The mower may be damaged if it
is operated in pools of water (Fig. 5).
3. If there are stones on the lawn that may damage the mower, they should be removed or excluded
from the working area (Fig. 6).
NOTE:
This mower is not designed to cut excessively long or overgrown and neglected areas. For
best performance mow or trim grass down to 2.36'' (60 mm) before use. Do not allow grass to grow
excessively long between uses.
DEFINING THE MOWING AREA
Lawn edges must be clearly dened by at edging or raised barriers in order for this mower to function
properly.
1. Visual boundaries need to look different from lawn, therefore changes in color and texture are very
effective.
2. Physical boundaries help stop the mower, when a visual boundary is not possible.
3. Temporary physical boundaries can be used while the lawn boundary denition is improved.
The robotic mower is equipped with the following devices which allow it to detect the edges and know
where to mow:
• The lawn detection camera: for recognizing changes in surface type, e.g., from lawn to paving.
• Two ultrasonic object sensors: for detecting the obstacles higher than 9.84'' (25 cm). They are
turned on by default setting and will sense plants, shrubs and other obstacles in and around
the edges of the lawn. For a consistent cut, long grass must be cut down before mowing, or the
ultrasonic sensors must be turned off.
The ultrasonic sensors can be turned off when the lawn to be mowed is clear of obstacles. In this case,
hedges, walls, or other similar barriers in the lawn can be used as the border of the working area.
When the robotic mower detects that there is no lawn or encounters an obstacle, it changes route in
a random manner and starts mowing again in a new direction. To allow the robotic mower to move
freely inside the lawn, the lawn must be properly checked and adjusted so that the robotic mower has
enough space for recognizing when there is no grass. Carefully follow instructions listed as below for
types of borders/protections that can/cannot be used for dening the working area.
OPERATION
Fig. 5
Fig. 6
21
OPERATION
Paving
The lawn requires a paved or wooden edge of at least 13.78'' (35 cm) wide for it to stop safely and
change direction.
Paving or wooden edge less than 13.78'' (35 cm) wide must be widened, or can be used in conjunction
with a barrier. See Raised Barrier section below (Fig. 7).
Raised Barrier
With the ultrasonic sensors on, a perimeter barrier at a height above 9.84'' (25 cm) can be used to
dene the border of the working area.
If an existing barrier is shorter than 9.84'' (25 cm), replace or raise the barrier or add additional paving
(Fig. 8).
Hedging
With the ultrasonic sensors on, hedges can be used to dene working area (Fig. 9).
NOTE:
Foliage is usually recognized as grass by the robotic mower. Therefore, ultrasonic sensors
must be always kept on when using hedges as the border of the working area.

Fine gravel
If ne gravel or small stones are used to border the lawn, make sure the width of the border is more
than 13.78'' (35 cm) wide and has clear edges (Fig. 10).
NOTE:
Never use gravel, stones or similar materials with irregular edges for dening the working area
(Fig. 11). Failure to provide clear edges will result in the mower leaving the mowing area and blade
damage.
Physical Bump Barriers
A border that physically obstructs the movement of the mower can also be used. This boundary could
be lower than 9.84'' (25 cm) so undetectable by the ultrasonic object sensors, and also narrower than
13.78'' (35 cm). When the robot meets this physical barrier, it will bump off, reverse and turn. This type
of boundary may suit your lawn in some areas.
Temporary Physical Bump Barriers
During rst use, while lawn patches are being seeded or with seasonal lawn owers, it may be
desirable to use a temporary method to protect or dene the lawn area for the mower to cut. In this
case, garden canes are particularly effective and do not detract from the look of the lawn. In spring,
you can protect ower bulbs in the lawn from the mower by sinking short canes vertically into the lawn
around the area spaced at 7.87'' (20 cm). The mower will be physically prevented from entering any
protected areas.
Magnetic Strip
The magnetic strip serves as a mobile and temporary boundary for creating areas where the robotic
mower is not allowed to mow.
The robotic mower is equipped with a magnetic strip sensor for recognizing a magnetic strip lying on
the ground. When the robotic mower comes across a magnetic strip, it will stop and begin to mow
again in a random direction.
1. Lay the magnetic strip a few centimeters away from the area or object in question.
2. Keep a distance of at least 47.24’’ (120 cm) between two independent boundary areas made up of
OPERATION

magnetic strips, so that the robotic mower can travel through without difculty (Fig. 12).
3. Make sure that the outer boundary of the mowing area is dened by an optical or physical
separation.
4. Fasten the magnetic strip to the ground with the supplied magnetic strip pegs spaced 39.37'' (1 m)
apart.
Obstacles in the Mowing Area
With the ultrasonic sensors on, objects which do not impede the robotic mower’s normal functioning,
such as trees (without raised roots), vertical poles, etc., do not require excluding from the mowing area
(Fig. 13).
When objects, such as exposed tree roots, exposed wires, irrigation systems, drains, etc., are present
on the surface of the lawn, it is required to protect these objects with paving, walls or barriers to
prevent the damage to them and to the robotic mower (Fig. 14).
The working area cannot be dened by holes or ditches. Ensure that there are no objects such as
toys, work tools, small stones, branches, or sprinklers, etc., on the lawn or protruding from the ground
which could impede the mower or cause damage to the blade (Fig. 15).
NOTE:
Avoid leaves accumulating on the lawn, as they may not be detected correctly by the robotic
mower. Remove leaves at regular intervals.

Slopes
The robotic mower has the ability to safely climb slopes of 35% or 20º inclines, and areas that are
steeper than this should be excluded (Fig. 16).
To calculate the slope of your lawn, see Fig. 16. The slope would be:
Pools and Ponds
If there is a pool or pond in the mowing area, create appropriate borders to protect it.
- Raised barriers higher than 7.87'' (20 cm).
- Flat edging (paving, gravel or wooden boards wider than 27.56'' (70 cm)).
The illustration shows a correctly dened working area for the correct functioning of the mower (Fig. 17).
It is very important to make visual boundaries around ponds wide and obvious for the mower.
Pond plants and algae could be interpreted as grass. Physical boundaries around ponds are
highly recommended and will prevent any accidental water damage to your mower which is not
covered by the manufacturers warranty.

29
2. Spiral Cutting
In Spiral cutting mode, the robotic mower will mow in a spiral outwards from where it is placed on the
lawn. This is best used to tidy up any areas that may not have been mowed during a random mowing
session.
After the robotic mower is powered on, press the Spiral button for 1 second followed by the START/ON
button. The mower will rst move forward about 3.94'' (10 cm) to 7.87'' (20 cm), then start Spiral cutting
covering approximately 21.53 sq. ft (2 m
2
). After the Spiral cut is nished, the robotic mower will start to
mow in a random pattern automatically.
If the area to be mowed is too narrow for the robotic mower to carry out the spiral cut, after continuous
searching, the mower will mow in a random pattern automatically.
NOTE:
Spiral cutting is also a great feature to use before random mowing to systematically and
efciently cut the main areas of the lawn, by doing this it reduces the amount of random cutting time
needed to complete the lawn. You also get a better lawn nish.
SETTING THE CUTTING HEIGHT
Do not make any adjustment to the robotic mower without rst stopping the motor. Keep your feet
away from the blade disc when adjusting its height.
The cutting height of the mower can be adjusted from MIN 1'' (25 mm) to MAX 2.5'' (65 mm) (Fig. 19).
During the rst weeks of mowing, always select the higher cutting height 1.5'' (40 mm). After this, the
cutting height can be lowered step by step every week until the desired cutting height has been reached.
1. Press the STOP button to stop the robotic mower.
2. Turn the cutting height adjustment knob to set the cutting height.
- Turn clockwise to raise the cutting height.
- Turn counter clockwise to lower the cutting height.
3. For the rst cut each season, a higher cutting setting should be selected.
USING A CUTTING
HEIGHT THAT IS TOO LOW IN LONGER GRASS WILL USE MORE POWER AND REDUCE
BATTERY RUN TIME.
4. Before you begin to mow, check to ensure that the blade is not blunt and that none of the fasteners
are damaged. To prevent any imbalance, replace blunt and/or damaged blades. To carry out this
check, rst switch off the mower by removing the safety key.
