Introduction
Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to
always take some basic safety precautions when using this product. Please read this operating manual
carefully and make sure that you understand it.
Keep these operation instructions in a safe place.
Safety instructions
•This model is especially suitable for pools with flat floor; follow the corresponding instructions in
this manual if your pool has a sloped floor.
•To avoid serious damage to your robot, never switch the device on when it is not in the pool.
•The power cable must be connected to an appropriate earthed socket. Only operate the device
with a residual current protective device with a triggering amperage of max. 30 mA.
•Do not operate the robot while persons are in the pool.
•Do not try to move the floating bodies alongside the power cable. Always leave them at their
initial positions.
•Before switching the device on, make sure that the cable is completely unrolled to avoid any
rolling-up of the cable which would impair the efficiency of the robot or damage it.
•The filter bag must be cleaned before or after each use. This avoids that contaminations of the
filter bag impairs the normal operation if the robot.
•When not in use, the robot must be stored in a cool and well-ventilated place and not in direct
sunlight.
•The power-supply unit must be place in a shadowy place. To avoid any overheating and possi-
ble consequential damage of components, never cover the power-supply unit.
•The robot and motor unit should only be opened and/or repaired by qualified persons.
•To avoid any accidents or damages, the power-supply unit should be placed at a min. distance
of 3.5 m from the edge of the pool.
•Do not use the device in other working conditions than those stated in this manual. Only use
the device according to the intended use defined in this manual.
•Do not remove the protective film of the control panel.
•Close the pool filter system when you use the robot.
Other instructions
•Placing the robot in the pool and removing it from the pool should be so that the wheels of the
robot point towards the walls to avoid that the surface of the pool be scratched.
•Store the cleaning robot on a flat surface. No hard objects must touch the casing of the robot to
avoid damage.

Function and adjustment of nozzles
The robot has two nozzles, one of which opens when the other closes. Water flows through the opening
nozzle to move the cleaning robot forward. The user can change the orientation of the nozzle by turning
it to control the track that the robot takes.
Adjustment of nozzle, speed, and track
•In general, cleaning is more efficient when the robot runs more slowly.
•The larger the curve described by the track, the less the cable is twisted.
Overlapping tracks and different settings of the nozzles
Low speed
Adjust with symbol (see fig.)
High speed
Adjust with symbol (see fig.)
The user can select the appropriate nozzle orientation for different pool types, e.g., a low speed with a
large radius of movement, by setting the circle symbol 〇to the 45° position (movement to the left) or
75° position (movement to the right).

Nozzle adjustments
•In most cases, the same orientation of both nozzles is suitable for every pool shape.
•A curved and direct track alternate if one of the nozzles is set to 30° and the other to 60°; this
will permit that a very large portion of the floor be covered, and it will help to release any cable
twists.
Distance adjustment
•On the control panel, select a suitable pool distance according to the pool width.
•It is recommended to select a larger distance if the nozzle is set to a low speed or if your pool
is sloped. With a pool of 6 m of width, it is recommended to select an 8 m or 10 m distance if
the robot is to run slowly.
Sloped pool adjustments
Set the nozzle to a high speed, so that the robot can cope with the slope, by reinforcing the water flow
rate of the robot (see fig. concerning high speed).
Note! With some pool shapes, it cannot be guaranteed that the cleaning robot can cover the entire
surface of the floor. You can adapt the nozzle orientation to reduce the moving curve ; however, that
means that the cable will be twist more often.

Depending on pool size
Note! The above-mentioned values are recommendations. The user must adapt the suitable nozzle
orientation considering the above-mentioned procedure and the actual pool.
Placing the cleaning robot into the water
1. With one hand, hold the cable, making sure that there is enough cable between your hand and
the robot that the device can plunge into the water without however touching the floor. With the
other hand, hold the handle of the cleaning robot and slowly place the device into the water.
2. Hold the cable until the robot has filled itself with water and begins to sink towards the floor.
3. By obeying the above procedure, you will avoid that the cleaning robot tip over.

Helpful hints
•Unplug the plug after use. However, do not plug it out with your hands being wet.
•The cleaning robot should not touch de pool walls when you take it out of the water to avoid that
the surface of the pool be scratched or the robot be damaged.
•Before taking the robot out and placing it on the edge of the pool, hold it above the water surface
during approx. 10–15 s to allow the water remaining inside the casing to drain off.
•Hold the robot at the handle to take it out of the pool.
