5. USING THE POOL CLEANER
The Pool Cleaner is very simple to use. Simply put it into the pool and make sure that it is properly
sitting on the floor of the pool. Turn it ON and let it get the job done.
5.1 Setup
Before using the Pool Cleaner for the first time perform the following steps:
Unwind the cable and stretch it out completely so that it has no kinks.
Some models arrive with plastic coverings on the brushes.
Remove them before use.
Adjusting the handle angle
The robot’s handle should be adjusted and locked diagonally in order to ensure optimum cleaning
results.
The handle angle can be adjusted also to determine the speed at which the robot advances along
the water-line.
To adjust the handle angle:
A. Press the latch down and hold it in position.
B. Move the handle to the desired position and release the latch to hold the handle in place.

Position the power supply so that it is approximately in the middle of the long side of the pool at a
distance of min 3.5m/12ft from the pool and placed 11cm/4'' above ground.
Attach the floating cable to the power supply by inserting it with the notch on the connector (1)
lined up with the groove in the socket on the power supply and turning clockwise (2).
Plug in the power supply and leave it in the OFF position.
5.2 Putting the Pool Cleaner into the pool
If your Pool Cleaner is equipped with brushes that
contain sponges, dip the brushes in the water and
squeeze them so that they will absorb water the
first time you use the Pool Cleaner, or if the brushes
have dried out between uses.
Release the Pool Cleaner and let it sink to the floor
of the pool.
Make sure that the floating cable is free of any
obstructions.
To avoid kinks in the floating cable, place
approximately enough cable in the water for the
Pool Cleaner to reach the farthest corner of the
pool.
Net filter
