Fine Tuning The Cleaner
When operating correctly, the cleaner vacuums, sweeps and scrubs all surfaces randomly
throughout the pool. Approximately every three (3) minutes the cleaner goes into back-up mode.
This action pulls the cleaner away from pool obstacles and increases its random pattern.
Thrust Jet Adjustment
The thrust jet powers the direction of
the cleaner. Factory position is seven
(7) o'clock but, depending on the
pool, other settings can be helpful to
improve cleaner coverage.
Sweep Hose Adjustment
The sweep hose should move in a
gentle sweeping motion. To adjust
the motion, turn off the booster pump
and turn the sweep jet clockwise
to increase or counter-clockwise to
decrease the movement.

Routine Maintenance

Cleaning the Bag
To remove the bag, detach the velcro
strips. Twist the bag collar and pull up to
free the bag from the cleaner. Unzip both
sides of the bag to remove the debris.
Empty the filter bag when it is
half full, especially if the debris
load is sand.
It is easier to empty the filter
bag when it is dry. Alternate
between two (2) bags.
