Correctly Operating Cleaner
11
Use Only Genuine Hayward Replacement Parts.
Movement
When the Viio cleaner is operating properly, it will
randomly travel around the bottom of the pool.
Spin-Out
Viio will periodically stop and rotate clockwise in order
to provide better pool coverage and to escape from
corners and other obstacles. If the cleaner is
momentarily stopped in a corner or at an obstacle, it
will Spin-Out to free itself and continue moving
randomly about the pool. The Spin-Out Cam determines
the frequency of the Spin-Outs. The cleaner comes
equipped with 3 Spin-Out Cams; every 75, 50 (factory
installed) or 30 seconds (75 second and 30 second
Cams are in the Accessory bag). To change Spin-Out
Frequency see “Changing Spin-Out Cam”.
Sweep Hose
The Sweep Hose should move in a slow, undulating
(snake-like) motion. It moves debris out of tight corners
so the cleaner can vacuum the debris at a more
accessible spot in the pool. The Sweep Hose also stirs
fine debris into suspension for removal by the pool’s
filtration system.
The Sweep Hose Rollers are wear
parts
. When the rollers wear-down to the outer groove
(Wear Line) replace the Wear Rollers (P/N AEX5006A) a
bag of extra Wear Rollers is included. If a hole forms in
the Sweep Hose, it must be replaced with a genuine
Hayward Sweep Hose. (See Item 23 on page 18.)
Cleaning
When Viio is on the bottom or walls debris is vacuumed
from below the cleaner and passed through the vacuum
tube into the Debris Bag, where it is held until the user
empties the Bag. Viio may not pick-up all debris on the
first pass, but your pool should be clean in 3-hours or
less (depending on pool size, shape and the amount of
debris in the pool).
Observe Viio’s operation at regular intervals and
empty the bag as necessary.
Only operate Viio for the
time necessary to clean the pool. Excessive use is
unnecessary and will cause premature cleaner wear.
Fine Debris
The Large Capacity Debris Bag, as with other pressure-
side cleaners, does not hold very fine sand or other
powder-like debris. Powder will be blown through the
bag and into suspension so it can be filtered by the
pool’s filtration system.
Sand (Dense Debris)
Always empty the Viio bag when sand (or heavy debris)
fills the bag up to the blue “EMPTY SANDLINE”.
Pools with excessive amounts of sand should be
manually vacumed before installing Viio. Viio is designed
to operate with 1 cup of sand and the remainder of its
bag filled with leaves, acorns, grasses, etc.
Pressure Hose
This hose has been designed to minimize the forming of
loops and knotting. Most of the pressure hose should
remain below the surface of the water the majority of
the time. If the hose forms a loop the cleaner will
eventually work it out. In the rare event the hose
becomes knotted or tangled, it will limit the range of the
cleaner. To get optimal coverage, remove knots or bad
tangles if found.
