High pressure filtered water is pushed from the Booster Pump through the supply line,
through the wall fitting and strainer, through the feed hose to the Jet-Vac. Some of the
water is directed to the sweep hose before entering the Jet-Vac head. Water enters
the Jet-Vac head and half is directed to the upward facing venturi jet, shooting water
up into the bag and drawing in dirt and leaves. The other half is directed into either the
Forwarding Pusher Jet to propel the cleaner forward or the Reversing Jets to make the
cleaner reverse.
What makes my Jet‑Vac go forward
or reverse?
There are ports and channels inside the white
bottom plate.
Forward: When the forwarding port is open, the
water is directed to the JV17 Pusher Jet Nozzle,
providing the propulsion to push the Jet-Vac forward.
Reverse: The reversing port is divided into two
segments. At the start of the reversing cycle, water
is directed to the left side reversing jet, making the
Jet-Vac reverse and rotate anti-clockwise. When the
reversing port is fully open, equal amounts of water
will be directed to the left and right reversing ports,
allowing the Jet-Vac to reverse in a straight line.
At the end of the reversing cycle, water is directed
to the right side reversing jet, making the Jet-Vac
reverse and rotate clockwise. The continual reversing
and rotating of the Jet-Vac ensures the cleaner
will not get caught or snagged in any spot for a
significant length of time.
Check the correct operation of the gearbox by
holding the Jet-Vac out of water whilst operating.
Watch the correct cycling of the water flow as
described above.
Hint: Hold the cleaner upside down at water level
to gain the best view. Hold the sweep hose from
spraying everywhere.
What opens and closes the ports?
The bottom JV7 Gear is the active gear in closing
and opening the forwarding and reversing ports.
The series of holes in the gears ensures that the
forwarding port and the reversing ports cannot open
at the same time or be closed at the same time. High
pressure water enters the Jet-Vac head and spins
the JV8 Propellor. The propellor engages the gears
so that the bottom (active) gear moves the slowest.
When the hole in the active gear lines up with a port,
then water is directed through that port.

How does my Jet-Vac work?
AUTOMATIC
POOL CLEANER
How long does my Jet‑Vac go
forward or reverse?
Jet-Vac moves forward for approximately 3 minutes,
then moves into its reversing mode. The reversing
and rotating cycle lasts for approximately 45
seconds.
Summary:
The venturi port always remains open, so that the
Jet-Vac is always picking up debris regardless of
whether it is in forward or reverse mode. No other
pressure cleaner has this feature. When the Jet-Vac
is in forward mode, no water should be exiting from
the reversing jets. Likewise, when the Jet-Vac is in
reverse mode, no water should be exiting the JV17
Pusher Jet Nozzle. This patented system is the most
advanced, proven and reliable water management
system available today.
Propulsion:
Jet-Vac is propelled purely by water pressure.
Jet-Vac does not need turbines, drive chains or belts.
Cleaning Action:
Jet-Vac picks up debris by using a venturi jet
of water.
The Result:
Advanced yet simplistic design that requires fewer
moving parts, resulting in a reliable and robust
automatic pool cleaning system.
