Low vacuum or slow,
faltering hammering sound:
• Check large debris isn’t blocking
your hose or VTX-C (see page 17).
• Check the Smart-Skim or Auto
Skim valve and vacuum plate
is sitting correctly in the
skimmer box. You may need a
different adapter for the Smart-
Skim.
• Backwash filter.
• If you have more than one
skimmer box, you’ll need to block
off water flow from the box not
connected to the VTX-C.
• Check if the inlet from the
main drain is leaking, install an
expanding plug.
• Your pool pump and filter system
may be too small to effectively
run your VTX-C. Ask your pool
professional for advice.
• Check for leaks or small holes in
the main body.
• Check flow valve for damage.
• Check if the hose is damaged and
replace damaged section with a
new length of sectional hose. Some
damage can be visually inspected
or a hissing sound can be heard
coming from the hose when raised
out of the water and the pump is
on.
VTX-C stays at one end of
the pool:
• Check that the hose is long enough
to reach the far corner of the pool.
If it isn’t, add extra sections.
• Check that the hose isn’t kinked or
coiled (see page 16).
• Check that the pool outlets aren’t
pushing the VTX-C off course.
Adjust downwards if necessary or
use an eyeball diverter.
• Do you have enough pool weights
on the hose? Additional weights
may improve directional stability.
• Check your hose isn’t too long.
Try removing one length.
VTX-C only travels around
the water line:
• Check the hose is not coiled. If it is
coiled, try to straighten the hose out
(see page 16).
VTX-C travels around the water
line in only one direction:
