Troubleshooting

Solution
• Backwash and clean filter. Empty all baskets.
• Clear debris from oscillator or hose.
• If hoses from skimmer to filter and back to pool are less than
1-1/2"diameter, replace with 1-1/2"hoses.
• Pump in filtration system may be too small. Consult pool
professional.
• If your pool has a main drain (floor drain), close it during
cleaner operation.
• Make sure vacuum regulator is installed.
• Set brush ring adjuster to a higher number.
• Hose is too short. It should be approximately 5-8' longer than
the full length of the pool. Buy an extension hose from your
dealer to give adequate length.
• Set brush ring adjuster to a lower number.
• Make sure vacuum regulator is installed.
(the regulator marked "50" will slow it the most).
• If your system has a return valve, gradually close it until
oscillator runs at the desired speed.
• For best results, when hose is not in use, store it flat and straight.
• Lay hose out in the sun (flat and straight) for a few hours.
• Hose is too long; remove 8' section
• Any cleaner may miss a spot. Spot clean pool by attaching a
vac-pole (telepole) to cleaner and steering it (see Page 6).
• Try different brush ring adjuster settings (0-4) until the cleaner
gives the desired results.
• The cleaner was not designed to work under all solar covers.
• Strong winds may interfere with complete cleaner coverage.
• This is normal if filter system develops a backpressure surge
when the pump stops. The cleaner will right itself when system
is restarted.
• Use reducer cone in skimmer.
• Install diaphragm marked "50" in vacuum regulator.
• Check inner brush ring for excessive wear.
