Polaris Issues - sluggish

My Polaris Sport is sluggish and is getting stuck in corners all the time. The internals have been rebuilt, the backup acorn is working fine but underpowered.

Overall it moves at a very slow pace, not like normal.

I’ve tried the connection to pool with without reducer.

Can’t figure this one out.

From my polaris manual

For proper operation, the wheel RPM should be
between 28 and 32.

If the Polaris is operating below 28 RPM:
• Remove the universal wall fitting by
attaching the quick disconnect. Pull it
away from the pool wall as you unscrew
the universal wall fitting.
• Push the blue restrictor out of the universal
wall fitting.
• Reinstall the universal wall fitting.
• Recheck the wheel RPM.
If you still have less than 28 RPM:
• Clean the filter screen in the quick disconnect. A dirty filter screen will restrict the
water flow from the pump to the Polaris.
• Check the hoses, connections, and swivels
for leaks that could cause loss of water
• If there is a gate valve installed on the
booster pump or the Polaris cleaner line,
open it completely so water can flow freely
to the Polaris.
• Clean the skimmer and pump baskets.

work, contact our Customer Service Department

also check your wheels, mine get slick and have no grip and then get stuck.
