No micron figure is published for its filter kit
No caddy is listed in the base package

The two lists above come from the maker’s own specifications and this site’s arithmetic on them, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.

What owners say

One buyer ordered the CC Pro for its basket and waterline scrub, and an owner who runs it about daily loves the basket. The recurring practical question is filters: owners say it comes with the fine mesh kit, and they trade part numbers for the ultra-fine sets that fit.

Reliability reports are mixed. Some owners are two or three seasons in and happy, while two new units would not run properly at first and three owners name the power supply. Warranty help split in 2025: one owner got a new control unit after one call, another says sending the robot in takes weeks at the owner's shipping cost, and a third could not reach a person and reversed the charge.

Its catalog row casts it as the Nautilus that adds a waterline scrub and a 50-foot rating, rated for above-ground pools as well. Owners who want fine debris caught add ultra-fine filters, and two run it daily or almost daily through summer.

What owners like

One buyer ordered it for the basket and the waterline scrub, one owner who runs it about daily loves the basket, and two owners swap in an ultra-fine filter once the pool is already clear.
It takes Dolphin's ultra-fine filters: one owner says the official 9991467-R4 set fits and catches far more debris than the basic filters, and another says the genuine set they bought in 2023 fits too.
Owners are pleased with it: one who switched from an old Hayward Navigator calls it a definite upgrade, one says it perfectly cleans a pool that gets lots of leaves, worms and pine needles, and one would buy another despite a failed control unit.

Common complaints

Ultra-fine filters are an extra: owners say theirs came with the fine mesh kit only, two paid about $100 for a genuine set in 2023 and 2025, and two had trouble confirming which would fit.
Reliability complaints from 2025 include a brand-new unit that moved six inches, stopped and errored out until its owner found a loose wire, and a power supply that failed in year one and gave connection trouble in year two.
One otherwise happy owner rated the app as mediocre and manual drive as clunky in 2023, since steering it to the waterline for pickup meant starting a cleaning session, driving, then cancelling.
One owner found bits of their pebble finish in the canister and worried the robot was wearing the surface, though they put the finish at 10 to 15 years old.
Leaves and twigs reach the impeller for two owners: one can rarely manage two or three runs before it clogs, and another finds pine needles inside the body, blowing out the top vent, and is unsure if a part is missing.

Questions owners ask about the Dolphin Nautilus CC Pro

Which ultra-fine filters fit the Nautilus CC Pro?

One owner runs the official Dolphin 9991467-R4 filters and confirmed from order history that they fit. In 2023 Maytronics support gave another owner part number 9991467-ASSY, saying the Active 30 takes the same filters, and the genuine set that owner bought fits. One owner who asked Maytronics' chat for ultra-fine filters under warranty was sent another fine mesh filter instead.

CC Plus or CC Pro?

Its catalog row gives the CC Pro the waterline scrub the CC Plus lacks, a 50-foot rating, and an above-ground rating the CC Plus does not have. One buyer ordered it for the basket and the waterline, one owner contrasts its basket with cartridges, and another advises paying extra for the Pro, having found it on sale for less than the base CC in 2025.

What fails on a CC Pro?

In 2025 owner accounts the power supply is the part named most: one failed in the first year and was replaced under warranty, one owner got a new control unit after a single call, and one stopped powering on after an update. A brand-new unit errored out until its owner reseated a loose wire, and one used on a service route had its drive motor jam the gear.
