Dolphin Nautilus CC Supreme review

The Dolphin Nautilus CC Supreme (Product No. 99991083-PC; UPC 850015249051) is the Nautilus configuration in this group with three brushes and two listed cycle durations. Maytronics specifies floor, wall, and waterline coverage for in-ground pools up to 50 feet, alongside MyDolphin Plus scheduling and an extra Ultra-Fine Filter Kit in the box. The review below is an evidence-based reading of the exact U.S. listing, not a hands-on test. Some setup questions remain unanswered because the manufacturer’s exact-number manual portal returned no product.

Waterline reach is its clearest fit distinction

The exact specification table lists floor, wall, and waterline scrubbing and a 50-foot maximum pool length. The pool classification is in-ground; the table names rectangular, round, free-form, and kidney shapes. That is broader than the standard Nautilus CC’s listed floor-and-wall task, but it is not a guarantee that the Supreme handles every step, bench, sun shelf, finish, or wall transition. The product page provides no step-specific depth condition. If an unusual feature is the reason you are shopping, ask Maytronics about that exact pool feature instead of inferring it from the words “waterline” or “all pool shapes.”

The machine is corded: the exact listing names an anti-tangling swivel cable, and the manufacturer product record does not mark it cordless. No cable-length figure appears in the reviewed technical table, so do not use the 50-foot pool rating as a cable measurement.

Two cycle choices and an app scheduler

Maytronics lists 1.5- and 2.5-hour cycle durations, with 2.5 hours shown as the default. The same table says MyDolphin Plus, a weekly timer, an enabled delay feature, and automation mode. These entries give the Supreme more scheduling flexibility on paper than a cleaner with just one listed two-hour routine and no app. They are manufacturer-published settings, not measured cleaning times or a promise that each pool will be clean after one cycle.

The listing describes control from the app and gives Wi-Fi connectivity, but it does not document every control sequence in a model-specific manual result. Confirm app compatibility and the exact setup steps for your controller, network, and phone before counting on remote operation. It also lists no remote control as a separate attribute; that is not evidence against the documented app connection.

Filter kit and brush details

The Supreme’s formal table names a Fine Filter Kit as the main filter type and lists an additional Ultra-Fine Filter Kit in the box. Access is from the top. The listing does not state a micron value in its filter fields. Its descriptive copy mentions the ultra-fine upgrade, but the safest package interpretation is the exact table: a main fine kit and an additional ultra-fine kit for SKU 99991083-PC. Confirm both are in the seller’s carton, especially when the offer title includes a caddy, cover, or another bundle description.

Three brushes are listed, with Standard and Combine brush types, and the active-brush field is Yes. The page’s 24.63-pound robot weight is useful for planning storage and lifting, although it does not predict how heavy the unit will feel when wet. A top-access cartridge may be convenient for above-unit removal, but no first-hand maintenance experience is claimed here. Follow the correct instructions for rinsing and re-seating the filter.

How it differs from CC Pro and Titan

The CC Pro is also listed for floor, walls, and waterline up to 50 feet and supports MyDolphin Plus, but its exact table lists two standard brushes, a Fine Filter Kit, and no additional ultra-fine kit. The Supreme adds a third brush, the extra ultra-fine kit, and its 1.5-hour option; it also has a delay feature. The Titan shares a 50-foot waterline/app profile and an added ultra-fine kit, but its main filter is labeled Combine, it has two brushes, and it is the one in this group whose page describes Pick-Up Mode. Those distinctions belong to their separate SKUs, not to the Nautilus name as a whole.

Compared with the simpler Nautilus CC, the Supreme adds waterline coverage, app scheduling, a swivel, and more filtering and brush choices, but the manual gap still limits certainty about operating constraints. The specification page gives a one-year warranty. The comparison table’s caddy/stand field is blank, so do not treat the product image or a nearby package option as evidence of included storage equipment.

Check which caddy package is actually offered

Maytronics separately lists Nautilus CC Supreme packages NAUT-SUP-CAD and NAUT-SUP-CADCOV. Their offer names distinguish a caddy from a caddy with its protective cover; neither package name is evidence that base Product No. 99991083-PC includes those storage accessories. The direct exact-number manual searches for both package IDs returned no products, so current setup instructions remain unverified for those cartons. Treat the package difference as an add-on to the same cleaner assessment only for the named caddy/cover contents; confirm the exact item number, carton contents, operating instructions, and warranty with the seller.

Buy only after the exact listing is checked

The product page identifies an in-ground configuration, four pool shapes, a 50-foot length ceiling, and a one-year warranty. It does not resolve water depth, surface restrictions, safe power-supply placement, cable care, or detailed pool-chemistry guidance. The exact-number manual portal returned no document for 99991083-PC; family-level directions should not be assumed to match without confirmation. A previous exact-string screen of the CPSC all-recalls CSV (retrieved October 29, 2026) found no match for this SKU, UPC, or model name, but it is not a safety clearance.

This cleaner deserves consideration if in-ground floor, wall, and waterline coverage plus app scheduling, selectable cycle durations, and an added ultra-fine kit are essential. It is less compelling if an exact manual, documented step cleaning, a known cable length, or a confirmed caddy package is a prerequisite. Ask the seller to identify Product No. 99991083-PC on the carton and confirm the included filter kits, controller, warranty, and exact current instructions before purchase.
