Dolphin Nautilus CC Plus review

The Dolphin Nautilus CC Plus is the non-Wi-Fi member of this Maytronics family. The exact U.S. listing identifies Product No. 99996403-PC and describes a corded, in-ground cleaner with an active brush, a top-load filter basket, a tangle-free swivel cable, and floor-and-wall coverage. The page also lists a one-year warranty. Those are manufacturer descriptions, not results from hands-on testing; this assessment uses the exact product page and its displayed comparison data.

Its clearest use is floor-and-wall maintenance

For a pool that needs the floor and walls cleaned, the CC Plus has a straightforward purpose. The formal coverage row on its product page says “Floor and Walls,” and its technical attributes explicitly say “Waterline Scrubbing: No.” That is a narrower promise than “full-surface” marketing language may suggest: the exact page does not identify a steps or sun-ledge mode. If a waterline is a must-have, this SKU should not be treated as a match. The product listing’s in-ground classification is also not a substitute for confirming pool shape, depth, finish, and other limits from current instructions.

Maytronics presents a 40-foot maximum in the product comparison row, while a separate Product & Compatibility field says “Up to 50 ft.” Those two statements conflict on the manufacturer site. For a conservative shortlist, this assessment uses 40 feet, the shorter formal comparison value, rather than promising that a pool near 50 feet is covered. A pool at the boundary deserves a direct check with Maytronics and the exact current manual before purchase.

Separate what is listed from what is unclear

The product page describes an active brush and a top-load basket, which point to a familiar cleanup routine: take the unit out after a cycle and reach the filter from above rather than opening the cleaner from underneath. The comparison table calls the main filter a Fine Filter Kit and lists an additional Ultra-Fine Filter Kit in the box. That is a useful package distinction, but it is not a particle-size rating or a promise about how the cleaner handles every kind of debris. The product page does not explain which cartridge should be used for a particular pool condition.

There is also no reliable cycle-time figure to carry into a schedule. The same listing includes a “2 hours” promotional statement and, elsewhere in the product narrative, a three-hour cleaning-cycle claim. The comparison row for this exact model leaves cycle duration blank. Rather than reconcile conflicting copy by guesswork, this assessment leaves the expected cycle time unresolved. Confirm the timing and any cycle options in model-specific instructions.

What the non-Wi-Fi version does—and does not—offer

The exact model’s comparison row says there is no mobile application. Its swivel cable may help manage cable twisting, but it does not make the cleaner cordless; plan for the power supply, cable path, and safe access to a protected outlet. The page does not establish whether a caddy or stand is supplied with Product No. 99996403-PC, so do not assume one from a photograph of another package.

There is a separate Dolphin Nautilus CC Plus w/Wi-Fi, Product No. 99996409-PCI. It is a different assessed configuration, not a wireless feature that can be inferred from “CC Plus” alone. Its exact product page lists MyDolphin Plus and a weekly timer; the ordinary CC Plus page says no mobile application. The two pages also list different main-filter labels: the 99996403-PC comparison lists Fine Filter Kit plus an additional Ultra-Fine Filter Kit, while the Wi-Fi model page labels its main filter Ultra-Fine and shows no additional filter in the box. Compare the printed suffix and package description before treating those listings as interchangeable.

Manual and pool checks matter more than the headline

The official manual portal returned no product for the exact number 99996403-PC when checked on October 29, 2026. As a result, this review does not invent an operating depth, water-chemistry range, permitted surface list, setup sequence, or repair interval from a neighboring Dolphin model. Obtain current instructions for this exact SKU before use, particularly if the pool has unusual steps, ledges, a liner, or a finish that needs special care.

Before choosing an offer, check that its carton is the single cleaner configuration marked 99996403-PC; confirm the exact warranty, which filters are actually included, the cable and power-supply contents, and whether a caddy is part of that seller’s package. The manufacturer listing gives a one-year warranty but does not settle every carton detail. If the pool is longer than 40 feet, or if waterline or app control is essential, compare a different exact model rather than relying on the conflicting 50-foot field or on a similar product name.
