Dolphin Open Box Nautilus CC review

The Dolphin Open Box Nautilus CC is a corded cleaner listing with its own U.S. product number, 66666113-USB. Maytronics’ page gives it a 33-foot pool-length ceiling, floor-and-wall coverage, a two-hour cycle, a Fine Filter Kit, and no mobile application. This is a source-based fit assessment, not a report about a particular returned machine. The linked image identifies the Nautilus CC body but does not show an open-box unit’s condition or carton.

Start with the outlet suffix, not just “Nautilus CC”

Maytronics presents this item as Open Box, distinct from the standard Nautilus CC 99996113-USB and the separately listed Refurbished Nautilus CC 88886113-US. The names share the CC platform, but these are different offer records with different condition labels. The specifications below come from the exact 66666113-USB page’s comparison row; they should not be used to identify a seller listing that omits or changes that full suffix.

The manufacturer’s Open Box description is category-level guidance: returned or lightly used units are described as like-new and inspected. That is not a condition report for a specific shipment. It does not tell you about a unit’s scuffs, prior service, missing pieces, packaging, or whether the seller’s current offer follows the same terms. The image is a clean model render, not evidence that the delivered cleaner will look untouched.

A compact two-surface job, within a 33-foot pool rating

The exact listing names floor and wall cleaning and sets the maximum pool length at 33 feet. It lists a two-hour cycle. Those fields support a straightforward floor-and-wall routine for a pool at or under the stated length, not a claim that every profile, finish, slope or step will be handled. Waterline cleaning is not listed in this product’s coverage row, and neither step support nor a minimum step depth is established. If waterline work or a shallow shelf is essential, treat that as an unanswered requirement and check another exact model’s evidence rather than extrapolating from wall climbing.

The 33-foot figure is the manufacturer’s pool-length rating—not a cable measurement or a promise about the cord’s path from a particular outlet. Maytronics’ page and image identify a corded robot, but the exact-number manual selector returned no product. Cable length, power-supply location, slack, water depth, surface limits and setup instructions therefore remain unresolved here. Measure the pool and ask the manufacturer or seller for instructions tied to 66666113-USB before relying on any layout-specific fit.

Fine filtration is listed; the extra kit is not

The page identifies a Fine Filter Kit and a top-load filtration basket. Its “Additional Filter in the Box” row is a dash, so this listing does not establish an extra Ultra-Fine kit. That distinction matters if finer debris capture is part of the reason for shopping: a separately shown filter accessory or another CC package is not proof that the open-box carton includes it. The caddy-or-stand cell is blank as well. Do not read an accessory gallery or a model photograph as confirmation of transport equipment.

The exact comparison row says the mobile application is No and the anti-tangling swivel is No. That leaves a simpler, manually started product profile than app-capable Nautilus variants, but it also means the page does not support app setup or an included swivel. A two-hour cycle is specified; a weekly timer, delay mode, automation schedule and remote functions are not established for this SKU. If one of those functions is a hard requirement, confirm the exact part number and instructions rather than treating a general product description as an operating manual.

What outlet terms can—and cannot—settle

The exact page states a one-year warranty. Maytronics’ outlet FAQ describes its general Open Box class and typical included items, but also warns that accessories can vary. Those category terms are not an inventory of this carton. Check the current listing and written seller response for the power supply, filter, instructions, exact warranty coverage and return deadline. The outlet FAQ’s return period is a published policy to verify at checkout, not a guarantee that every third-party offer follows it.

Maytronics’ separate base Nautilus CC assessment is useful only if the listing is product number 99996113-USB. The open-box page independently shows a similar core cleaning profile, but the exact code remains important for package, condition, warranty and manual checks. A bundle name, photo, or shared “CC” label does not establish interchangeable contents.

When this listing belongs on a shortlist

Keep it in consideration if a corded floor-and-wall cleaner rated for a pool no longer than 33 feet fits the task, and an outlet-class offer is acceptable after its condition and return terms are checked. Its top-access Fine Filter Kit and stated two-hour cycle are clear from the exact page; app support, waterline coverage, extra Ultra-Fine filtration, caddy inclusion, cable reach and operating limits are not.

It is a poor fit when you require a documented waterline mode, app control, a known Ultra-Fine kit in the box, or a published step-depth limit. Before ordering, compare the exact product number on the seller page and paperwork, request a current carton list, and confirm the warranty and return path in writing. The manual gap is material: this review does not transfer setup or safety instructions from the new or refurbished CC listings. That is the practical boundary of the available evidence.
