Dolphin Nautilus CC

The Nautilus CC is the entry model of Maytronics' Nautilus CC family, the plain corded robot that the Plus, Pro and Supreme versions build on. It suits a small, simple pool, up to 33 feet long in a rectangular or round shape, in-ground or above-ground, where the owner is happy to drop the robot in and press start before a weekend or a party.

Robot Review Desk's 2026 budget guide picks it as the safe choice among budget corded cleaners, largely because it has no lithium battery to worry about after the cordless recalls of the past few years. It is not the most capable robot here, and most expert guides skip it for the Plus model, so treat it as the option for owners who value simplicity over automation.

No battery, no charging. Every robotic pool vacuum recall in the CPSC database since 2023 (the Aiper Elite Pro, the Aiper Seagull Pro and two Wybot models in April 2026) involved a cordless model whose battery or charger could overheat. A corded robot sidesteps that failure mode entirely, and it runs at full power for the whole cycle instead of slowing as a battery drains.

Floor and walls on a fixed two-hour cycle. Maytronics lists floor-and-wall coverage, one active brush and 4,000 gallons per hour of rated suction. The Pool Nerd found good traction on plaster, vinyl and fiberglass and adequate floor cleaning, which is the job most pools need done most often.

Light and simple. At 14.8 pounds it is the lightest robot in our comparison, about six pounds lighter than the Nautilus CC Plus Wi-Fi and roughly half the weight of the Beatbot AquaSense 2 Ultra. The fine filter comes out through the top, so rinsing it does not mean flipping a wet robot on the deck. There is one button and nothing to set up.

Works in above-ground pools. Maytronics classifies it for both in-ground and above-ground pools, which the Plus Wi-Fi is not.

No timer and no app. You start every cycle by hand, and there is no way to schedule it or check on it from your phone. The Pool Nerd calls the missing weekly timer a deal breaker and gives the Nautilus CC a disapproved verdict. If you want a robot that simply runs while you are away, the Nautilus CC Plus Wi-Fi is the step up.

No swivel. The Pool Nerd lists a 50-foot cable without an anti-tangle swivel and reports tangling as a recurring nuisance. Expect to straighten the cord every few runs, especially in a round pool.

A basic filter and no waterline work. Maytronics lists waterline scrubbing as absent, and the included fine filter has no published micron rating. The Pool Nerd found the cartridges small and quick to fill, so in a leafy yard you may be rinsing them after every run.

Short warranty and limited shapes. Maytronics lists a one-year warranty and only rectangular and round pools. Kidney and freeform pools are better served by the Plus model or a cordless Beatbot, which handle any shape.

Thin evidence. Only one 2026 roundup we found names the basic Nautilus CC, so the evidence behind it is thinner than for our other picks.

Against the Nautilus CC Plus Wi-Fi, you give up the weekly timer, the app, the swivel, a second brush, the 70-micron filter, freeform-shape support and seven feet of rated pool length. You gain above-ground compatibility and a lighter robot. For most in-ground owners the Plus is worth the step up; the basic CC makes sense if you only run a robot occasionally and would rather not pay for scheduling.

Compared with a cordless robot such as the Beatbot Sora 70, the CC never needs charging but leaves a cord across the deck and skips the waterline, surface and ledges. The full ranking is in the best robot pool cleaners.

Buy the Nautilus CC if your pool is small and simple, rectangular or round and up to 33 feet, and you would rather start a light corded robot by hand than pay for a timer. Skip it if you want scheduled cleaning, have a freeform pool or want the waterline scrubbed; the Nautilus CC Plus Wi-Fi or a cordless Beatbot fits better.
