The Dolphin Nautilus CC Plus is a corded robot pool cleaner that scrubs the floor and walls of in-ground pools in about two hours. It suits owners who would rather manage a cable than a battery, and it was Bob Vila's best overall pick. It does not scrub the waterline and has no app, so most buyers who want a modern cordless robot should look at newer models first.
What the Dolphin Nautilus CC Plus is
The Nautilus CC Plus is a robotic pool cleaner from Maytronics, the maker of Dolphin robots. It runs on a 60 foot cable connected to a power supply beside the pool, so there is no battery to charge or replace Maytronics ↗. It cleans the floor and walls of in-ground pools up to 40 feet long, in rectangular, free form and kidney shapes Maytronics ↗.
The robot weighs about 20.8 pounds Maytronics ↗. Its default cycle is 2 hours, and a weekly timer lets it run on a schedule without you lifting it in and out each time Maytronics ↗. Hands on testing is in progress. This review is based on the maker's page, a retailer listing and Bob Vila's hands on test.
What it does well
It is simple to own. You plug it in and drop it in the pool, and there is no booster pump to install Maytronics ↗ Poolbots listing ↗. Because it is corded, it never stops mid cycle on a flat battery, and there is no battery that loses capacity after a few seasons.
It climbs walls. Bob Vila praised its wall climbing and noted that it reverses at the top of the wall Bob Vila guide ↗. Two combination brushes scrub as it goes, and Maytronics rates its suction at 4,500 gallons per hour Maytronics ↗. Bob Vila also found it works on all pool floor types Bob Vila guide ↗.
The filter is easy to reach. A top load fine filter lifts out for rinsing, and Bob Vila said the large filter basket handles sticks and leaves Maytronics ↗ Bob Vila guide ↗.
An anti tangle swivel keeps the cable from twisting as the robot turns Maytronics ↗. Bob Vila named it the best overall robotic pool cleaner, with a 4.8 out of 5 rating and a 5 out of 5 score for value Bob Vila guide ↗. The retailer Poolbots says it works in freshwater and saltwater pools Poolbots listing ↗.
Where it falls short
It skips the waterline. Maytronics lists waterline scrubbing as no, so the greasy ring at the surface still needs a brush Maytronics ↗.
Steps are a weak spot. Bob Vila found it can get stuck on steps and need help, and some Poolbots reviewers said it often gets stuck on steps, ledges or corners Bob Vila guide ↗ Poolbots listing ↗.
There is no app, remote control or full bag indicator Maytronics ↗. Bob Vila also noted the power supply is water resistant, not waterproof, and that you need a caddy to manage the cable Bob Vila guide ↗.
It is an older design. Poolbots says it uses a Gen 1 standard fine filter without NanoFilters or MaxBin, so it catches fewer fine particles such as sand, and describes it as overshadowed by newer models Poolbots listing ↗.
