What it is
Maytronics' Dolphin line is the long running name in robotic pool cleaners, and the Nautilus CC Plus is one of its best known models, with 13,982 ratings on the standard model's Amazon listing. Maytronics sells two versions on its US site:
| Version | Part number | Pool length | Notes |
|---|---|---|---|
| Nautilus CC Plus w/ Wi-Fi | 99996409-PCI | Up to 40 ft | MyDolphin Plus app, weekly timer |
| Nautilus CC Plus | 99996403-PC | Up to 50 ft | Active brush, fine plus ultra fine filter kits |
Both are corded robots for in ground pools. The cable runs from a poolside power supply through an anti tangle swivel, and the robot cleans the floor and climbs the walls. This review centers on the Wi-Fi model because app scheduling is what most buyers want in 2026.
Pricing explained
BestBots does not list prices for robots sold on Amazon, so check the current price with Maytronics, a Dolphin dealer or Amazon. Cost points to plan for:
- No battery: the biggest long term saving. Cordless robots eventually need battery replacements; a corded robot does not.
- Filters: the top access ultra fine filter kit is a reusable consumable.
- Caddy and cover: some Amazon bundles include a caddy and cover.
- Warranty: 1 year, against 3 years on Beatbot's cordless range.
Key features
Corded power and the swivel
Corded robots are the original robotic pool cleaner design. You never wait on a charge, and the robot runs as often as the timer says. The anti tangle swivel lets the cable rotate as the robot turns so it does not coil up, the classic corded robot annoyance.
2 hour cycles and the weekly timer
The default cycle is 2 hours, and a weekly timer schedules runs. The Wi-Fi model lets you set and change that schedule from anywhere in MyDolphin Plus.
Suction, brushes and coverage
Suction is rated at 4,500 GPH, below cordless rivals like the Aiper Scuba X1 (6,600 GPH) and Beatbot Sora 70 (6,800 GPH). The Wi-Fi model has 2 combined brushes and no active brush on its spec sheet; the standard CC Plus page describes an active brush that power scrubs floors and walls. Coverage is floor and walls. The Wi-Fi spec sheet lists waterline scrubbing as no, and there is no surface skimming.
Top access filter
The top load filter lifts out without flipping the robot, which is the chore owners repeat most. The Wi-Fi model ships with an ultra fine filter kit; the standard model includes fine and ultra fine kits.
Pool fit
Rectangular, round, freeform and kidney shaped in ground pools. No above ground support on the Wi-Fi page.
Physical specs
20.8 lbs, 16.8 by 16.4 by 10.4 in, which makes it lighter than the Beatbot AquaSense 2 Ultra (29.1 lbs dry).
What users say
- Amazon, standard model: 4.3 from 13,982 ratings, the deepest rating history in our pool guide.
- Amazon, Wi-Fi model: 3.5 from 3,298 ratings. The gap between the two listings suggests the Wi-Fi layer and app pairing are where some owners hit trouble.
- Maytronics store, standard model: 4.0 from 123 reviews; brand hosted, not used in our scores.
- App Store: MyDolphin Plus rates 4.7 from 8,911 ratings, which is the best app record among pool robot brands we track.
Privacy and security
There is no camera on the Nautilus CC Plus. The Wi-Fi model connects to MyDolphin Plus for scheduling and control. Maytronics publishes a product security page on its US site. Privacy exposure is low: the robot reports status and schedules, not images.
How it compares

| App | MyDolphin Plus, 4.7 (8,911) | Aiper, 4.1 (267) | Beatbot, 4.0 (307) |

Setup and maintenance
Setup means placing the power supply a safe distance from the pool edge, connecting the floating cable, and lowering the robot in. The Wi-Fi model then pairs with MyDolphin Plus, where you set the weekly timer. After that, the routine is short: empty and rinse the top access filter after each cycle, and check the cable for twists now and then, even with the swivel.
Two habits extend the life of any corded robot. Lift it by the handle, never the cable, and keep the power supply covered and out of standing water. Corded robots do not have a battery that fades with age, which is the main reason owners keep them for many seasons.
Who it is for
- Owners who want weekly cleaning without charging or retrieving a robot to plug in.
- In ground pools up to 40 ft (Wi-Fi) or 50 ft (standard).
- Buyers who value years of rating history over new features.
- Households that want app scheduling from a well rated app.
Who should skip it
- Pools where the waterline or floating debris is the main problem.
- Owners who want the longest warranty; Beatbot offers 3 years.
- Anyone who dislikes a cable and power supply at poolside.
- Above ground pool owners.
Alternatives
- Beatbot AquaSense 2 Ultra: cordless, cleans five zones including surface and waterline, 3 year warranty.
- Aiper Scuba X1: cordless, 6,600 GPH, 3 micron filter, waterline cleaning.
- Beatbot Sora 70: cordless with surface cleaning, above ground or in ground.
- Mammotion Spino E1: entry cordless option for smaller pools.
Verdict
The Nautilus CC Plus is the low maintenance classic. Corded power, a weekly timer and a top access filter make it the easiest robot to live with if floors and walls are what you need cleaned, and the standard model's 13,982 Amazon ratings are the deepest track record here. It is weaker on coverage than 2026 cordless robots, with no waterline scrubbing on the Wi-Fi model, no surface skimming and a 1 year warranty. Pick it for set and forget floor and wall cleaning; pick the Beatbot AquaSense 2 Ultra if you want the whole pool covered.

Is the Dolphin Nautilus CC Plus worth it?
If you want a pool robot you never charge and rarely think about, yes. It plugs in, runs on a weekly timer and has years of owner ratings behind it, including 4.3 from 13,982 on the standard model's Amazon listing. It does less than cordless flagships: no surface skimming, no waterline scrubbing on the Wi-Fi model, and a 1 year warranty.
What is the difference between the Nautilus CC Plus and the CC Plus Wi-Fi?
The Wi-Fi model adds MyDolphin Plus app control so you can schedule and control it from anywhere. Maytronics lists the Wi-Fi model for pools up to 40 ft and the standard CC Plus page for pools up to 50 ft, and the standard model's page describes an active brush.
Does the Dolphin Nautilus CC Plus clean the waterline?
Maytronics' spec page for the Wi-Fi model lists waterline scrubbing as no. It climbs and cleans walls. If tile line scum is your main issue, look at Aiper's waterline mode or Beatbot.
How long does a Dolphin Nautilus CC Plus cycle last?
The default cycle is 2 hours. Because it is corded, it can run every scheduled day without waiting on a charge.
Can the Nautilus CC Plus be left in the pool?
Maytronics positions it as always cleaning, never charging, and the weekly timer is built for regular unattended runs. Follow the manual on storage and keep the power supply away from the water.
What is the difference between the Nautilus CC Plus and CC Pro?
Maytronics sells the CC Pro as a separate model in its best performance range, and Amazon's CC Pro listing advertises a waterline scrubber brush and pools up to 50 ft. Check the CC Pro spec page if waterline cleaning matters.
How heavy is the Dolphin Nautilus CC Plus?
20.8 lbs for the Wi-Fi model, measuring 16.8 by 16.4 by 10.4 in.
What warranty does the Dolphin Nautilus CC Plus have?
1 year, per Maytronics' product pages. Beatbot's robots carry 3 years.
