Dolphin Nautilus CC Plus
Corded wall-climbing robot for in-ground pools to 40 ft · Reviewed by Katie · amazon.com live, Sept 24 2026
Why it scored a 83
The Nautilus CC Plus is the most-reviewed robot in this group, and it scores 83 on the back of Reliability 93 and Quality 90 across 13,961 ratings at 4.3 stars. It is corded: a floating cable runs to a power supply beside the pool, so there is no battery to fade and no waiting on a charge. It climbs walls, scrubs with an active brush and finishes a cycle in about 2 hours on in-ground pools up to 40 ft. The trade-offs are Features at 78, since this version has no app, no scheduling and no surface parking, and Warranty at 55, because Maytronics lists 1 year on current Nautilus models.

Should you buy the Dolphin Nautilus CC Plus?
The Dolphin Nautilus CC Plus is for an in-ground pool owner who wants the proven, plug-in option and has no use for an app. At $829.00 it ranks #2 of 10 in our Robot Pool Cleaners category. It costs $130 more than the cordless Beatbot Sora 30, which scores higher and adds waterline and ledge cleaning. If you want Wi-Fi scheduling on a corded Dolphin, the Dolphin Proteus DX5i adds it, but at $1,199.00.
Where it earns its score
- Deepest track record. 13,961 ratings at 4.3 stars is the largest owner base in the category, which is why Reliability sits at 93.
- Corded power. No battery to degrade or recharge; drop it in, power it on and it runs a cycle of about 2 hours.
- Wall climbing with an active brush. It climbs walls and scrubs with a spinning brush on any pool shape or surface type.
- Top-load filter. The filter basket lifts out from the top, so emptying it does not mean flipping the robot over.
What to know first
- Warranty is the lowest factor at 55. Maytronics lists 1 year on current Nautilus models, shorter than the 2 years on most cordless rivals here.
- Few smart features. No app, no scheduling and no surface parking on this version; you start it by hand and lift it out by its handle.
- Cable management. A corded robot needs its power supply near the pool, and the floating cable should be uncoiled between runs to avoid tangles.
Our verdict
The Dolphin Nautilus CC Plus scores 83, a Good Buy and #2 in our Robot Pool Cleaners category, carried by Reliability (93) and Quality (90). Buy it for an in-ground pool up to 40 ft if you want the corded robot with the longest track record here. If you want cordless convenience and waterline cleaning for less, the Beatbot Sora 30 (85) is $699.00.
