Head to head
Beatbot AquaSense 2 or Dolphin Nautilus CC Plus?
Premium cordless with surface parking, or the corded Dolphin people have owned for years. The right one depends on the cable and the waterline.
Short answer: Pick the Dolphin when you want a corded robot with a huge owner record and you will live with the cable. Pick the Beatbot when retrieval and a double-pass waterline are worth the weight and the mixed reviews.

Two different promises
The AquaSense 2 is a cordless flagship. It claims a very large pool, a long floor cycle, a waterline scrubbed twice per pass, and a float-up park so you are not swimming after it. The Nautilus CC Plus is a corded scrubber with CleverClean, a weekly timer, and a swivel cable. It has been in pools long enough that the failure modes are not a mystery.
Neither is a bad default. They fail in different ways. Beatbot owners argue about suction, climb, and whether the battery matches the brochure. Dolphin owners argue about cables, cartridges, and a waterline this model does not claim to scrub.
When the Dolphin wins
Choose the Nautilus CC Plus if the pool is a normal inground bowl, you have a GFCI outlet close enough, and you would rather replace a cartridge than a battery. The weekly timer is dull in the best way. The review base is the largest in this site's lineup. You are not beta-testing the idea of a robot.
You lose the waterline. Dolphin's own chart has long left that box unchecked on the CC Plus. If the tile line is the reason you are shopping, this win flips.
When the Beatbot wins
Choose the AquaSense 2 if the pool is large, the cable is what you hate, and you want the robot waiting at the surface. The three-year replacement promise is the best warranty language in this group. Budget the lift: 27 pounds dry, more when it is late to drain. Read the recent low-star reviews for your pool surface before you buy, because the 3.9 average hides a split.
The lean on this page is the Dolphin Nautilus CC Plus. Read that review before you buy, and read the other one if your pool is the exception.
Questions
Which one is easier to retrieve?
The Beatbot. It is built to park on the water and drain. The Dolphin comes out by easing the cable to the wall, letting it drain on the edge, and lifting the handle. Never lift a Dolphin by the cable.
Which one scrubs the waterline?
The AquaSense 2 lists a double-pass waterline scrub. The Nautilus CC Plus climbs walls and is not the Dolphin model that claims the waterline.
