Aiper Scuba S1 vs. Dolphin Nautilus CC Plus

Who this is for

Read on if you are choosing between the Aiper Scuba S1 and the Dolphin Nautilus CC Plus and want the two makers' pool, wall and runtime figures side by side, then the tester and owner record for each. The three-way page adds Wybot.

Against the same house

Every verdict on this page comes down to three things the makers state: what kind of pool the cleaner is built for, the longest pool it is rated for, and whether it climbs walls. This pool is inground and 35 feet long with the walls in scope, so the length rating does the work: Maytronics rates the Dolphin Nautilus CC Plus to 40 ft and Aiper rates the Scuba S1 to 50 ft. The plain Dolphin Nautilus CC is rated to 33 ft and falls out on length alone.

Side by side, from the makers’ own documents

“Not captured” means the maker’s page we captured does not state it: a gap in our record, not a zero, and never filled from a sibling model. “No verified listing” means no Amazon listing for the bare unit passed our identity check yet. A price marked “list” is the maker’s list price, shown where no listing passed; a bare price is what the verified Amazon listing showed when we checked.

Buying it right

A search for any of these models returns bundles, last year’s model under a similar name and, often, the same unit under two listings at different prices. We link only a listing whose own title and model number match the bare unit. Check the seller is the maker or Amazon itself, and that the model number on the box matches the one on this page.

What this page can’t promise

Nothing here was tested by us: every measured figure belongs to the named tester, and the complaints are owners' reports. Where a maker's page contradicts itself we say so rather than pick the better reading.

The pick goes to the Dolphin on its record, not its spec sheet, and the spec sheet favours the Aiper on length, runtime and the waterline. If you weigh the makers' figures more than the testers' findings, the Aiper is the rational choice and this page says so.

A cordless runtime figure is the maker's number in the maker's pool; a dirty pool or a cold one gets less, and a corded unit's timer only helps if the power supply is somewhere it can stay plugged in.

Other houses we judged

• Half acre, no wireThe best robot lawn mower with no perimeter wire, for a half-acre yard

  A half-acre lawn, one continuous piece, a slope you notice when you push a mower up it, and no wire you are willing to bury. Every robot mower we track, judged against that yard from the limits its own maker publishes.

• Small yardThe best robot lawn mower for a small yard

  A small suburban lawn, a gentle grade, and a couple of beds to steer around. Almost every robot mower we track clears a yard this size, so the question stops being which one is big enough and starts being which one is worth what it costs.

• Inground poolThe best robotic pool cleaner for an inground pool

  An inground pool of ordinary size, with walls that need scrubbing as much as the floor does. Every robotic cleaner we track, judged against it on the pool length and wall climbing the makers publish, and then on what independent testers found when they ran the machines.

• Above-ground poolThe best robotic pool cleaner for an above-ground pool

  An above-ground pool 24 feet across, on a soft liner, with a wall you can reach over. The maker's own pool-type rating decides this page before anything else gets a say: it rules out 5 of the 13 cleaners judged here on its own.

• ComparedDolphin Nautilus CC Plus vs. Aiper Scuba S1 vs. Wybot

  Dolphin Nautilus CC Plus, Nautilus CC, Aiper Scuba S1 and two Wybots on the makers' own figures, then judged against one inground pool with walls.

• Three catsThe best automatic litter box for multiple cats

  3 cats, one of them big and one of them small, and one box that has to serve all of them. Two published limits decide it: the number of cats the maker rates the box for, and the weight range its sensors were built around.

• Pet hair, hard floorsThe best robot vacuum for pet hair on hard floors

  A shedding dog or two cats, hard floors through most of the house, low thresholds between the rooms, and a wish that the bin emptied itself. Two robot vacuums come out of that house as picks, judged from the limits their makers publish rather than from a lab's dust-pickup score.

• ComparedWybot vs. Aiper

  Aiper Scuba S1 against the Wybot C1 and S2 on pool type, wall climbing, runtime and filter figures the makers publish, judged for a 35-foot pool.

• GuideMeasure before you buy

  Every home robot is sold against a limit, and every maker calls that limit something different on its spec page. Here is how to get your own numbers first.

• GuideApps, subscriptions and what stops working offline

  Every one of these machines still moves without the internet. What you lose is the map, the schedule, the history and, on some of them, the reason you paid extra.

• GuideRecalls and battery safety for home robots

  Five recalls cover every robotic pool cleaner, mower, vacuum and litter box sold in the United States since 2020, and every one of them was about heat.
