Wybot vs. Aiper
Two cordless brands that sell mostly on Amazon, judged for one pool: 35 feet, inground, walls climbed. One of them publishes a pool length; the other publishes an area and leaves the length blank, and that gap decides the page.
For this pool, the Aiper Scuba S1. Aiper publishes the figures the house turns on: in-ground pools to 50 ft, wall climbing, waterline scrubbing, 180 min of runtime, at $500 list ($450 on Amazon when checked). Wybot publishes a rated area for the Wybot C1 of 1,615 sq ft but no pool length, so this page cannot say it clears a 35-foot pool, only that Wybot has not said either way.
The Wybot C1 is the cheaper unit at $400 on Amazon against a $570 list, rated for in-ground or above ground pool types with 150 min of runtime and a fine (180 micron) filter. The Wybot S2 at $1,000 runs 210 min and is rated for 3,230 sq ft, and Wybot does not say which pool types it is for. If price is the reason you are looking at Wybot, the C1 is the one to weigh against the Aiper; the table has every published figure.

Who this is for
Read on if you have an Aiper Scuba S1 and a Wybot in two browser tabs and want what each maker actually publishes, side by side, with the blanks marked. The three-way page puts both against the Dolphin Nautilus CC Plus.
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. Aiper rates the Scuba S1 to 50 ft; Wybot rates both of its units by area and not by length, so they come back unknown, which is not a mark against them.

Publishes the pool length this house turns on, and clears it
$450 at Amazon, September 20, 2026in-ground pool type50 ft pool length, up toclimbs wallsscrubs the waterline
Aiper rates the Scuba S1 for in-ground pools to 50 ft and 1,600 sq ft, says it climbs walls and scrubs the waterline, and gives it 180 min of cordless runtime on a 240 min charge with a ultra fine (180 micron basket + 3 micron MicroMesh) filter. It lists at $500 and was $450 on Amazon when checked. This pool is 35 feet, inside the rating, which is the one figure Wybot leaves blank.
Price as of September 20, 2026; the listing we verified as the bare unit. Sold by AiperDirect, the maker's own storefront, when we checked.
Living with it
Running costs are low by design: Aiper states there is no app subscription and no hidden fees, and the filters rinse rather than get replaced. What it asks instead is handling: Aiper tells owners to lift it out after every use and rinse the filters. The Pool Nerd found retrieving it with the included hook awkward once it is full of water, and that fine silt and sand slip through.

What independent testers found
We do not test units ourselves. These are figures and verdicts published by named testers, with the maker’s claim beside them where the tester gave it; where a tester relays owners’ reports rather than a measurement, the row says so.
| What | Finding | Tester |
|---|---|---|
| Runtime | 60-70 minutes of actual cleaning time, as owners report (maker: up to 150 minutes on a single charge) (owners' reports relayed by the tester, not a measurement) | The Pool Nerd |
| Wall climbing | Wall climbing worked but inconsistently, sliding back down before completing a full pass | The Pool Nerd |
| Noted | Captured small to medium debris but fine silt and sand slipped through the mesh filter | The Pool Nerd |
| Runtime | Battery consistently ran out around the 40-45 minute mark during testing, sometimes barely past 30 minutes (maker: about 60 minutes) | PoolBots |
| Charge time | Required at least 3 to 4 hours to fully recharge | PoolBots |
| Wall climbing | Could not handle even slight pool-floor inclines; lost traction and slid back to the bottom without assistance | PoolBots |
| Noted | Moved in a random pattern, bouncing off walls and occasionally changing direction | PoolBots |
- The Pool Nerd's final verdict on the Scuba S1 was a Disapproved rating, concluding it does not live up to expectations. (Pool Nerd Disapproved) The Pool Nerd
- The Pool Nerd names the Scuba S1 its Budget Pick among Aiper cleaners, as the cheapest wall-climbing model in the lineup. (Budget Pick) The Pool Nerd
- PoolBots does not recommend the Scuba S1 for serious pool owners, concluding it falls short on battery life, cleaning power, navigation, and build quality despite appealing to very small, flat pools on a budget. (Not Recommended for Serious Pool Owners) PoolBots

Not judged hereWybot C1
The cheaper cordless unit, rated by area with the pool length left blank
$400 at Amazon, September 20, 2026in-ground or above ground pool typeclimbs wallsscrubs the waterline
Wybot rates the C1 for 1,615 sq ft of pool and for in-ground or above ground pool types, says it climbs walls and scrubs the waterline, and gives it 150 min of runtime on a 180 min charge with a fine (180 micron) filter and a 2 years warranty. What Wybot does not publish is a pool length, which is the figure this house turns on, so the verdict reads unknown rather than fits: a blank, not a failure. At $400 on Amazon against a $570 list it is the lowest price on the page.
Price as of September 20, 2026; the listing we verified as the bare unit. Sold by Wybotic Offical US, the maker's own storefront, when we checked.
What you give up
A published pool length, and with it any way to say from Wybot's own figures that a 35-foot pool is inside its rating. And a tester record: no tester we track has published a hands-on test of it, so the tester column is empty, not negative.

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
No tester we track has published a hands-on test of the Wybot C1 or S2, so their tester column is empty, not negative, and Wybot's own pages are the only evidence we have for them. The Aiper has a tester record, and it is not all flattering; it is printed under the pick.
Nothing here was tested by us. Every measured figure belongs to the named tester, every complaint is an owner's, and both units were selling under their list prices when checked.
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 rated area says nothing about the length of the wall the cleaner has to climb.
Questions people ask
Is Wybot or Aiper better for an inground pool?
On published figures, the Aiper Scuba S1: Aiper states inground pools to 50 ft and wall climbing. Wybot states wall climbing and a rated area for the C1 but no pool length, so it cannot be judged against a 35-foot pool.
Which runs longer on a charge?
The Wybot S2 at 210 min, then the Aiper Scuba S1 at 180 min, then the Wybot C1 at 150 min. All three are the makers' figures.
Is the Wybot C1 cheaper than the Aiper Scuba S1?
When checked, yes: $400 against $450 on Amazon, both under their list prices of $570 and $500. Prices move; the buy lines under each pick show the date they were checked.
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.
- ComparedAiper Scuba S1 vs. Dolphin Nautilus CC Plus
Aiper Scuba S1 against the Dolphin Nautilus CC Plus on pool length, wall climbing, runtime and filter figures, judged for a 35-foot inground pool.
