Wybot vs Aiper: which pool robot should you buy?
Buy the Aiper Scuba S1 for an inground pool up to 50 ft long. It climbs walls, scrubs the waterline and runs 180 min on a charge. The Wybot C1 costs less, at $400, but Wybot only gives a pool area, not a length, so you can't check it against a 35-foot pool.
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 ($500 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.
This page picks only from Aiper and Wybot, by the same rule as our other pool pages. With every brand in, that rule picks the Dolphin Nautilus CC Plus.

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.

Our pickAiper Scuba S1
Publishes the pool length this house turns on, and clears it
$500 at Amazon, November 5, 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 $500 on Amazon when checked. This pool is 35 feet, inside the rating, which is the one figure Wybot leaves blank.
What testers said. The Pool Nerd: Disapproved; PoolBots: does not recommend it for serious pool owners. The Pool Nerd reviewed an earlier Scuba S1: it quotes Aiper's then-advertised 150 minutes. PoolBots does not name an edition; its unit ran 40 to 45 minutes and moved in a random pattern. We link the current edition, which Aiper rates for up to 180 minutes; no tester we can cite has reviewed it yet.
Price as of November 5, 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
The Pool Nerd reviewed an earlier Scuba S1: it quotes Aiper's then-advertised 150 minutes. PoolBots does not name an edition; its unit ran 40 to 45 minutes and moved in a random pattern. We link the current edition, which Aiper rates for up to 180 minutes; no tester we can cite has reviewed it yet.
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 (the maker's figure the tester quoted: 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 (the maker's figure the tester quoted: 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, November 5, 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 November 5, 2026; the listing we verified as the bare unit. Sold by WYBOT U.S., 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.
Owner reports, tester figures, more photos and the listings we skipped are on the Wybot C1 page. Figures from wybotpool.com. Recall screen: no US or Canada recall names this model, checked November 3, 2026.

“Not published” means the maker does not state it. Prices are Amazon’s when we checked; “list” is the maker’s price. How to read these tables.

Buying it right
Each model page lists the similar Amazon listings we did not link and why: Aiper Scuba S1, Wybot C1. How we match listings.
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 $500 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.
