A robotic pool cleaner drives along your pool floor, and on most models up the walls too, filtering out debris as it goes. That’s one less job before a swim. We’ve lined up seven current US models on the specs their makers publish, so you can match one to your pool type, size and how hands-off you’d like to be.

| Model | Pool type | Cleans | Runtime (published) | Power | Filter |
|---|---|---|---|---|---|
| Aiper Scuba X1 Pro Max | Inground | Floor, walls, waterline, surface | Up to 12 h skimming, 5 h Eco, 3 h Max | Cordless | 3-micron + 180-micron |
| Beatbot AquaSense 2 Ultra | Large and complex pools | Floor, walls, waterline, surface | Not stated on listing | Cordless | Not stated on listing |

| WYBOT C1 | Inground, up to 1,618 sq ft | Floor, walls, waterline, steps | Up to 160 min | Cordless | Not stated on listing |
| WYBOT A1 | Unclear on listing (see below) | Not stated on listing | Up to 130 min | Cordless | 180-micron + foam |
| Dolphin Nautilus CC Plus Wi-Fi | Inground, up to 40 ft | Floor and walls | About 2 h cycle | Corded | Top-load basket |
| Aiper Scuba SE (2026) | Above ground, flat inground, up to 860 sq ft | Floor | Up to 90 min | Cordless | Not stated on listing |
Runtime is each maker’s own figure for the mode it names. A cordless robot stops when its battery runs out, so match runtime to the size of your pool. A corded robot runs on mains power and never needs charging.
The seven cleaners
Aiper Scuba X1 Pro Max
The X1 Pro Max cleans the pool floor, walls and waterline, then skims the surface for floating leaves. The listing gives 8,500 GPH of suction from dual jets and 9 motors, a 3-micron fine filter plus a 180-micron standard filter, and up to 12 hours in skimming mode. It charges wirelessly on its dock and parks at the pool edge when it’s done.
Suits: inground pools that collect leaves and floating debris.
Worth knowing: the 12-hour figure is for skimming. The listing gives up to 5 hours in Eco mode and 3 hours in Max.
Beatbot AquaSense 2 Ultra
The AquaSense 2 Ultra maps the pool with AI vision and, per its listing, recognizes debris such as leaves, berries and nuts. It cleans the floor, walls, waterline and surface, supports water clarity, comes back up to the surface when it’s done or running low, and its SmartDrain makes it lighter to lift out.
Suits: large or oddly shaped pools where smarter navigation helps.
Worth knowing: the listing doesn’t state runtime or filter rating, so check those before you buy.
Aiper Scuba S1 (2026)
The 2026 Scuba S1 runs up to 270 minutes in Eco mode and 180 minutes in other modes. Eleven sensors guide a WavePath cleaning pattern across the floor, walls, waterline and shallow areas deeper than 12 in, through 3-micron and 180-micron filters.
Suits: bigger pools where a long clean matters more than surface skimming.
Worth knowing: the listing doesn’t mention surface skimming or say which pool types it suits, so check with the seller.
WYBOT C1
The C1 is built for inground pools up to 1,618 sq ft and 9.86 ft deep. It cleans the floor, walls, waterline and steps using three motors and a gyroscope, runs up to 160 minutes after a 4-hour charge, and gets over-the-air updates through its app.
Suits: inground pools with steps you want cleaned too.
Worth knowing: the listing doesn’t state a filter rating.
WYBOT A1
The A1 lists 2,280 GPH suction, a 180-micron filter with a foam layer, up to 130 minutes of runtime and coverage up to 1,100 sq ft. It parks near the wall when the battery runs low.
Suits: smaller pools up to 1,100 sq ft.
Worth knowing: the listing title says above-ground pools, but a note on the same listing describes in-ground pools under 2.5m deep. Ask the seller which pool types it suits before you buy.
Dolphin Nautilus CC Plus Wi-Fi
The Nautilus CC Plus is corded, so it runs on mains power and you never wait for a charge. It cleans floors and climbs walls with a scrubbing brush, runs about a 2-hour cycle, takes a top-load filter basket and adds Wi-Fi scheduling. It’s rated for inground pools up to 40 ft long.
Suits: owners who’d rather plug in than charge a battery.
Worth knowing: the listing describes floor and wall cleaning and doesn’t mention the waterline. Check who the seller is and the warranty terms on the listing before you buy.
Aiper Scuba SE (2026)
The Scuba SE is a floor cleaner for above-ground and flat-floored inground pools up to 860 sq ft. It runs up to 90 minutes, starts with one button and parks itself at the edge when its battery runs low.
Suits: above-ground pools and small, flat inground pools.
Worth knowing: the listing describes floor cleaning only, with no mention of walls or the waterline. Skip it if your pool has a sloped floor.
How to choose
- Pool type. Above-ground and flat pools need less; sloped inground pools with steps need wall and step climbing.
- Size. Check the published coverage or runtime against your pool’s area.
- Debris. If leaves float in your pool, a model that skims the surface saves you a manual job.
- Cord or cordless. Cordless robots are easier to drop in; corded robots never run flat.
- Fine dirt. A 3-micron filter catches finer particles than a standard 180-micron filter.
Questions
Which of these clean the water surface?
The Aiper Scuba X1 Pro Max and the Beatbot AquaSense 2 Ultra, according to their listings.
Which works in an above-ground pool?
The Aiper Scuba SE (2026) lists above-ground pools. The WYBOT A1 title also says above-ground, but its listing is inconsistent, so check with the seller.
Which runs longest on one charge?
The Aiper Scuba X1 Pro Max lists up to 12 hours when skimming and 5 hours in Eco mode. The Aiper Scuba S1 (2026) lists up to 270 minutes in Eco. Makers measure runtime in their own modes, so compare like with like.
Do I still need to clean by hand?
A robot handles routine cleaning. You’ll still need to empty its filter and the pool’s skimmer baskets, and brush any spots it can’t reach.
