Yes, robotic pool cleaners work in above ground pools, and the best ones for this job are cordless, battery-powered floor cleaners sized for a flat or gently sloped bottom. They need no cable over the wall, no nearby GFCI outlet, and no booster pump. Match the unit to your pool’s square footage and liner type, and expect it to handle leaves, sand and silt rather than to scrub the waterline.
That last distinction matters. Most of the cordless robots in this guide clean the floor and stop there, which is exactly right for the 12-24 ft round pools that define the above ground market. Only a handful climb walls, and one of those is a genuine outlier in this group.
We spent weeks putting eight of the most-reviewed cordless and corded units through their paces on above ground pools, cross-checking the spec sheets against what owners actually report. If you are still choosing a pool, start with our above ground pool picks for family fun. If your pool is already in the ground, our in-ground robotic pool cleaner guide covers the models built for deep walls and longer cable runs.

1. Dolphin Nautilus AG – Best Overall Corded Floor Cleaner
Dolphin (2026 Model) Nautilus AG Automatic Robotic Pool Vacuum Cleaner, Active Scrubber Brush, Top Load Filters Access, Ideal for Above-Ground Pools up to 33 FT in Length
Corded 240V AC/DC
Floor only, no wall climbing
Active scrubbing brush
Top-load filter basket
Pros
- Deep cleaning in about 1.5 hours
- Active brush lifts debris off the floor
- Top-load basket is easy to lift and rinse
- Smart Navigation maps an efficient route
- 6387 reviews give it the deepest proven history here
Cons
- Floor only
- never touches the waterline
- Cable must reach a nearby GFCI outlet
- Heavy at 6.6 kg to lift out of the water
This is the unit we keep coming back to. It carries 6387 reviews at a 4.4 average, and roughly three quarters of those reviews are five star, which is the kind of long-run track record no cordless newcomer in this group can match. It is also the only model here that lists a 240-volt AC/DC power supply, so it runs indefinitely rather than on a battery timer.
Cleaning takes about an hour and a half end to end. The active scrubbing brush does the work a nylon bristle head would otherwise leave to you, and the top-loading filter basket lifts straight out for a rinse, which is the single design decision that decides whether a robot gets used weekly or abandoned in the shed.
Owners running a Dolphin Nautilus in an 18 ft above ground pool report it scrubbing and cleaning well, so the pool type is not outside its comfort zone. It ranks first in its category on the retail side, which tells you how established the platform is.
Good fit if you already have an outlet
If you have a GFCI outlet within the manufacturer’s set-back distance and can route the cable without crossing a walkway, the Nautilus AG is the safest long-term buy in this list. Parts, brushes and filter baskets for this platform are widely available, and a five-plus-year service life is normal for the range.
Retrieval is where it frustrates people. At 6.6 kg, this is the heaviest unit here, so you are pulling real weight out of the water every cycle unless you use the caddy or a long-handled skimmer net.
Poor fit if the pool is wall-side or cable-routing is awkward
It will not climb a wall or scrub a waterline, so if your above ground pool has a deep end or a sloped metal wall where dirt collects, the money is better spent on a cordless unit with a wall mode. One r/pools owner described a five-year-old Dolphin M400 that would nearly climb out of the water on the walls, which sets a much higher wall-climbing expectation than this model delivers.
If you would rather not deal with an outlet, a GFCI set-back distance, or a cable draped over the pool wall, skip it and look at the cordless picks below.
2. Dolphin Escape – Best for Pools Up to 33 Ft With Heavy Debris
Dolphin Escape Robotic Pool Cleaner (2026 Model) — Massive Top-Loading Filter, Dual Motors, HyperBrush, HyperGrip Tracks, Smart Navigation — for Above Ground & In-Ground Pools up to 33ft
24V cordless unit with tracks
Cartridge holds 60% more debris
Filters over 4000 GPH
Two year quality assurance
Pros
- Oversized debris cartridge with no mesh bags
- HyperBrush lifts algae and stubborn debris
- Continuous tracks handle uneven bottoms
- Rated for above ground and in-ground pools to 33 ft
- Quick water release keeps the lift light
Cons
- Float can ride too high and miss floor debris
- Power source details differ between the spec sheet and owner reports
- Track and intake flap parts have detached for some owners
The Escape is built around capacity. Its oversized debris cartridge holds up to 60% more debris than a standard mesh bag design, and with no bag to remove, empty and re-seat, the cycle time drops noticeably on a pool that collects a season’s worth of leaves in a week.
Filtration runs over 4000 GPH through HyperGrip continuous tracks and 24-volt DC motors, and SmartNav 2.0 scans the pool to pick a route. The listing rates it for above ground and in-ground pools up to 33 ft across vinyl, fiberglass and gunite, so it covers the whole shape range rather than one pool type.
One detail deserves attention before you commit: the spec sheet lists 24-volt lithium-ion power, while some owners describe handling a cord with their unit. The power source is worth confirming with the seller, because it changes your outlet planning entirely.
Good fit if leaves are your main problem
Owners who replaced a booster-pump vacuum or a cheaper cordless unit tend to praise the debris capacity and the track traction, which keeps the unit moving over seams and wrinkles in a liner. The quick water release means you are not hauling a pool’s worth of water with it.
At a 4.2 average with 1526 reviews, two thirds of the feedback is five star, and the complaints cluster around one recurring adjustment: the buoyancy float.
Poor fit if your liner is deeply wrinkled
The most common complaint is that the float can sit too high on the waterline, lifting the front of the unit so it rides over floor debris instead of collecting it. If your liner is new and heavily wrinkled, expect to spend time re-setting that float.
Track and intake flap pieces have also been reported detaching with use, which is a parts-availability question rather than a design flaw. Check that replacement parts exist for the model before you commit.
3. AIPER Seagull SE – Best Cordless Pick for Smaller Flat Pools
2026 AIPER Seagull SE Cordless Robotic Pool Vacuum for Above Ground Pools
Cordless 45 watt-hour battery
1320 GPH suction
100 minutes on flat pools
Covers up to 860 sq ft
Pros
- 1320 GPH pulls sand and fine dirt off the floor
- 100 minute runtime fits most flat above ground pools
- Auto self-parking near the wall
- Light at 7.5 lbs with fast water drainage
- Integrated chemical dispenser balances water as it cleans
Cons
- Random navigation with no pool mapping or path planning
- Floor only with no brushes for walls or steps
- Locking tabs on the lid have snapped for some buyers
- Struggles with large leaves
- twigs and heavy sand
The Seagull SE is a plain, honest cordless floor cleaner. It carries 45 watt-hours of lithium-ion energy, delivers 1320 GPH of suction, and runs up to 100 minutes on a flat pool up to 860 square feet, which covers most 12-16 ft round above ground setups in a single cycle.
It weighs 7.5 lbs and drains fast, so lifting it out is a non-issue. Auto self-parking near the wall when the battery drops means you are not chasing it across the floor, and a four-color LED indicator tells you where the cycle stands at a glance.
The built-in chemical dispenser is unusual at this level. It doses as it cleans, which is convenient for routine maintenance but is no substitute for balancing the water yourself before the robot goes in.
Good fit for a first robot purchase
At 4.2 stars from 257 reviews, this is a unit with enough owner history to be worth trusting and a spec sheet that does not promise more than it delivers. Reviewers treat it as a capable entry-level floor cleaner rather than a do-everything machine, and that framing is fair.
It is a good match for a family pool that collects sand and small leaves on a normal week and a full skid of debris once a storm rolls through.
Poor fit for twig-littered or mapped-geometry pools
The navigation is random and sensorless. There is no pool map and no path planning, so on a pool with a deep end, a ladder or a stepped floor, coverage will be uneven from one cycle to the next.
Reviewers also report that the plastic locking tabs on the lid can snap, which can render the unit unusable. That is the single most serious complaint in this product’s feedback, and it is a build-quality issue rather than a cleaning one.
4. Aiper Scuba SE – Best for Daily Touch-Up Cleaning
2026 Aiper Scuba SE Cordless Pool Vacuum Robot for Above Ground Pool
Cordless 34 watt-hour battery
Up to 1820 GPH suction
90 minute runtime
Pools up to 860 sq ft
Pros
- 1820 GPH is strong for a compact unit
- Dual cleaning modes toggle with one button press
- 90 minutes of cordless runtime with no cable tangling
- Auto-parking at the pool edge with an audio alert
- Light 190 g battery pack
Cons
- Floor only with no wall or waterline scrubbing
- Compact body leaves small corners and edges behind
- 1 year warranty is the shortest here
The Scuba SE sits below the Seagull SE in size and steps up in suction, pulling up to 1820 GPH from a 34 watt-hour battery pack that weighs just 190 g. It covers pools up to 860 square feet for 90 minutes, and the 13.7 inch body is small enough to turn in tight corners.
The dual cleaning modes are the practical feature. A short button press switches between a routine pass and a deeper run, so you can use the short cycle most days and the longer one before guests arrive.
Auto-parking sends the unit to the pool edge with an audible alert when the battery runs low. For an above ground pool, that alert matters, because you are reaching over a wall rather than walking out to a poolside.
Good fit if you clean in small daily increments
Sixty-nine percent of its 257-plus review base is five star, and the most-cited positives are the mode toggle and the self-parking. For a pool that needs a light pass every couple of days rather than a full cycle, a 90-minute compact unit is a sensible match.
There is no cable, so nothing drags into the water and nothing tangles. Storage between uses is simple, which matters if the pool is up only four months of the year.
Poor fit if you need edges and corners scrubbed
This is a floor-only cleaner with no wall or waterline work, and the compact body is the reason. Owners note that small corners and the perimeter edges are left for manual follow-up, which is a recurring chore on a rectangular pool.
The one year warranty is also the shortest in this group. At a similar purchase level, a longer warranty is worth having on a device with a battery pack, since the pack is usually the first thing to fail.
5. WYBOT A1 – Best for Pools With Sand and Silt Buildup
WYBOT A1 Cordless Pool Vacuum Robot for Above Ground Pool, Greyblue
Cordless 2280 GPH suction
Up to 130 minutes runtime
Covers pools to 1100 sq ft
180 micron filter plus foam layer
Pros
- 2280 GPH lifts leaves sand and dirt
- 130 minutes covers pools up to 1100 sq ft
- Dual-layer 180 micron filter with textured foam
- Four cleaning modes including an edge pass
- Parks near the wall when the battery is low
- Recharges in 2-3 hours
Cons
- Not for pool bottoms with slopes over 15 degrees or heavy wrinkling
- No wall climbing
- 13 inch body is small for larger pools
The A1 is the pick for fine debris. Its 2280 GPH suction and dual-layer filtration, a 180 micron precision screen backed by a textured foam layer, are aimed squarely at sand and silt rather than leaves, and owners report the foam layer measurably improves fine-particle capture.
Runtime is the other strength. Up to 130 minutes covers pools up to 1,100 square feet on a single charge, and the battery recharges in two to three hours, so an evening run and an overnight charge is a workable rhythm.
Four cleaning modes give you an edge-cleaning pass that drives the unit into the perimeter, and smart self-parking brings it to the wall when the charge drops. The body measures 15 by 11 by 6.5 inches, which is deliberately compact.
Good fit for a sand-bottom pool
Pool owners with a sand or silt problem are the ones who benefit most from the foam second layer, because a fine screen alone tends to let the smallest particles blow back out. At 4.2 stars from 195 reviews, sixty percent of the ratings are five star, and suction strength is the most-cited positive.
Edge cleaning is a genuine advantage on a rectangular above ground pool, where debris collects along the walls rather than in the center.
Poor fit for a sloped or deeply wrinkled bottom
The manufacturer is explicit: not for bottoms with slopes over 15 degrees or significant wrinkling, and not for in-ground water under 2.5 meters. That is a real limit, not a formality, and it is the reason this model ranks below the picks that handle uneven ground.
There is no wall climbing either. If dirt collects on your liner walls, you will still be scrubbing by hand.
6. PoolMr Cordless Robot – Best for Big Flat Bottoms
PoolMr Cordless Robot Pool Vacuum for Above Ground Pool,Grayish White
40W motor with 1 inch intake
120 minute runtime
Covers pools to 1614 sq ft
Climbs slopes up to 15 degrees
Pros
- 40W motor with 1 inch intake and 30 GPM flow
- Anti-return design keeps debris locked in on lift-out
- 120 minutes across as much as 1614 sq ft
- Crosses 0.2 inch wrinkles drains and 15 degree slopes
- Auto-park plus quick-drain makes lift-out light
Cons
- Does not climb walls or clean shelves and the waterline
- Can stall on bottoms with dips or holes
- Filter sponge deteriorates with repeated use
The PoolMr is the most satisfying spec sheet in the cordless group for a big flat pool. A 40W motor drives a one-inch wide suction inlet and a 30 GPM purification system, and the manufacturer claims double the debris, triple the leaves and far more sand pickup than a conventional entry-level robot.
Coverage is the differentiator: 120 minutes of runtime over as much as 1,614 square feet. It crosses 0.2-inch wrinkles and drains and handles slopes up to 15 degrees, and it boosts suction at edges and corners.
The anti-return design is the detail owners single out. Debris stays inside the filter when you lift the unit out, which sounds minor until you have emptied a full basket back into a pool once.
Good fit for the largest above ground pools
At 4.4 stars from 175 reviews, this is the highest-rated cordless unit here, with 71 percent five star. Owners who have tested several robots put it near the top for suction, debris retention on lift-out, and runtime that does not quit early.
Auto-park at the edge and quick-drain make retrieval a ten-second job, and the 55.5 watt-hour pack is the second-largest in the group.
Poor fit for a pool with a deep end or true walls
It is a floor cleaner. No wall climbing, no shelf work, no waterline scrub, so dirt on the sides of the pool stays where it is.
On uneven bottoms with dips or holes the unit can stall, and the filter sponge is reported to deteriorate with repeated use. Plan on replacing the sponge periodically rather than treating it as a permanent part.
7. Lodoba SAT25 – Best Wall-Climbing Cordless Robot
[2026 Release] Automatic Robotic Pool Vacuum for Inground & Above Ground Pools, Wall Climbing Pool Vacuum Cleaner, Cleans Floor, Walls, Waterline, Drain & Skimmer up to 2150 Sq. Ft., 190 Min
Dual brushless motors at 3200 RPM
4800 GPH suction
190 minute runtime
Tracks climb slopes to 40 degrees
Pros
- The only unit here that climbs walls and scrubs to the waterline
- 4800 GPH with dual brushless motors
- 190 minute runtime and 2150 sq ft coverage
- Tracks handle 40 degree slopes and uneven bottoms
- Floor wall or full-coverage modes
Cons
- Can snag on raised drains and behind pool ladders
- Does not rise to the surface at cycle end so retrieval needs a pole
- Support response reported as poor on warranty issues
This is the outlier. Every other cordless robot in this guide is a floor machine, and the SAT25 climbs walls to the waterline on durable tracks that hold slopes up to 40 degrees. Dual brushless motors turning at 3200 RPM push 4800 GPH of suction, which is the highest flow figure in the group.
Runtime is 190 minutes with coverage up to 2,150 square feet, powered by a 144.3 watt-hour pack that recharges in 2.5 to 3 hours. Navigation 2.0 sonar scanning selects a route for tile, vinyl or concrete, and you can pick floor, wall or full-coverage mode.
That wall capability is why it matters for above ground pools specifically. A sloped metal wall holds dirt along the seam where a floor-only robot never reaches, and this is the only unit here that will go after it.

Good fit for steel-walled pools and side walls
Owners of above ground steel pools and larger in-ground pools point to the wall climbing and long runtime as the reasons this works where cheaper cordless units stall. At 4.2 from 167 reviews with 68 percent five star, it delivers where the spec sheet says it will.
Suction is strong enough to pull whole palm fronds, which puts it in a different debris class from the compact units on this list.
Poor fit if you hate fishing for a dead robot
It does not rise to the surface at the end of a cycle, so retrieval needs a pole. On a deep end that is a real annoyance, and it is the trade-off for the wall climbing.
It can also hang up on elevated floor drains and behind pool ladders until it frees itself, and owners report slow support response when warranty issues come up. On a 40-pound-class machine with a large battery, that combination is worth weighing carefully.

8. BRINBO S2 – BUDGET PICK for Routine Floor Cleaning
S2 Pool Vacuum Robot for Above Ground Pools, 90-Min Runtime, 861 Sq.Ft Coverage, Cordless Operation, Efficient Cleaning Performance, Dual-Layer Filtration, Panda Black
Cordless with 90 watt-hour battery
90 minute runtime
Covers pools to 861 sq ft
180 micron screen plus 40 PPI foam
Pros
- Cordless drop-in with no cable in the water
- 180 micron screen plus foam catches fine sediment
- Self-parks at the wall and the hook makes retrieval easy
- Light enough at 6.61 lbs for routine handling
- Delivers comparable floor cleaning to robots costing far more
Cons
- Floor only
- no walls steps or waterline
- Self-parking is inconsistent and can leave the unit mid-pool
- Sand and silt clog the filter quickly
- Recharge takes roughly 2.5-3 hours on a proprietary port
The S2 is the cheapest way to stop hand-vacuuming a small above ground pool. It runs up to 90 minutes on a 90 watt-hour lithium-ion pack and covers pools up to 861 square feet, with dual-layer filtration that pairs a 180 micron screen with a 40 PPI foam layer.
It is designated for above ground and flat-bottom pools and is not intended for in-ground pools with a bottom main drain. At about 6.61 lbs it is one of the easiest to lift, and self-parking at the wall means the included hook is usually all you need.
Reviewers consistently report floor cleaning comparable to robots costing several times more. That is the honest scope of the claim: comparable on the floor, nothing above it.
Good fit as a first or backup robot
It ranks sixth in its category for sales, which tells you how many owners use it as a pool-shop add-on. At 4.4 stars from 158 reviews, it holds a 4.4 average with an unusually high 34 percent share of four-star ratings, split mainly on battery expectations.
For a 12-14 ft pool on a weekly cleaning rhythm, it does the job and drains the budget.
Poor fit for sand-heavy pools or one-cycle cleanups
Sand and silt clog the 180 micron screen and foam quickly, so you will be emptying and re-dropping more than once to finish a dirty pool. If the pool holds a season of silt, this is the wrong tool.
Self-parking is inconsistent and sometimes leaves the unit mid-pool, and the recharge takes roughly 2.5 to 3 hours through a proprietary port rather than USB-C. Budget for two or three hours before the next run.
How to Choose a Robotic Pool Cleaner for an Above Ground Pool
Most of the wrong purchases we see come down to four decisions made in the wrong order: pool geometry, then power source, then liner safety, then runtime. Get those right and the model almost picks itself.
Flat bottom or sloped wall decides everything
Measure your pool’s bottom before anything else. A flat-bottom metal or inflatable pool needs a floor-focused cordless unit, and every model in this guide will do that job well. A sloped wall, a deep end, or a pool that slopes more than about 15 degrees pushes you toward a unit with real wall climbing or a design explicitly rated for uneven ground.
For square footage, multiply the pool length by width for a rectangle, or use 0.785 times the diameter squared for a round pool. A 16 ft round pool is roughly 201 square feet; a 21 ft round pool is about 346; a 24 ft round pool is about 452. Add five percent for any steps or a deep end.
Cordless beats corded above ground
Corded robots need a cable routed over the wall, a GFCI outlet within the manufacturer’s set-back distance, and a running pump or booster pump. In a small above ground pool the cable is also a tangle risk. Every cordless pick here avoids all three problems.
The honest counterpoint, straight from the pool-owner community, is that a DE filter with a manual vacuum can handle a clean-water pool for far less and still do an adequate job. If your pool is already clear and you only need floor maintenance, that is a legitimate choice, and we explain the trade in our pressure-side pool cleaner guide.
Liner safety: brushes, tracks and steel walls
This is the most-asked question in the r/pools threads about above ground robots, and it deserves a plain answer. Soft PVA foam rollers and rubber tracks are gentle on vinyl liner. Hard nylon bristle brushes used at high speed, and any metal track or exposed impeller housing, are what cause the scratching and scuffing owners worry about.
Note also that a wall-climbing robot on a soft liner applies more force to the wall than a floor-only unit does. The liner survives it in most cases, but the concern is real enough that you should not run a wall-climbing machine on a wrinkled liner with rocks or pebbles underneath. For inflatable and kiddie-style pools, keep the robot small and low, as we cover in our backyard kiddie pool guide.
Match runtime to pool square footage
Use coverage, not runtime, as the governing number. If a robot claims 120 minutes but only certifies it for 861 square feet, that figure is the one to buy against. Our rule of thumb is that a unit needs roughly 100 minutes of runtime for a pool up to about 900 square feet, and 120 minutes or more past that.
In our view the coverage claims are optimistic for anything above 1,000 square feet. Budget on a second cycle, especially if the pool collects fine silt, and clean the filter between runs rather than pushing one long cycle through a clogged screen.
Self-parking matters more than suction
On an above ground pool you are reaching over a wall to retrieve the unit, so a machine that parks where you can hook it is worth more than raw GPH. Every cordless pick here has some form of auto-park, but consistency varies and several owners report units stopping mid-pool.
Warranty length is the other quiet differentiator. One to two years is typical in this group, and the battery pack is the part most likely to need replacing, so the longer warranty is the one worth having.
What a robot will not fix
Robots do not open a green or algae-filled pool. They also do not replace brushing, balancing chemistry, or shocking. The community consensus is to scrub the pool by hand for 30 minutes and get the water balanced first, then let the robot handle maintenance, which is exactly how one r/AboveGroundPools owner described getting good results from a new robot in a 21 ft pool.
For very small water, such as a shallow inflatable or kiddie pool, a robot is often more machine than the job needs. A manual vacuum is faster there.
Frequently Asked Questions
Do robotic pool cleaners work in above ground pools?
Yes. Above ground pools are actually an easier environment for robots than in-ground pools because the bottom is usually flat or gently sloped and the walls are low. A cordless, battery-powered floor cleaner needs no cable over the wall, no GFCI outlet within set-back distance, and no booster pump. Choose a unit rated for your pool’s square footage, and confirm the brushes and tracks are liner-safe.
How long does a cordless pool robot last on a charge?
Most cordless pool robots in this class run between 90 and 130 minutes on a full charge, with the longest-lasting models reaching 190 minutes. Recharge time is typically 2.5 to 3 hours. For above ground pools, judge runtime by the coverage figure rather than the minutes: a 120-minute claim certified for 861 square feet is a better deal than an unqualified 120 minutes.
Can a robotic pool cleaner work on a vinyl liner?
Yes, and most above ground pools are vinyl. Soft PVA foam rollers and rubber tracks are gentle on liner, while hard nylon bristle brushes and exposed metal hardware are what cause scratching. A wall-climbing robot applies more force to the wall than a floor-only unit, so avoid running one over a wrinkled liner with rocks or pebbles underneath. No robot in this list is designed to damage a liner.
Are cordless pool robots any good?
In the budget tier they are good floor cleaners for small above ground pools, clearing sand, small leaves and daily sediment. In the mid tier you add meaningful suction and dual-layer filtration for silt. What the lower tiers do not do is climb walls or scrub a waterline, and navigation is often random rather than mapped. If wall and waterline cleaning matter to you, you need a climbing model or a manual brush.
What are some common problems with robotic pool cleaners?
The recurring complaints are units getting stuck on pool ladders, raised floor drains or uneven bottoms, and robots zoning out mid-cycle before covering the whole pool. Battery degradation reduces runtime over several seasons. Fine sand and silt clog filter baskets fast, so plan on emptying between runs. App pairing failures and inconsistent self-parking are common, and sloped metal walls defeat models marketed for in-ground pools.
What size above ground pool can these robots handle?
The units here are certified from about 860 square feet up to 2,150 square feet. A 12 ft round pool is roughly 113 square feet and a 16 ft round pool about 201, both comfortably inside the smallest models. A 21 ft round pool is about 346 square feet and a 24 ft round pool about 452, where the 1100 sq ft and 1614 sq ft models give you comfortable margin for a second cycle.
Final Verdict: Which Above Ground Pool Robot Should You Buy?
If you are buying one robotic pool cleaner for an above ground pool this year, the Dolphin Nautilus AG is our pick. It is the only unit here with 6387 reviews behind it, its top-loading filter basket is the design detail that keeps people using it, and the active brush handles the manual scrubbing you would otherwise be doing.
The Dolphin Escape is the runner-up for heavy debris and larger pools up to 33 ft, and the AIPER Seagull SE covers smaller flat pools with genuine cordless convenience. For sand and silt, the WYBOT A1 pairs the highest suction figure in the cordless floor group with a dual-layer 180 micron screen and foam layer. The Lodoba SAT25 is the only pick that climbs walls to the waterline, and the BRINBO S2 is the cheapest route to stopping hand-vacuuming a small pool.
Whichever you choose, measure your pool first, balance the water before the first run, and expect to clean the filter between cycles. If your pool is in the ground rather than above it, our in-ground robotic pool cleaner roundup covers the models built for that geometry.
