All robot pool cleaners. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Aiper Scuba X1 | Polaris EPIC 8642 iQ |
|---|---|---|
| Pool type | ||
| In-ground | GoodDesigned for in-ground pools with dock placement near pump or pool edge. | GoodEPIC line engineered for in-ground gunite pools; wall-mount plumbing and cable specs designed for this. |
| Above-ground | PoorNot designed for above-ground pools; dock stability and electrical safety not verified. | PoorCable and wall-climb geometry not compatible with above-ground frame designs. |
| Mixed setup | GoodIn-ground pools only; ensure dock can be positioned safely near circulation system. | GoodFits the location profile you selected. |
| Pool size | ||
| Small (< 400 sqft) | GoodFeature set (WavePath + MicroMesh) is overkill for pools under 8,000 gallons; a smaller budget cordless cleaner would be lower cost. | GoodEPIC 8642 targets 12K–25K gallons; smaller pools may have excessive cable and runtime overkill. |
| Medium (400 – 800) | Good12,000–25,000 gallons is the designed envelope; one 90-minute cycle achieves floor + wall coverage. | Good12,000–18,000 gallons is EPIC line design center; full coverage and app efficiency confirmed. |
| Large (> 800)they differ | Depends30,000+ gallon pools approach the battery limit; coverage times creep to 100+ minutes. Two cycles or manual supplementation recommended. | Good18,000–25,000 gallons is upper design envelope; cable length adequate for typical large-pool plumbing. |
| Debris load | ||
| Fine (sand / silt) | GoodMicroMesh filter excels at fine sediment capture; pollen and sand removed more thoroughly than standard baskets. | GoodCanister filtration handles fine sediment; post-run rinse prevents clogging. |
| Leaves / large debristhey differ | DependsHeavy leaf load risks clogging the MicroMesh; pre-skim during fall. Large leaves can block intake port. | GoodWall-climbing and aggressive brush targeted at leaf and algae load; large debris should be pre-skimmed. |
| Algae / heavy foulingthey differ | DependsFloor and wall algae handled well; waterline coverage is partial (40–60% per cycle). Heavy biofilm requires manual supplementation. | GoodBrush cartridge and waterline scrubbing address algae, manufacturer touts this as EPIC strength vs. floor-only. |
| Coverage you want | ||
| Floor only | GoodComplete floor coverage; floor-only mode available to conserve battery. | GoodWall-climbing is this model's signature; floor-only operation uses only part of its capability. |
| Floor + walls | GoodWall climbing and floor coverage integrated; wall-return engagement automatic. | GoodDual-mode (floor + walls + waterline) is the EPIC design target; full feature use. |
| Floor + walls + waterlinethey differ | DependsWaterline jet present but covers 40–60% of tile line per cycle; light algae handled; heavy biofilm requires second pass or manual brushing. | GoodThree-zone coverage (floor, walls, waterline scrub) documented in EPIC specs; this is the intended use case. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

Not compared, because fewer than two of these robots carry a published figure: Runtime, Charge time, Noise, Weight, Height.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Aiper Scuba X1
A 3 micron cartridge holds what a standard basket passes straight through, but all of it comes out by hand: the cleaner is lifted from the water and the 5 L basket rinsed at the pool edge.
WavePath 3.0 avoids the cost and the failure modes of a camera system, but it also avoids the map: there is no stored floor plan to review, name or edit between cycles.
At roughly $899 the Scuba X1 sits about $800 under the Maytronics Liberty 600’s $1,729 MSRP, but it arrives with a shorter public record: Aiper publishes no service-part pricing and no battery replacement terms, so long-run ownership cost is undocumented.
Polaris EPIC 8642 iQ
The iAquaLink app is real convenience, but corded operation is tethered convenience, cable management creates logistics that offset the app’s hands-off promise.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Aiper Scuba X1
- Owners who want the machine to empty itself
- The 5 L basket is top-loaded and emptied by hand at the pool edge, which means lifting the cleaner out of the water after a cycle. Nothing about that step is automated.
- Pools with heavy leaf debris or large obstacles
- WavePath 3.0 avoids objects but slower pathfinding than camera-vision systems; heavy debris loads may trigger premature obstacle avoidance and incomplete coverage. Pre-skimming required during fall.
- Owners wanting app-free operation
- Scheduling and cleaning history are app-only. Running the cleaner without the app means pressing the start button for every cycle.
Polaris EPIC 8642 iQ
- Above-ground pools and small in-ground pools.
- Polaris rates the EPIC 8642 iQ for in-ground pools up to 50 feet, and the 60 foot cable, control box and transport caddy are sized for that installation. On a compact pool the handling routine is the same as on a large one, and that routine is most of the ownership effort.
- Owners preferring cordless or minimal cable management.
- The 60 foot cable is not optional on this model. It runs from the cleaner to a poolside control box, the swivel reduces tangling rather than removing the cord from the routine, and the cleaner and caddy need storage between uses. As with any mains-fed cleaner, it comes out of the pool before anyone swims.
- Environments with heavy brush or concrete surface damage.
- Brush wear on rough surfaces accelerates; brush replacement intervals will increase and consumable costs rise.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Aiper Scuba X1
- After every use: Lift the cleaner out, empty the 5 L top-load basket and rinse the MicroMesh cartridge with a hose; let the machine air-dry before charging.
- While charging: Use the supplied charger, set the machine on a hard non-combustible surface away from the pool, and do not leave a charge running unattended overnight. Both CPSC recalls on Aiper’s cordless line have been charging faults, neither covering the Scuba X1: the Elite Pro GS100 in August 2023 (recall 23-784, about 22,000 units, 17 reports of the battery overheating when the cord was connected without the adapter or directly to the charging port) and the Seagull Pro in March 2025 (recall 25-187, about 32,660 units, 19 reports of units melting, smoking or catching fire on charge, traced to the high-current adapter). The 2023 recall was remedied with a free Seagull Pro, the model recalled in 2025.
- Monthly: Deep-clean the MicroMesh cartridge; check the charging contacts for corrosion.
- Every 3-6 months: Inspect the brushes and tracks for wear and lodged debris.
- Seasonally: Charge the pack before storage and top it up over the off-season; store the cleaner dry and above freezing.
Polaris EPIC 8642 iQ
- After each run: Lift out the 4 L filter canister and rinse the debris (~10 min); check the cable swivel.
- Every 2-4 weeks: Deep-clean the canister if debris load is heavy; wipe the brush cartridge.
- Every 6-12 months: Replace brush cartridge (~$60-80 typical Polaris pricing).
- Annually: Replace filter canister (~$120).
- Seasonally: Store the cleaner, caddy and control box indoors and out of freezing conditions; inspect the cable and its connector for corrosion; check wall-climb wheels for algae film.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
