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 | Polaris 9650iQ Sport | Dolphin Oasis Z5i |
|---|---|---|
| Pool type | ||
| In-ground | GoodDesigned and documented exclusively for in-ground pools; plaster and gunite verified by manufacturer. | GoodDesigned for in-ground pools; dual tracks and cable length optimized for gunite and concrete walls. |
| Above-ground | PoorManufacturer documentation restricts use to in-ground pools; above-ground vinyl liner walls risk brush abrasion. | PoorVinyl pool liners risk damage from track pressure; above-ground pools 5,000-12,000 gal are undersized for Z5i. |
| Mixed setupthey differ | DependsIf your pool mix includes any above-ground vinyl liner pools, the 9650iQ Sport is not rated for those installations. | GoodStandard for this category, confirm pool type in specs before purchase. |
| Pool size | ||
| Small (< 400 sqft) | GoodCapable in small pools but 60-foot cable generates excess slack; turning radius creates coverage gaps in tight footprints. | GoodZ5i targets 20,000+ gal pools; smaller pools may finish too quickly, overusing consumables. |
| Medium (400 – 800) | GoodSized and runtime-calibrated for mid-range in-ground pools; systematic path covers 15,000-25,000 gallons in a standard 2.5-hour cycle. | GoodOptimal for 20,000-25,000 gal in-ground pools; cable length and track endurance well-matched. |
| Large (> 800)they differ | GoodFour-wheel drive and extended runtime handle large in-ground pools; very large pools over 40,000 gallons may require a second cleaning cycle. | Depends30,000+ gal pools require cable extension (additional $120-150); single Z5i may need multiple weekly runs. |
| Debris load | ||
| Fine (sand / silt) | Good70-micron fine filter canister captures algae and fine particulates that standard bag filters pass through. | GoodPleated filter captures silt and algae; replace every 3-6 months depending on pool chemistry. |
| Leaves / large debris | GoodFilter canister capacity handles moderate leaf load; heavy leaf pools may require mid-cycle filter rinse to maintain suction. | GoodLarge leaves can clog filter quickly; pre-clean pool surface or reduce run frequency during fall debris season. |
| Algae / heavy fouling | GoodScrubbing brush contact on plaster and gunite surfaces addresses algae buildup; 70-micron filtration captures loosened algae particles. | GoodBristles agitate walls for bloom cleanup; pleated filter handles algae spores. Chemical treatment still required for heavy blooms. |
| Coverage you want | ||
| Floor only | GoodThe 9650iQ Sport covers floor, walls, and waterline by design; floor-only need means paying for wall-climb capability you are not using. | GoodZ5i excels at floor coverage but emphasizes wall-climbing; floor-only operators may prefer cheaper floor-focused models. |
| Floor + walls | GoodFour-wheel drive climbs pool walls reliably on plaster and gunite; owner reports confirm wall coverage on pools with standard 90-degree wall angles. | GoodDual tracks deliver full waterline-to-floor coverage. Primary use case for Z5i premium positioning. |
| Floor + walls + waterlinethey differ | GoodWaterline scrubbing is a documented manufacturer specification; the 9650iQ Sport is one of the few models in its class to reach the tile band. | DependsReaches waterline but does not brush tile above waterline; manual cleanup or separate tile cleaner needed. |
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.
How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.

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.
Polaris 9650iQ Sport
The cable sets the working envelope: 70 feet of tangle-reducing swivel cable on a machine rated for in-ground pools up to 60 feet. It still has to be retrieved after every cycle and occasionally untangled on pools where current or robot spin stacks loops.
Systematic gyroscopic navigation eliminates the redundant passes that random-path cleaners produce, but the robot cannot re-detect a missed zone if debris is added mid-cycle.
Maytronics Dolphin Oasis Z5i
Dual tracks climb walls and deliver full waterline reach, but the system costs $1,500+ when a floor-only corded model runs $300-500.
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.
Polaris 9650iQ Sport
- Above-ground pools with vinyl liner floors
- The 4WD drive system and aggressive brush contact are calibrated for plaster and gunite. Vinyl liner pools risk brush abrasion; manufacturer documentation restricts use to in-ground installations.
- Compact pools well inside the 60 foot rating
- The 70 foot cable and the robot's turning radius are sized for mid-to-large in-ground footprints. A short pool leaves more cable in the water than the run needs, and owner reports describe slack and incomplete coverage where corners are tight.
- Owners needing a pool cleaner under $600
- Entry-level suction-side and pressure-side options cover basic floor cleaning at far lower cost. The 4WD navigation and app features add capability that compact budgets do not require.
- Fiberglass pools where wall climb is the primary need
- Fiberglass surfaces are smooth and require less scrubbing pressure. Owner reports from fiberglass pools note the 4WD drive and brush pressure are more than the surface demands; lighter units serve this use case adequately.
- Pools with sharp main-drain obstacles or unusual bottom geometry
- Unconventional pool floor geometry with raised drains or protruding fittings can snag the cable and interrupt cleaning cycles, per owner forum accounts.
Maytronics Dolphin Oasis Z5i
- Pools longer than 50 ft or beyond the cord's reach
- Maytronics rates the Z5i by pool shape and length, up to 50 ft, and the 60 ft cable has to reach an outlet serving the pool area. Surface material is not a constraint: Maytronics sells Dolphin cleaners across pool surfaces, vinyl included.
- Renters or short-term pool owners
- Purchase price and dealer setup make ownership economical only for 5+ year tenures. No major resale market for commercial-grade dealer units.
- Owners who want cordless operation
- The 60 ft cord ties the unit to a poolside outlet, and it is placed in the water and lifted back out by hand at each cycle. There is no cordless version of this model.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Polaris 9650iQ Sport
- After every use: Remove robot from pool, rinse filter canister with garden hose to clear debris load.
- Weekly: Inspect tangle-free swivel cable for kinks or loop buildup; lay flat to re-set.
- Monthly: Check drive tracks and brushes for debris embedded in bristles; remove with stiff brush.
- Every 3-6 months: Inspect cable swivel bearing for smooth rotation; replace swivel assembly if drag is felt (roughly $25-40 from authorized dealers).
- Annually: Replace drive track brush assembly if wall-climb performance drops; manufacturer pricing approximately $35-55 per set.
- Seasonally: Winterize by draining robot completely, storing filter canister dry, and coiling cable loosely in a shaded location above freezing.
- As needed: Update iAquaLink firmware via app when prompted; connectivity issues are typically resolved by router re-pairing rather than hardware replacement.
Maytronics Dolphin Oasis Z5i
- After every cycle: Lift the filter out of the top-load housing, unsnap the bottom and rinse it with fresh water.
- Monthly: Check the brushes and tracks for wrapped debris; inspect the cable for kinks.
- Annually: Check the brushes and filter panels for wear and replace them when worn. Maytronics publishes no replacement interval or price for either.
- Seasonally: For freezing climates, remove the unit from the pool and store it and the cable indoors, out of direct sun.
- As needed: Swap between the fine and ultra-fine filter kits to match the debris the pool is carrying.
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.
