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 | Dolphin M600 | Polaris VRX iQ+ |
|---|---|---|
| Pool type | ||
| In-ground | GoodDesigned for in-ground gunite and vinyl liner pools; dock positioning expects fixed installation. | GoodDesigned for in-ground pools. Cable deployment and poolside power access assumed. Corded architecture suits permanent installations. |
| Above-groundthey differ | PoorCable routing and dock anchoring assume in-ground structural features; above-ground pool walls lack the needed mounting points. | DependsFunctional but cable management becomes more complex. Requires electrical access within 60-foot reach of above-ground structure. |
| Mixed setup | GoodFlexible for any in-ground pool type; confirm dock placement before purchase. | GoodStandard for this category; confirm poolside power access before purchase. |
| Pool size | ||
| Small (< 400 sqft) | GoodM600 is rated for 12,000+ gallon pools; smaller pools (under 10,000 gallons) result in cycle overlap and inefficiency. | GoodRuntime advantage irrelevant in under-8,000 gallon pools. Cable management adds friction; cordless units more practical for compact installations. |
| Medium (400 – 800) | GoodOptimized for 12,000–25,000 gallon in-ground pools; single weekly cycle covers entire floor and waterline. | GoodOptimized for 8,000–15,000 gallon pools. Smart-mapping coverage balances runtime advantage with cable setup overhead. |
| Large (> 800)they differ | DependsPools above 25,000 gallons require 2–3 cycles per week for floor thoroughness; single cycle misses section coverage. | GoodCorded design ideal for 15,000+ gallon pools where battery-limited robots require multiple cycles or external recharging. |
| Debris load | ||
| Fine (sand / silt) | GoodMulti-layer filtration excels at algae spores and fine silt; weekly filter maintenance is sufficient. | GoodPre-filter handles sand and silt. Weekly washing maintains suction; established owner reports confirm reliable performance. |
| Leaves / large debristhey differ | DependsHandles light leaf load (10–20 per week); heavy seasonal debris clogs filter within 1–2 cycles. | GoodLeaf debris accelerates pre-filter clogging and cable entanglement risk. Monthly deep-clean and more frequent emptying required in high-leaf environments. |
| Algae / heavy foulingthey differ | DependsWaterline brush removes light algae film; thick bloom buildup (>2mm) requires manual pre-treatment. | GoodSmart-mapping and drive tracks designed for algae-laden water. Filter maintenance more frequent in bloom conditions but no known design limitations. |
| Coverage you want | ||
| Floor only | GoodFloor-mapping is primary mode; 95%+ coverage in standard in-ground layouts with consistent plaster. | GoodPrimary design focus. Systematic coverage on vinyl and plaster floors confirmed by owner reports and manufacturer specifications. |
| Floor + wallsthey differ | DependsWall climbing works up to 45° incline (standard walls); coverage is secondary to floor priority. | GoodWall-climbing verified on standard vinyl and plaster surfaces. Established 2-year track record confirms consistent vertical navigation without manual repositioning. |
| Floor + walls + waterline | DependsWaterline reach is effective on plaster; tile and raised grout lines receive uneven coverage depending on texture. | DependsWaterline brushing not integrated into autonomy model. Manual brush attachment or auxiliary device required for waterline algae. |
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.
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.
Maytronics Dolphin M600
The power supply’s button starts a cleaning cycle without a phone, so the app is not required to run the robot: scheduling, cycle-mode selection, and filter diagnostics are the functions that live only in MyDolphin Plus.
Waterline brush reaches algae film effectively, but regular (<20mm) buildup means the filter clogs weekly, the multi-layer design prioritizes fine debris at the cost of fast clogging cycles.
Polaris VRX iQ+
Unlimited runtime from corded architecture replaces battery anxiety with cable management friction and pre-session setup burden.
Onboard Sensor Nav coverage runs without a network and without anything described to it beforehand, and gives up any documented way for the owner to steer, mask or inspect the route it takes.
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.
Maytronics Dolphin M600
- Above-ground pools and smaller portable installations
- Design assumes fixed cable anchoring and floor-wall transitions common to in-ground pools. Above-ground liners and perimeter walls differ structurally; dock positioning becomes problematic.
- Pools with heavy leaf load or thick algae blocking waterline
- Multi-layer filter clogs faster with high debris. Waterline brush cannot penetrate algae layers thicker than ~2mm; manual pre-treatment required, negating automation benefit.
- Owners unwilling to reposition cable seasonally or manage swivel maintenance
- Climate swings require cable repositioning to prevent tangling; northern climates need winterization steps. Swivel maintenance every 6–12 months is non-negotiable for reliability.
- Plaster pools with severe erosion or rough patina
- Navigation assumes consistent floor texture; severely eroded plaster causes the unit to lose positional accuracy and miss sections. May over-brush thin patches accelerating wear.
- Pools without a GFCI-protected outlet within cable reach
- The M600 runs from a power supply that sits on the deck and plugs into a standard 120 V outlet, with a low-voltage cable to the robot. That outlet has to be GFCI-protected, which electrical code requires near a pool, and the supply plugs directly into it rather than through an extension cord. A pool whose only power is out of reach needs electrical work before the robot is usable.
Polaris VRX iQ+
- Cable-averse owners or tight equipment storage
- Tether handling is part of every session, and 70 feet of cable needs somewhere to live between runs. Cordless cleaners remove that step in exchange for a runtime bounded by charge.
- Pools with complex geometry or non-standard features
- Smart-mapping optimized for rectangular/oval layouts. Kidney shapes, spas, or bubblers cause coverage gaps. Manufacturer documentation cites unreliable calibration in complex pools.
- Households wanting a cleaner that lives in the pool
- The cleaner and its cable come out of the water between runs and before anyone swims, so every cycle is handled at both ends. The Easy Lift system shortens the job but does not remove it.
- Pools longer than the 60 foot rating
- The VRX iQ+ is rated for in-ground pools up to 60 feet in length. Longer pools and commercial water sit outside what the cleaner and its 70 foot cable are specified to cover.
- Owners seeking true set-and-forget operation
- Weekly filter cleaning, monthly cable swivel inspection, and seasonal cartridge replacement required. Not autonomous enough for minimal-effort schedules.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Maytronics Dolphin M600
- After every use: Empty debris basket from filter housing; rinse with hose.
- Weekly: Inspect dual-brush bristles for algae or hair; clean bristles with brush tool if matted.
- Weekly: Check filter media for visible clogging; rinse filter cartridge if water flow slows.
- Monthly: Inspect cable swivel for tangling; manually unwind if cable shows twist pattern.
- Every 3-6 months: Clean motor brush contacts with dry cloth; inspect brush wear depth (~10 minute task).
- Seasonally: In freezing climates, remove cable from pool and drain completely before first freeze.
- Annually: Replace filter media cartridge (~$35–45); inspect and lubricate swivel assembly ($0 DIY, or $60 replacement if needed).
Polaris VRX iQ+
- After every use: Lift the cleaner out with the Easy Lift system, empty the 5 L canister and rinse the filter media.
- Weekly: Rinse the canister and media thoroughly, and check the cable and swivel for twists and trapped debris.
- Monthly: Inspect the drive tracks and brushes for sediment, hair and wear, and check the cable jacket for abrasion.
- Seasonally: Replace the filter media when rinsing no longer restores flow, and replace the cable swivel if it stiffens or leaks. Polaris Pool publishes no interval or price for either.
- For winter storage: Rinse the cleaner with fresh water, dry it, coil the cable loosely and store the cleaner and the power supply indoors. The motors are sealed against water; there is no bearing lubrication step and no seal an owner opens.
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.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
