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 | Hayward AquaVac 650 | Dolphin Liberty 600 |
|---|---|---|
| Pool type | ||
| In-ground | GoodDesigned for in-ground gunite/plaster pools; dock placement requires dedicated 110V outlet and 10-foot clearance. | GoodDesigned exclusively for in-ground pools with perimeter access for dock placement. |
| Above-ground | PoorBrush geometry and dock coupling target in-ground installations; vinyl walls not compatible with HexDrive pads. | PoorNot designed for above-ground pools; dock stability and electrical exposure are concerns. |
| Mixed setup | GoodStandard for this category, see specs for confirmation. | GoodIn-ground pools only; confirm dock can be placed near pump or pool edge safely. |
| Pool size | ||
| Small (< 400 sqft) | GoodCapable but overkill for pools under 8,000 gallons; smaller battery-powered units offer better cost alignment. | GoodFull feature set (waterline + floor + wall) overkill for under 8,000 gallons; a smaller cordless model would be lower cost. |
| Medium (400 – 800) | GoodIdeal target: 12k–18k gallons. Two-hour runtime covers a single session without battery strain. | Good12,000–25,000 gallons is the designed envelope; one 90-minute cycle achieves full three-plane coverage. |
| Large (> 800) | DependsConsecutive sessions required for 20k+ gallon pools; multiple cycles per week increase dock-seal wear patterns. | Depends30,000+ gallon pools require 110+ minutes for three-plane coverage; two cycles or battery replacement mid-session recommended. |
| Debris load | ||
| Fine (sand / silt) | GoodPleated intake filter handles silt and algae detritus effectively; weekly rinse prevents clogging. | GoodFine sediment handled well; filter cartridge rinses easily after fine-sediment sessions. |
| Leaves / large debris | Good18L debris bin covers heavy autumn load; daily empties typical in peak seasons. | GoodBattery limits runtime in high-debris scenarios; pre-skim pool during fall to avoid basket clogs and runtime depletion. |
| Algae / heavy foulingthey differ | DependsWaterline brush targets surface-film algae well; free-floating algae requires pre-filtration. | GoodWaterline jet addresses algae at tile line; floor and wall coverage complete. Light biofilm handled in one pass. |
| Coverage you want | ||
| Floor onlythey differ | DependsCapable but this robot targets floor + waterline; wall coverage requires manual intervention. | GoodComplete floor coverage; floor-only mode available in app to conserve battery. |
| Floor + wallsthey differ | PoorHexDrive geometry does not reach vertical walls; only floor and waterline are documented. | GoodWall climbing and floor coverage integrated; wall-return engagement automatic. |
| Floor + walls + waterlinethey differ | PoorWaterline reach is documented; wall coverage and suction line pathing are not autonomous. | GoodWaterline jet is included; covers tile line in dedicated 15–25 minute cycle within full 90-minute runtime. |
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.
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.
Hayward AquaVac 650
Mains power removes any runtime ceiling, so a full floor, wall and waterline cycle runs to completion in one pass, but the 55 ft cord has to be paid out and retrieved at every session.
SpinTech separation takes the filter cartridge out of the ownership cost entirely, but debris still has to be emptied from the canister by hand after each cycle.
Maytronics Dolphin Liberty 600
Cordless operation removes cable management, but coverage is bounded by charge rather than by the wall socket. Maytronics states up to 4.5 hours per charge, and Eco Mode spreads that across scheduled short cycles instead of one continuous pass.
App control enables sophisticated scheduling but requires WiFi stability and smartphone ownership; network outages silence scheduled runs without alert.
ClickUp removes the cable and brings the cleaner to the surface on its own, but retrieval is still manual: the owner lifts the unit out of the water by hand at the end of every cycle.
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.
Hayward AquaVac 650
- Pools larger than 20 ft by 40 ft
- Hayward rates the AquaVac 650 up to 20 ft by 40 ft. Larger pools fall outside the published sizing, and the 55 ft cord bounds how far the cleaner can work from the power supply.
- Owners wanting zero app setup
- First deployment requires a Hayward app account and Wi-Fi pairing before scheduling and remote mode selection are available.
- Owners who want a cordless cleaner
- The AquaVac 650 is corded. A 55 ft cord runs from the poolside power supply to the cleaner and has to be paid out, retrieved and coiled onto the caddy at each session.
Maytronics Dolphin Liberty 600
- Owners prioritizing hands-off operation without app dependency
- Liberty 600 requires mobile app for scheduling. Manual start button exists but full scheduling requires smartphone connectivity and app engagement. WiFi outages halt scheduled runs.
- Pools with heavy fall leaf debris
- Debris capacity is fixed, so a heavy leaf load has to be emptied more often than the cleaning schedule alone would require. Pre-skimming reduces how often a cycle is interrupted during high-debris seasons.
- Pools longer than 50 ft
- Maytronics rates the Liberty 600 for pools up to 50 ft. Longer pools fall outside the published sizing.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Hayward AquaVac 650
- After every use: Release the TouchFree canister and empty it; rinse the canister and the cleaner’s intake. SpinTech separation uses no filter cartridge, so there is nothing to replace on a schedule.
- Weekly: Rinse the rollers to clear algae residue and check them for embedded grit.
- Every 3-6 months: Inspect the rollers for wear and replace when the tread is gone. Hayward publishes no replacement interval or price.
- Seasonally: Rinse the cleaner with fresh water at pool close, coil the cord onto the caddy, and store the unit and its power supply indoors in freeze-zone climates.
Maytronics Dolphin Liberty 600
- After every use: Empty and rinse the debris basket; air-dry the cleaner before storage.
- Weekly: Check the brushes and the impeller intake for hair, string and leaf stems.
- Monthly: Inspect the battery pack and its contacts for damage or mineral deposits; rinse the basket screens through.
- Seasonally: Deep-clean the basket and brushes at pool open and close; store the cleaner and its battery indoors over winter in freeze-zone climates.
- As needed: Replace brushes when worn. Maytronics publishes no replacement interval or price for this model.
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.
