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 Liberty 300 |
|---|---|
| Pool type | |
| In-ground | GoodMagnetic dock and climbing capability optimized for standard in-ground installations. |
| Above-ground | PoorCordless form factor and dock design not suited to above-ground frame geometries. |
| Mixed setup | GoodStandard cordless pool cleaner fit for any standard pool type. |
| Pool size | |
| Small (< 400 sqft) | GoodBelow documented range; cordless design and dock footprint may exceed needs for pools under 8,000 gallons. |
| Medium (400 – 800) | GoodManufacturer-targeted range of 12,000-20,000 gallons; runtime and coverage align with medium pool cycle expectations. |
| Large (> 800) | DependsPools above 25,000 gallons may require multiple charge cycles per pass; heavy debris load shortens cartridge intervals. |
| Debris load | |
| Fine (sand / silt) | GoodFilter-cartridge design handles fine sediment; weekly rinse maintains suction for sand and silt. |
| Leaves / large debris | DependsCartridge clogging accelerates with heavy leaf fall; pre-skimming recommended during peak shedding season. |
| Algae / heavy fouling | DependsCleaner removes settled algae; active algae blooms require chemical treatment. Cartridge washings increase with algae frequency. |
| Coverage you want | |
| Floor only | GoodPrimary documented function with predictable floor coverage per cycle. |
| Floor + walls | GoodWall-climbing capability documented; sustained waterline reach varies by pool condition and cleaner pitch. |
| Floor + walls + waterline | DependsWaterline brush reach documented but performance on calcium buildup and algae line varies; depends on pool chemistry. |
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.

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.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
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 Liberty 300
Cordless convenience comes with battery discipline. The pack goes into winter storage charged and gets topped up during the off-season, and between cycles the unit is lifted out and charged by hand rather than returning to a dock.
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 Liberty 300
- Pools with a heavy leaf load
- Coverage per charge is bounded by the battery, and published cycle length is itself in dispute (Maytronics lists 2.5 hours, a hands-on review reports 1.5). A heavy debris load also fills the basket sooner, and the basket cannot be emptied without lifting the unit out of the water.
- Pools where lifting the unit out at the edge is awkward
- The Liberty 300 has to come out of the water to charge, and the sound-activated retrieval only brings it to the wall. Deck height, coping and reach decide how much of a chore that is.
- Owners requiring hands-off scheduling year-round
- This SKU has no Wi-Fi, app or schedule, and no dock to return to. Every cycle is started at the unit and ended by lifting it out; charge maintenance and off-season storage stay with the owner.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Maytronics Dolphin Liberty 300
- After every cycle: Lift the filter panels out of the top-access basket and rinse them with fresh water; check the brushes for wrapped debris.
- Monthly: Wipe the magnetic charging contacts on the unit and on the charger so they seat cleanly.
- Every 3-6 months: Check the drive tracks and brushes for wear. The drive and pump motors are sealed units; noise or vibration is a service-center matter, not an owner procedure.
- Seasonally: Store the unit charged and indoors, and top the battery up during the off-season. Storing a lithium pack discharged damages it.
- Annually: Inspect the filter panels for tears and the charger lead for damage.
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 |

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.
