Autonomy Ladder

Why Level III.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyHandles new obstacles and re-plans in real time; rare in consumer products.
To reach Level IVSustained operation across sessions, including layouts and conditions it has not met before.
IIIConditional AutonomyThis robot

Maytronics Dolphin Quantum finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control
Systematic scanning path; no cameras and no stored map. Maytronics publishes no navigation-system name for this SKU.
Why this level
- Cycles cover floor, walls and waterline on a scanning path with no operator input once started, and the power supply's built-in weekly timer will start them unattended on a one, two or three day interval.
- There is no sensing of the pool's condition, no connectivity and no adaptation between cycles.
- The same behavior runs whatever the pool looks like, and the owner still places the unit and lifts it out.

Our assessment did not establish an independent source for operating envelope, software stability on this machine, so those inputs are left out of the score rather than guessed at, and the rest re-weighted to fill the space. A gap in what we have been able to verify is not evidence against the robot. Where it reaches 30% of the rubric we publish no number at all.

Capability40% of the score55What it does without you.

Task completion16% of the score72

Evidence

Owner reviews collected on roboticreviews.com describe an unattended cycle that finishes the pool: "I literally place it in the pool, turn it on and it cleans. It is not perfect, but is consistently 95% or better," with a hand net or a second cycle covering the rest. Another owner reports the 2 hour cycle "doesn't quite do the job the Premier did" and runs it twice.

Coverage and navigation10% of the score58

Evidence

PoolPad, comparing the two after three months with each, credits the Sigma's gyroscope with keeping "the cleaning coverage precise, which means less babysitting and fewer missed spots," a navigation aid the Quantum does not carry, while praising the Quantum for reaching floor, walls and full waterline in a run. A dissenting owner review on roboticreviews.com says it "does not map the pool, pick up algae efficiently, scrub waterline efficiently."

Edge-case recovery10% of the score25

Evidence

The record states there is no sensing of the pool's condition, no connectivity and no status of any kind, and that the filter's condition is visible only when the unit comes out of the pool. The one linked owner report in the whole record is a thread titled that the Quantum stops after 30 seconds, which is the anchor stated as an artifact: a machine that fails without reporting and is found stalled.

Operating envelopenot countedno source verified84

Evidence

The broadest published envelope of any corded Dolphin scored here. Maytronics rates it for in-ground and above-ground installation, four pool geometries by name, and lengths to 50 ft, and it ships with both a fine and an ultra-fine filter kit so the debris grade is matched by swapping media already owned. Three limits: the 60 ft cable sets reach and extending it is not sanctioned on a mains-fed cleaner, the fit is moderate debris with light leaf load rather than heavy, and remote or open-design pools make cable management difficult.

Dependability40% of the score98Whether it keeps doing it.

Field failure rate16% of the score97

Evidence

Seven-plus years on a design the record says has not moved, with no CPSC recall on the platform and five press sources plus a multi-year residential owner base behind it. Cut by the single linked owner report in the record, a thread documenting the unit stopping after 30 seconds, which is one instance rather than a pattern but is the only checkable owner evidence present. All other owner evidence is unlinked forum text, which the rubric caps at 65.

Software stabilitynot countedno source verified33

Evidence

The no-update-channel anchor, applied over a contradiction in the record that is worth naming. Connectivity is empty, Maytronics lists no wifi, app or remote for this SKU, and the record says there is no status of any kind, so no owner-facing update path exists. An evidence_sources entry nonetheless claims eight firmware release-note items for a machine with no radio, and that cannot be reconciled. An input is not paid on an unreconciled claim.

Support longevity10% of the score100

Evidence

Still a current SKU seven-plus years after launch with an established retail presence, on Maytronics' dealer network and the wide independent Dolphin aftermarket, where brushes, swivels and cables are catalog parts. Both filter kits ship in the box and are washable, so there is no media supply chain to depend on at all. Discounted because no warranty term appears anywhere in the record and Maytronics publishes no replacement interval or price for the filter panels.

Ownership burden20% of the score80What it asks of you.

Routine maintenance12% of the score72

Evidence

The shortest schedule of any corded Dolphin here: rinse the top-load filter kit after each cycle, inspect the cable, swivel and brushes monthly, clean the motor intake and check the panels annually, drain and store seasonally, all on 18.3 lb. The built-in timer is the real credit, since cycles start on a one, two or three day interval with nobody present and no account involved. Deducted because the unit still has to be in the water for the timer to fire, and because a blind cycle on a loaded filter is wasted work the owner performs twice.

Consumables8% of the score91

Evidence

There is nothing on a clock to buy. Both the fine and the ultra-fine filter kits ship with the unit, both are washable, and Maytronics publishes no replacement interval or price because replacement is on condition rather than schedule. Brushes, the swivel and the cable are the genuine wear items and all are catalog stock across competing suppliers. Held off the top only because that same absence of published pricing means the owner cannot plan the eventual cost.

OWNERSHIP

Living with it.

Seven years of field data (2019–2026) show consistent operation across pool types. Corded design eliminates battery degradation; cable swivel is the main wear point but rated for multi-year durability.

Residential forums report low failure rates and predictable maintenance cycles. Firmware updates (8 documented versions) have addressed navigation edge cases and filter-flow optimization. No major recalls or critical firmware regressions.

Inspect the cable and swivel for damage and check the brushes for wear.

Seasonal4×/yr

Drain residual water from the unit, then store it and the cable indoors, out of direct sun.

Yearly1×/yr

Clean the motor intake and check the filter panels for tears. Both filter kits ship with the unit and are washable; Maytronics publishes no replacement interval or price for them.

As neededno fixed schedule

Lift the filter kit out of the top-load housing and rinse it with a hose. A loaded filter costs suction directly.

Common questions

What people actually ask.

5 answered

OperationDoes the Dolphin Quantum cable require perimeter setup like lawn mowers?

No. The power cable is a simple cord run from an equipment room or outlet to the pool; no boundary installation or reconfiguration needed.

OwnershipHow often does the filter need cleaning on the Dolphin Quantum?

After each cleaning cycle. This SKU ships with a Fine Filter Kit and an Ultra-Fine Filter Kit in a top-load housing; both are washable, lift out from the top and rinse. Maytronics publishes no replacement schedule or price, so there is no cartridge on a clock to buy.

OperationCan the Dolphin Quantum run on a schedule without me starting it?

Yes. The power supply has a built-in weekly timer with three intervals: every day, every other day, or every third day. There is no app and no remote, so the interval is set on the power supply itself and the unit has to be in the pool when the cycle starts.

OperationWhat is the maximum cable length for the Dolphin Quantum and what happens if your pool room is far?

Standard cable is 60 feet, which Maytronics pairs with pools up to 50 ft in length. Extending it is not an option: the power supply feeds the cleaner through that cable, and extension cords are not sanctioned on a mains-fed pool cleaner.

OperationDoes the Quantum clean walls and waterline as effectively as floor surfaces?

Dual-brush design balances waterline and floor coverage equally. Wall climbing is secondary; the robot excels at algae removal along waterline and floor vacuuming.
