How we chose
We assessed current Australian models, exact local SKUs, pool-size suitability, floor/wall/waterline coverage, steps and ledges, filtration, debris handling, navigation, cycle length, cord or battery ownership, retrieval, servicing, warranty, pricing, exact-model owner evidence and credible manufacturer documentation. A higher score does not automatically make a product right for every pool.
Worth Buying scores are editorial judgements, not customer ratings. We did not combine owner pools or treat manufacturer performance claims as independent measurements.
Serious contenders
Dolphin M700, around $3,999, adds sophistication but costs more than M600 without a proportionate value gain for most residential buyers. Exact Australian owner evidence includes both strong satisfaction and material complaints about Wi-Fi, cleaning behaviour and support; that does not make it universally poor.
Beatbot AquaSense 2 Ultra, around $4,899 on sale from $5,999, combines surface skimming, floor/wall/waterline cleaning, advanced navigation and retrieval. Direct Australian stock was sold out during research, though that does not prove it unavailable everywhere, and its price and complexity restrict broad appeal. AquaSense 2 at about $1,999 and 2 Pro at about $3,599 are strong alternatives, but do not displace SPINO on value or Liberty on mature local service. Current premium Aiper models also remain relevant where exact-model Australian stock and support are convincing.
Why two Dolphins remain
M600 and Liberty 600 solve different needs: the M600 is the corded, continuous-power, established all-rounder; Liberty 600 is the premium cable-free convenience choice. SPINO E1 adds a much lower entry price. Brand diversity was not forced at the expense of clearer buyer roles.
Maytronics Dolphin M600 · 99996650-AU
The exact Australian 99996650-AU is designed for residential pools up to 15m and cleans the floor, walls and waterline. Dual-drive mobility, CleverClean navigation, PowerStream movement and active scrubbing target broad coverage, while a large top-load multi-layer basket provides fine and ultra-fine filtration.
MyDolphin Plus adds Wi-Fi control, multiple cleaning modes, filter indication and pick-up mode. Cycle choices run roughly one to 2.5 hours depending on the selected program. A caddy is included, and Maytronics backs the Australian model with a three-year warranty.
The 17m swivel cable reduces tangling risk but does not guarantee tangle-free ownership. Straightening it, avoiding tight storage coils and using the caddy according to Maytronics guidance matter. The robot weighs about 11.5kg dry and feels heavier before retained water drains.
Exact M600 feedback on ProductReview within the Dolphin M-Line grouping repeatedly supports useful leaf and fine-debris removal, wall/waterline cleaning and reduced manual work. Reported negatives include cable twist, app connectivity, basket handling and multi-year wear items. These are owner themes, not universal defects, and no M700 or M400 score has been merged into an M600 rating.

Mammotion SPINO E1
Mammotion Australia lists SPINO E1 for pool areas up to 150m² with up to 3.5 hours of claimed runtime. It covers floors, walls and the waterline, uses SmartArc path planning and a triple brushless-motor system, and eliminates an in-pool power cable.
The 5,800 GPH figure is Mammotion's suction-flow claim, not an independent measure of cleaning quality. Runtime also depends on pool shape, debris, mode, surface and battery condition. Longer runtime alone cannot prove better cleaning because path efficiency, brushes and filtration matter just as much.
At $899 promotional pricing, down from a regular $1,099, SPINO is dramatically cheaper than the two Dolphins. That standout price may end. Its recommendation rests on the verified local model, broad stated coverage and value—not a mature owner history or borrowed reviews from Mammotion robot mowers and other SPINO products.
The battery is a consumable component over long ownership. Runtime can decline, and replacement cost, supply and authorised serviceability should be checked. Mammotion's current Australian warranty is two years, while the brand's local pool-cleaner servicing depth is less established than Maytronics.

Maytronics Dolphin Liberty 600 · 99998600-AU
The residential Australian 99998600-AU suits pools up to 15m and runs for up to 4.5 hours. Jet Powered Steps Cleaning and sun-ledge coverage distinguish it from cordless models that focus mainly on floors and walls, though no robot can promise perfect results on every shelf, corner or unusual geometry.
A 4.5L top-load multi-layer basket handles fine and ultra-fine filtration. Maytronics One supports Wi-Fi and Bluetooth control, while Homing, Click-Up and Click-To-Stop make retrieval more deliberate than simply waiting for a flat battery.
Advanced Eco Mode can divide maintenance sessions across up to two weeks from one charge under defined schedules. It does not run continuously for two weeks. Every session still consumes battery capacity and the 4.5-hour maximum remains condition-dependent.
The robot weighs about 12kg dry, costs $3,299 and carries a three-year residential warranty. Charging adds a workflow that M600 avoids, and future battery and charger costs remain part of ownership. This is the residential Liberty 600, not the commercial Wave Liberty 600; commercial specifications and warranty terms have not been transferred.

What matters when buying a robot pool cleaner
Corded versus cordless
Corded robots provide effectively unlimited runtime, consistent power and no battery degradation, but require cable handling, storage and retrieval. Cordless models remove the cable and simplify poolside deployment, but introduce charging, finite runtime, battery ageing and future replacement cost. Neither is universally better.
Pool coverage
Floor-only, floor-and-wall, and floor/wall/waterline cleaning are distinct capabilities. Narrow steps, shallow shelves, bench seats and unusual geometry remain harder. Wall climbing does not guarantee perfect step or ledge cleaning, even where a model has specialist features.
Filtration and debris
Sand, dust and silt need fine media; leaves, twigs and seed pods need accessible capacity. A large basket does not automatically deliver better fine filtration. M600 and Liberty 600 stand out for multi-layer fine and ultra-fine systems.
Navigation limits
Pool robots combine algorithms, sensors, gyroscopes, wall detection and path planning. They do not map every pool like a premium indoor robot vacuum. Good units can revisit areas, miss corners or struggle around drains and complex steps.
Battery ownership
Lithium-ion batteries are consumables. Runtime can decline with age, so replacement cost, availability and authorised service matter. Do not assume a cordless robot will retain its original runtime indefinitely.
Cycle length
Longer runtime does not automatically mean better cleaning. Brushes, filtration, suction or flow, path efficiency, pool shape and debris type all affect the result. Choose capacity and coverage for the pool rather than ranking by hours alone.
Cable management
M600's swivel reduces tangling risk but cannot eliminate it. Straighten the cable, avoid tight coils and use the supplied caddy according to Maytronics guidance. Damaged cables and power supplies require authorised inspection rather than improvised repair.
Robots do not replace pool filtration
A robot removes settled and attached debris, but does not replace circulation, sanitisation, chemical balance or the pool's main filtration system. Continue the maintenance schedule appropriate to the pool and local conditions.
Safety around water, power and batteries
Follow the manufacturer’s electrical instructions and use only the supplied power or charging system. Do not swim while the cleaner operates where guidance prohibits it. Remove the cleaner and isolate power before servicing accessible areas; never modify a power supply or bypass a safety system. Inspect cables and connectors for damage. Charge cordless models only as directed, do not use a damaged lithium battery, and follow storage and charging temperature guidance. Never open a battery pack.
Which robot pool cleaner should you buy?
Choose the Dolphin M600 if you want the strongest proven all-round cleaner, mature support and continuous mains-derived power, and can tolerate cable management.
Choose the Mammotion SPINO E1 if you want affordable cordless convenience and accept a newer product with a shorter exact-model ownership record.
Choose the Dolphin Liberty 600 if you want premium cordless operation, stronger step and ledge functionality, sophisticated retrieval and mature Australian service support.
Frequently asked questions
Are cordless pool robots better than corded ones?
Not automatically. Cordless models remove cable hassle, while corded models avoid charging, battery ageing and finite runtime. Pool geometry, debris, filtration, support and the owner's tolerance for cable handling decide which compromise is better.
Do robot pool cleaners clean walls and the waterline?
Some do, including all three recommendations here, but floor-only models still exist. Surface material, shape and water chemistry affect climbing, and no robot is guaranteed to cover every corner equally.
Can robot pool cleaners clean steps and ledges?
Some can attempt them, but shallow shelves, narrow steps and unusual geometry remain difficult. Liberty 600 explicitly targets steps and sun ledges; that still is not a promise of perfect coverage in every pool.
How long do cordless pool-cleaner batteries last?
Cycle runtime may range from a few hours, but service life depends on charge cycles, heat, storage and use. Capacity normally declines over time. Check authorised replacement availability and cost before buying.
Do robotic pool cleaners replace your pool filtration system?
No. They collect debris from pool surfaces but do not replace circulation, chemical treatment, sanitisation or the main filter. Both systems have different jobs.
How often should you run a robotic pool cleaner?
It depends on leaves, dust, weather, pool use and filtration. Several sessions a week may suit some pools, while others need less. Start with manufacturer guidance, inspect the result and empty or clean the basket after use as directed.
