Best cordless robotic pool cleaner in Australia

Prices, runtimes and warranty terms checked 5 September 2026

Cordless is now the default in this category rather than the premium option: 38 of the 66 cleaners we track run on a battery, and they start below $600. This page compares all of them on the figures manufacturers actually publish, and is direct about the one figure none of them publish.

We have not run these machines in a test pool and do not present this as a test. What we do is compile published specifications, verify Australian prices at the retailer on a stated date, and document who honours the warranty here. Where a brand publishes nothing, the table says "not published" rather than filling the gap.

Which one, by situation

Small pool, tight budget

7 cordless models sell under $1,000, from $500 up. At this end the question is not which cleans best, it is whether anyone here will repair it. Several of the cheapest units come from brands with no Australian company, no ABN and no named repair address, which turns the machine into a consumable. That is a defensible buy on a $500 unit and a poor one at $1,500.

You want the waterline done

The greasy tide-mark at the waterline is the job a suction or pressure cleaner cannot do, and it is the main reason to move up from an entry robot. 20 cordless models under $2,000 publish waterline cleaning, so this stopped being a premium feature some time ago. Read the fine print though: at least one brand's own comparison table marks a model as reaching the waterline while separately marking horizontal waterline scrubbing as absent, which are two different capabilities sold under one word.

Long cycles and big pools

The longest published runtime in the set is the Beatbot AquaSense 2 Pro at 11 hours, at $3,599. Runtime and pool-size rating are the two specs to weigh together here, because a machine that runs out mid-cycle on a large pool has effectively cleaned half a pool. Our specification register lists the pool rating each manufacturer publishes, in the units they publish it in.

Lowest risk

A Dolphin, and not because of the spec sheet. Cordless Dolphins start at $1,899 with the Dolphin Eon 100, which is more than the cheapest cordless machines here by a wide margin. What the money buys is Maytronics Australia Pty Ltd, a registered Australian company with a head office in Oxley, an authorised service network and a published phone number. We earn nothing on Dolphin, which is worth stating given how often this site points at it.

The conflict, stated plainly

Of the five brands on this page, the only one that runs an affiliate program open to us is Wybot, and it is also the one with the thinnest Australian support. Its Australian storefront publishes no Australian entity, no ABN and an empty warranty page, and neither of the two largest specialist retail chains carries the brand. Dolphin pays us nothing and has the strongest local service presence in the category. We have not resolved that tension by quietly dropping either brand, and you should weigh the tables above knowing it exists.

What cordless does not change

Running cost. A robotic cleaner of either kind uses roughly $4.86 to $7.85 of electricity across a full season depending on your state tariff, against about $358 a year for the filtration pump. That is close to a rounding error on a pool, and it should not influence which model you buy. The running-cost register shows the arithmetic and every input.

Warranty is the other thing cordless does not decide. Terms in this set run from one to four years and they do not track price: the most expensive cordless robot in the register carries two years and no Australian service network, while a machine at the same price from another brand carries four years and a national dealer network. The warranty register sets out who actually repairs each brand here.

The three questions to ask before you pay

• Is a replacement battery sold in Australia, and what does it cost? A retailer who answers with a part number and a price is selling you a repairable machine.
• What does the runtime figure cover? Ask whether it is quoted on floor-only mode. It almost always is.
• Who repairs it, and where does it go? If the answer is an overseas warehouse, factor the freight and the weeks without a cleaner into the price.

Common questions

Is a cordless robotic pool cleaner better than a corded one?

Not automatically. Cordless removes the floating cable, which is the single most irritating thing about a corded robot, and it lets you drop the machine in without being near a power point. What you give up is a consumable part: a battery that degrades and, on most models, cannot be replaced by you. Of the 66 cleaners we track, 38 are cordless and 28 are corded, so both categories are well represented at every price.

How long does a cordless pool cleaner run for?

Published runtimes across the models sold here run from about 1 to 11 hours. That figure is quoted on the gentlest cleaning mode, usually floor-only in a smooth pool, so a full floor, wall and waterline cycle will always finish sooner than the headline number suggests.

What happens when the battery dies?

On most cordless models the pack is sealed inside the housing and is not a user-serviceable part. No manufacturer selling into Australia publishes a cycle-life figure, so there is no sourced answer to how many seasons you get. Before you buy, ask the retailer whether a replacement pack is sold separately in Australia and what it costs. If they cannot answer, you are buying a machine with an undisclosed expiry date.

Does cordless cost more to run?

No, and the difference is too small to matter either way. A robotic cleaner uses roughly $4.86 to $7.85 of electricity across a full swimming season depending on your state, against about $358 a year for the filtration pump. Running cost should not decide which cleaner you buy. Whether anyone in Australia repairs it should.
