Complete Guide to Robotic Pool Cleaners in Australia

A robotic pool cleaner takes care of the jobs that usually end up at the bottom of the pool maintenance list. It moves across the pool floor, climbs the walls and, on suitable models, cleans along the waterline while scrubbing surfaces and collecting debris in its own filter basket.

Unlike suction and pressure cleaners, a robotic pool cleaner has its own motor, filter and navigation system. It does not rely on the pool's main pump to move around the pool.

That makes it a practical option for Australian backyard pools, particularly during the warmer months when the pool is being used regularly and leaves, dust, pollen and other debris can quickly build up.

A robotic cleaner will not balance your pool water, remove an active algae bloom or replace a surface skimmer. What it does well is take care of the physical cleaning that would otherwise mean brushing, vacuuming and emptying the pool by hand.

This guide looks at whether a robotic pool cleaner is worth buying, how to choose the right type for your pool, which features actually matter and what to expect when it comes to price, maintenance and ownership.

Is a Robotic Pool Cleaner Worth It?

For a pool that gets regular use throughout the swimming season, a robotic pool cleaner can pay for itself over time by reducing professional pool servicing or the amount of time spent cleaning the pool yourself. If the pool is only used occasionally, the calculation is different. There may simply not be enough cleaning work to justify the extra expense. The real question is fairly simple: how much ongoing work or servicing cost will the cleaner replace?

A season of weekly professional pool servicing can cost more than a mid-range robotic cleaner. If the robot replaces some or all of that work, the value becomes much easier to see.

Who tends to benefit

A robotic cleaner makes particular sense for:

• Owners of in-ground pools

• Larger above-ground pools

• Pools surrounded by trees or gardens

• Pools that collect a lot of leaves and pollen

• Families using the pool several times a week

• Pool owners who are tired of vacuuming manually

• Households that currently pay for regular pool cleaning

Australian backyards can also be particularly demanding on pool cleaning equipment. A pool under gum trees, near garden beds or exposed to wind can pick up a surprising amount of leaves, fine dust and organic debris.

In those situations, the cleaner is replacing a job that needs doing again and again rather than simply being another piece of pool equipment.

Who may not need one yet

A robotic cleaner is not necessarily worth buying for every pool. Small inflatable pools, soft-sided temporary pools and pools that are only used a handful of times each season may not justify the cost. It is also important not to expect a robotic cleaner to solve water-quality problems. A robotic pool cleaner does not balance pH, correct chlorine levels or fix green water. It can collect dead algae and settled debris after treatment, but an active algae problem needs to be dealt with through proper pool chemistry first.

How to Choose a Robotic Pool Cleaner

Most problems with a robotic pool cleaner can be avoided by checking a few things before buying. The size and shape of the pool matter. So do the surface material, debris load, wall and waterline requirements, battery capacity and how much maintenance you are prepared to do.

A useful starting point is the robotic pool cleaner buying guide.

Above-ground or in-ground pool

The first thing to check is what type of pool you have.

Above-ground pools generally have softer walls, flatter floors and different weight requirements. An in-ground pool can have a deep end, slopes, steps, ledges and more complicated surfaces. If you have an in-ground pool, wall climbing is particularly important. A cleaner designed only for above-ground use may handle the floor but struggle to climb the walls or reach the waterline. This is one of the most common mistakes first-time buyers make: choosing a cleaner based on price without checking whether it is designed for the pool itself.

For a more detailed comparison, see The Guide to Robotic Pool Cleaners for Above-Ground Pools in Australia.

Pool size and shape

Pool size affects how long a cleaning cycle needs to run. A small backyard pool may complete a cycle in well under two hours. A standard family-sized in-ground pool will need longer, particularly if the cleaner is covering the floor, walls and waterline. Larger pools need enough battery capacity to complete a useful cleaning cycle without stopping halfway through to recharge.

Pool shape is just as important. A straightforward rectangular pool is relatively easy for most navigation systems to cover. Kidney-shaped and free-form pools, sun shelves, tanning ledges and pools with several groups of steps are more demanding.

If the pool has a complicated layout, basic random or S-pattern navigation may leave areas untouched. Infrared and IMU-based mapping can provide better coverage, while AI vision becomes more useful on pools with particularly complicated features.

Cordless or corded

For most residential buyers, cordless cleaners are now the more convenient option. There is no power cable running across the pool deck and no cable to become wrapped around a ladder or other pool equipment. You put the cleaner in the pool, start the cycle and remove it when it has finished.

The trade-off is the battery. Like any rechargeable battery, it will gradually lose capacity over time. Corded cleaners do not have that particular limitation and can continue running from a continuous power supply. The downside is dealing with the cable during operation and storage. For a more detailed comparison, see cordless vs corded pool cleaners.

Pool surface material

The pool surface should also be checked before buying. Vinyl liners generally suit cleaners with softer brush surfaces and wheels or tracks that minimise scuffing. Fibreglass and concrete pools can generally handle more aggressive brushing. Mosaic and tiled pools need a little more care around the waterline, particularly where grout is involved. A cleaner may be compatible with the surface while still requiring the correct brush and traction system for long-term use. Always check the manufacturer's surface compatibility rather than relying on the cleaner's appearance or price.

What sort of debris does your pool collect?

Think about what actually ends up in your pool. A pool surrounded by trees may collect leaves, small twigs and other larger debris. A pool exposed to dry weather and garden areas may collect fine dust and pollen. A busy family pool can also accumulate sunscreen, body oils and other residue around the waterline. Large leaves and debris mainly create a basket-capacity issue. A larger basket, around 4 litres or more, means fewer interruptions to empty it. Fine dust and pollen are more about filtration. A finer secondary filter layer in the 60–100 micron range can capture particles that a standard 180-micron filter may allow through.

Do you need waterline cleaning?

The waterline is where the water meets the pool wall, and it is often where sunscreen, body oils and fine dust collect. It is also one of the most noticeable areas when the pool needs cleaning.  A floor-only cleaner can leave this ring untouched, meaning you still need to get out the pool brush. For a pool that is used regularly, floor, wall and waterline coverage is generally the better choice. A floor-only cleaner can still make sense for a smaller pool or one that does not develop much build-up around the waterline.

How much maintenance are you prepared to do?

A robotic pool cleaner is low-maintenance, but it is not maintenance-free. The filter basket needs regular rinsing. Brushes and tracks eventually wear out, and cordless models will eventually need a battery replacement. One feature that is often overlooked is how easy the basket is to remove. Top-load baskets are generally easier to live with because they can be lifted straight out, emptied and rinsed with a hose. With a bottom-load design, you need to turn the cleaner over to access the debris. A clogged basket is also one of the most common reasons a cleaner that previously worked well suddenly appears to have weak suction.

How to read the four core specifications

Four specifications tend to dominate robotic pool cleaner comparisons: flow, runtime, filtration and basket capacity. Each one needs to be considered in context. Suction flow is commonly listed in m³/h or GPH. It indicates how quickly water and debris are pulled through the cleaner. More flow does not automatically mean better cleaning. Once a cleaner has enough flow for the pool and debris load, additional flow can provide diminishing returns while using more battery power. 

Runtime is another figure that needs careful reading. The advertised runtime often refers to floor-only cleaning. Wall and waterline cleaning require more energy because the cleaner has to climb and maintain traction. For that reason, the useful figure is the floor-plus-wall-plus-waterline runtime rather than the headline floor-only number.

Filter mesh is another important specification. Around 180 microns is a common residential baseline. Finer filtration, such as 60–100 microns, can capture more pollen and fine particles but will generally require more frequent rinsing. A dual-layer filtration system combines a coarser outer layer with finer filtration inside.

Basket capacity affects how often you need to stop and empty the cleaner. A 4–4.5 litre basket gives you more room for leaves and debris than a 3–3.5 litre basket, which becomes particularly useful after windy weather or during periods of heavy leaf drop.

Before placing the order

Some of the most important questions are not found in the specification table.

Check the return policy before buying. A cleaner can look ideal on paper and still turn out to be a poor match once it has completed a couple of cycles in a pool with unusual steps, slopes or ledges.

Warranty terms also deserve a proper read. Check whether the battery has the same warranty period as the main unit and which components are considered consumables. Brushes, filters and other wear parts are often treated differently from the main housing.

Finally, check replacement parts. Brushes, tracks, wheels, filters and batteries eventually need replacing. A cheaper cleaner is not necessarily cheaper to own if basic replacement parts are difficult to source.

Common Buying Mistakes in Pool Cleaner

Most buying mistakes come down to choosing a cleaner from one headline specification instead of looking at the pool as a whole.

1. Treating suction as the most important number

A cleaner can have impressive suction and still leave large areas dirty if its navigation is poor. If the robot keeps missing the same sections of the pool, the problem may have more to do with coverage than suction power.

2. Buying an above-ground cleaner for an in-ground pool

An above-ground cleaner is designed around a different pool environment. An in-ground pool may have hard walls, a deep end, steps and a waterline that needs to be cleaned. If the cleaner cannot climb those surfaces, it will never provide full coverage.

3. Expecting it to fix cloudy or green water

A robotic cleaner is not a water-treatment system. Green water is primarily a chemistry problem, while cloudy water can be related to filtration, circulation or water balance. The robot can remove settled particles and dead algae, but it does not replace proper chemical treatment.

4. Ignoring lift-out weight and drainage

A robotic cleaner becomes noticeably heavier when it is full of water. For larger models, easy drainage and a convenient way to bring the cleaner back to the surface can make a big difference to everyday use. Self-docking or waterline parking is particularly useful because it gives you a convenient point from which to retrieve the cleaner.

5. Choosing random navigation for a complicated pool

Random navigation can work perfectly well in a simple pool. It becomes less attractive when the pool has sun shelves, beach entries, multiple groups of steps or a free-form shape.

The cleaner may complete its programmed cycle while still missing sections of the pool. For more complicated layouts, mapping-based navigation is worth considering, with AI vision providing another step up in coverage and obstacle recognition.

How Much Does a Robotic Pool Cleaner Cost?

Robotic pool cleaners cover a wide price range.

Rather than choosing the cheapest model or automatically going for the most expensive one, match the price to the size of your pool, the amount of debris it collects and the features you actually need.

Entry tier

Entry-level cleaners are suited to smaller or simpler pools, above-ground pools and buyers who want to see whether a robotic cleaner fits their routine before spending more. At the lower end, you will generally find floor-only models with shorter runtimes and basic navigation. Move further up the range and wall climbing and waterline cleaning start appearing, although filtration, battery capacity and navigation remain the main differences between models. For a straightforward pool under around 6 × 10 m, an entry-level cleaner can handle routine maintenance well.

Mid tier

The mid-range is where many family pool owners will find the best balance. These cleaners generally offer floor, wall and waterline cleaning, larger baskets, longer runtimes and more advanced navigation. For a typical 6 × 12 m family pool, this level provides the coverage most owners actually need without paying extra for features that may not make a noticeable difference in a straightforward pool. App control is also common towards the upper end of this category.

Upper tier

Higher-end robotic cleaners are aimed at larger pools, complicated layouts and owners who want longer cleaning intervals and more advanced automation.

Features such as AI vision navigation, dual-layer filtration, finer filtration, surface skimming on selected models and runtimes of more than ten hours become more common here.

At this level, the extra spend makes more sense when the pool itself creates a demanding cleaning job.

What else costs money after buying the cleaner?

The cleaner is not necessarily the end of the cost. A storage caddy can make it easier to move and store a heavier unit. A spare basket or finer filter insert can also be useful when there is a particularly heavy debris load and the first basket needs rinsing.

Brushes, tracks and other wear parts eventually need replacing. When comparing models, check whether these parts are readily available in Australia rather than looking only at the initial purchase price.

What Robotic Pool Cleaners Clean

A modern robotic pool cleaner can handle the pool floor, walls and, on suitable models, the waterline.

Depending on the filter and design, it can collect leaves, hair, twigs, sand, gravel, pollen and dead algae that has settled after chemical treatment.

Most robotic cleaners do not remove floating debris from the water surface, and they do not treat an active algae bloom.

The four cleaning modes

Many robotic cleaners offer several cleaning modes, including:

• Floor only

• Wall and waterline only

• Wall and waterline first, followed by the floor

• Full coverage

The right mode depends on what is actually dirty.

After a windy day, a large family gathering or a period of heavy pool use, the waterline may need more attention than the floor.

For normal weekly maintenance, full coverage is usually the most useful option.

If the waterline is clean but the floor is covered in leaves or sediment, a floor-only cycle can save time and battery power.

Surface debris and skimming

Most robotic pool cleaners are designed to clean below the water rather than skim the surface. A small number of higher-end models combine surface skimming with floor cleaning. For most pools, floating leaves remain the job of the skimmer basket, leaf net or pool cover. This can be particularly noticeable in Australian backyards surrounded by mature trees. In those pools, the main problem may be leaves landing on the water before they ever reach the floor.

Algae and dead-algae sediment

A robotic cleaner can collect dead algae once it has settled on the pool floor. It does not kill an active algae bloom. If the pool is green, the algae needs to be treated chemically and the affected surfaces brushed first. Once the algae has been dealt with, the robotic cleaner can remove the dead material that settles on the floor.

Cloudy water and chemistry boundaries

Cloudy water is not necessarily a sign that the pool needs a better cleaner.

Water chemistry, filtration and circulation need to be checked first.

A robotic cleaner can remove settled particles, but it does not adjust pH, increase free chlorine or sanitise the pool.

Choosing an iGarden Robotic Pool Cleaner

The iGarden robotic pool cleaner range covers several different pool sizes and cleaning requirements.

The easiest way to choose between them is to start with the pool rather than the specification sheet.

Pick iGarden K Series for a typical family in-ground pool

Choose K36 if the pool is cleaned regularly and a 3.6-hour floor cycle fits your routine.

Choose K70 for a pool that gets heavier use and needs more runtime for full-coverage cleaning.

Choose K90 for pools that see daily use and need longer cleaning cycles, with up to nine hours of runtime.

All three models share a 4L basket, 180-micron filtration, dual scrubbing brushes and a 15–22 m³/h flow rate.

The full range is available on the iGarden Pool Cleaner K Series.

The Turbo 200% mode is particularly useful after storms, parties or periods when the pool has picked up an unusually heavy debris load.

Pick iGarden K Pro 100 or K Pro 150 for larger pools and longer cycles

Choose iGarden K Pro 100 for pools around 6 × 14 m to 8 × 15 m where a 10-hour floor-mode cycle is sufficient. Choose K Pro 150 if the pool is towards the larger end of that range, cleaning is scheduled over several days, or you want the longest residential runtime in the range, with up to 15 hours of floor cleaning on a single charge.

Both models use the same 14.1Ah 364.2Wh battery, 4L basket, 180-micron filtration and 20–28 m³/h suction flow.

Full specifications and pricing are available on the iGarden Pool Cleaner K Pro product page.

Both models can climb two steps and operate in water as shallow as 35 cm.

Setup, Daily Use and Maintenance

A robotic pool cleaner is relatively simple to operate, but regular maintenance still matters.

The basket should be rinsed after most cycles, the filter mesh should be checked regularly and cordless models need sensible battery care during both the swimming season and the months when the pool is used less.

First-use setup

Before the first cycle, make sure the cleaner's main power switch is turned on.

On most cordless models, this is a physical switch on the unit.

If the cleaner uses an app, pair it before putting the unit in the water. Wi-Fi and Bluetooth signals do not work through water at normal operating distances.

The unit can then be connected using 2.4 GHz Wi-Fi or Bluetooth, depending on the model.

How a cleaning cycle runs

Start by placing the cleaner in the water at the deepest end of the pool and allowing it to sink fully.

Once the air has escaped from the housing, start the cleaning cycle from the app or control panel.

Depending on the model, the cleaner will either finish at the waterline or return to a docking position.

Remove the cleaner, allow excess water to drain, open the basket and rinse the debris away with a tap or garden hose.

Once clean and dry, store the unit somewhere protected.

How often should you run it?

For a residential pool that gets heavy use during summer, two or three full cleaning cycles a week is a reasonable starting point.

During cooler or lower-use periods, once a week may be enough.

After storms, strong winds or a large pool gathering, an additional cycle can deal with the extra debris rather than waiting for the next scheduled clean.

When reopening the pool after the colder months, two full cycles over the first few days can help remove accumulated sediment and debris.

Before closing the pool at the end of the season, one final cleaning cycle is worthwhile before the cover goes on.

Cleaning the filter basket

Rinsing the basket after each cycle is one of the simplest ways to maintain cleaning performance.

As the basket fills, water flow through the cleaner drops. Fine debris is then more likely to remain in the pool even though the cleaner is still moving normally.

The process is straightforward:

1. Remove the basket.

2. Empty the debris.

3. Rinse it thoroughly with a tap or garden hose.

4. Check the filter mesh.

5. Refit the basket securely.

More maintenance advice is available in pool cleaner maintenance.

Battery care and off-season storage

Cordless pool cleaners use lithium batteries, so battery care matters over the longer term. Avoid repeatedly running the battery completely flat where possible. If the pool is used less during winter, store the cleaner with a partial charge, a dry interior and away from freezing conditions. The unit should also be protected from unnecessary prolonged exposure to direct Australian sun.

For a more detailed guide, see how to store a robotic pool cleaner in winter.

Lifespan, Replacement Parts and Warranty

A properly maintained robotic pool cleaner should last for several seasons. How long it actually lasts depends on the pool environment and how it is treated. Three habits make a particularly noticeable difference:

• Rinse the basket after each cycle

• Store the cleaner dry

• Avoid repeatedly deep-discharging the battery

Realistic lifespan expectations

A cleaner running once or twice a week in a well-maintained pool with regular basket cleaning should generally reach its expected service life. A demanding pool environment can accelerate wear. High salt levels, neglected filter cleaning and repeated deep battery discharge can all put additional stress on the cleaner.

Replacement parts to check before buying

Brushes wear out. Tracks and wheels wear out. Filter baskets and finer mesh inserts eventually need replacing. Cordless batteries also lose capacity over time. Before buying, check whether these components are available separately and whether replacement parts can be supplied in Australia. A low purchase price does not mean much if a worn brush or damaged track turns the cleaner into a one-season purchase.

Warranty length and what it covers

Warranty length is useful, but the headline number is not the whole story. A longer full-machine warranty provides a different level of protection from a shorter limited warranty. Read the exclusions carefully. Battery coverage can differ from the main unit on cordless cleaners, while brushes, filters and other wear parts are often excluded as consumables.

Troubleshooting Common Issues

Cleaner not moving or stuck

If the cleaner does not move after starting, check three things first:

1. The power switch is on.

2. The battery has enough charge.

3. The wheels or tracks are not jammed with debris.

Lift the cleaner from the water and inspect the underside, particularly around the drive system.

Weak suction or visible debris left behind

Debris left after a full cycle usually points to one of three things:

• The basket is full

• The filter mesh is clogged

• The cleaning mode does not match the debris pattern

For example, a floor-only cycle will not clean a dirty waterline.

Likewise, a full basket restricts water flow and reduces the cleaner's ability to pick up fine debris.

App or Wi-Fi connection issues

Connection problems are often straightforward.

The most common causes are:

• The home network is running on 5 GHz only

• The cleaner is already underwater

• Wi-Fi signal around the pool is too weak

If the cleaner requires 2.4 GHz Wi-Fi, make sure that band is enabled.

Pair the cleaner while it is still dry and on the pool deck.

If your pool is a long way from the router, check signal strength at the pool before assuming the cleaner itself is faulty.

A broader troubleshooting guide is available at robotic pool cleaner troubleshooting.

App Control and Smart-Home Limits

App control is becoming standard across more robotic pool cleaners.

Depending on the model, an app may allow scheduling, cleaning-mode selection, cycle control and other remote functions.

Native smart-home integration is a different matter.

Most robotic pool cleaner brands, including iGarden, do not currently offer direct Alexa or Google Home voice control. App control through a phone should not be confused with native voice-assistant integration.

Where app control works well is routine scheduling.

You can set recurring cleaning times, select cleaning modes and start a cycle without walking outside to the pool.

AI Timer functions with 24-, 48- and 72-hour options can also reduce the amount of manual scheduling required.

FAQs

What is the difference between robotic, suction and pressure pool cleaners?

A robotic pool cleaner has its own motor, filter and navigation system. It runs independently of the pool's main pump.

A suction-side cleaner connects to the skimmer line and uses the pool pump's suction to move and collect debris.

A pressure-side cleaner connects to the return line and uses water pressure to move around the pool. Some models also require a separate booster pump.

Robotic cleaners are popular because the pool's main pump does not need to be running while the cleaner is operating, and debris is collected in the robot rather than being sent through the pool's main filtration system.

See robotic vs pressure pool cleaners for a detailed comparison.

Does a robotic pool cleaner need the main pool pump running?

No.

A robotic cleaner has its own motor, pump and filter, so it can operate independently of the pool's main circulation system.

Some pool owners prefer to switch the main pump off while the robot is cleaning, particularly when they want the water to remain relatively still while the cleaner maps the pool.

Can a robotic pool cleaner stay in the pool between cycles?

It is generally better to remove the cleaner after each cycle.

Leaving a robotic cleaner sitting in chlorinated or saltwater for extended periods can put additional stress on seals and other components. For cordless models, prolonged exposure can also affect battery life over time.

The safest approach is to remove the cleaner, drain it, rinse it where appropriate and store it somewhere dry and protected.

Do I still need to brush the walls and tiles by hand?

Not necessarily for routine cleaning if your robotic cleaner covers the walls and waterline.

A robot can take over much of the regular brushing that would otherwise be done manually.

However, stubborn calcium deposits, scale and ingrained grout staining may still require manual cleaning.

How long does a robotic pool cleaner take to clean a typical pool?

A typical family in-ground pool may take around two to three hours for a full-coverage cycle, depending on pool size and the selected cleaning mode.

A smaller pool running a floor-only cycle may finish in well under two hours.

Larger pools requiring floor, wall and waterline coverage can take four hours or more.

The important number when comparing cleaners is therefore not simply the advertised maximum runtime, but whether that runtime is long enough to complete the type of cleaning your pool actually needs.

Can a robotic pool cleaner run in a saltwater pool?

Yes, provided the model is rated for saltwater use.

Saltwater pools are common in Australia, but salt can contribute to long-term wear on seals, drive components and external surfaces.

Always check the manufacturer's saltwater compatibility before buying.

What is the return policy if the cleaner does not suit my pool?

Many brands offer a return period from the date of delivery, although the exact terms vary.

Some retailers may apply a restocking fee to a unit that has already been used.

This is particularly important with pools that have unusual shapes, tanning ledges, beach entries or complicated step layouts.

Check the Australian return policy before placing the order. It is worth knowing exactly what happens if the cleaner turns out not to be suitable after its first few cleaning cycles.
