A good robotic pool cleaner can save you hours of manual cleaning and keep your pool clear and ready to dive in, without dragging out the vacuum hose every weekend.
But not every robotic pool cleaner suits every pool.
A cleaner that works perfectly in a small plunge pool might struggle in a large family pool. Some robotic pool sweepers are built to handle fine dust and sand, while others are better at chewing through leaves and heavier debris.
Here's what to look for before buying.
Start With Your Pool Environment
This is the first thing you should think about before comparing features or price.
If your pool sits under trees and constantly fills with leaves, bark, gum nuts or twigs, you'll want a robotic pool sweeper with a larger canister system that's quick and easy to empty.
If your biggest issue is fine dust, dirt or sandy sediment settling on the floor, look for a robotic pool cleaner with ultra-fine filtration.
Your pool surface matters too. Concrete and tiled pools often need stronger scrubbing power to help manage calcium build-up and algae, while fibreglass pools are generally a little less demanding.
We service hundreds of pools surrounded by trees in the Illawarra and thanks to our reputation as the "Windy City" these pools often need a very different robotic pool cleaner setup compared to smaller courtyard or plunge pools.
Bag vs Canister Robotic Pool Cleaners
Robotic pool cleaners use either a bag or canister filtration system, and each suits different pool environments.
| Feature | Bag Style Robotic Pool Cleaner | Canister Style Robotic Pool Cleaner |
|---|---|---|
| Ideal For | Fine dust, dirt, pollen and sandy sediment | Leaves, gum nuts, twigs, palm fronds and heavier debris |
| Best Pool Environment | Pools affected by dust or sandy sediment | Pools surrounded by trees or exposed to storms |
| Filtration | Ultra-fine filtration, with some systems filtering down to around 2 microns | Designed to collect larger debris efficiently |
| Maintenance | Takes a little longer to empty and clean | Easy to remove, hose out and re-install |
| Good Choice If... | Your biggest issue is fine debris settling on the pool floor | Your pool regularly collects leaves and larger debris |
Cordless Robotic Pool Cleaner vs Corded
Cordless robotic pool cleaners have become popular over the last few years, especially for plunge pools and smaller backyard pools.
The biggest advantage is convenience. No cords to manage and easy to drop in for a quick clean.
They're a great option for:
- Smaller pools
- Lighter debris loads
- Quick cleaning cycles
- Pool owners wanting a simpler setup
However, battery runtime becomes important in larger pools, and some cordless robotic pool cleaners may need multiple cleaning cycles to finish the job properly.
For larger pools or pools with heavier leaf load, a quality corded robotic pool cleaner is often still the more reliable long-term option.
Do You Need a Wall-Climbing Robotic Pool Cleaner?
Floor-only robotic pool cleaners can work well in smaller pools, but walls, waterlines and steps are where grime, algae and calcium deposits usually start building up.
A robotic in-ground pool cleaner that climbs walls and scrubs waterlines will generally keep your pool looking cleaner between services and reduce how often you need to manually brush.
Most modern robotic pool cleaners can clean:
- Floors
- Walls
- Waterlines
- Steps and ledges
If you have a concrete or tiled pool, wall-climbing capability becomes even more important as these surfaces often need a little more scrubbing power over time.
Regular cleaning also helps prevent algae and debris build-up, which can quickly lead to bigger water quality issues if left unchecked. If your pool water has already started turning cloudy or green, check out our guide on why pools turn green and how to fix it .
The key is choosing a robotic pool cleaner that suits your pool size, surface and the type of debris you deal with most often.
Frequently Asked Questions
Are robotic pool cleaners worth it?
For most pool owners, yes. A quality robotic pool cleaner can save hours of manual cleaning and help improve water clarity by removing debris before it breaks down in the pool. They're especially useful for pools surrounded by trees or exposed to regular dust and debris.
How often should you run a robotic pool cleaner?
Most pools only need a robotic pool cleaner running once or twice a week. If your pool regularly fills with leaves or gets plenty of use, you'll probably want to run it more often during summer or after storms.
What's the best robotic pool cleaner for a concrete pool?
Concrete pools usually benefit from robotic pool cleaners with strong wall-climbing capability and active scrubbing brushes. Because concrete surfaces are rougher than fibreglass, they often require a cleaner with more cleaning power to help manage algae and calcium build-up.
