Choosing a Robotic Pool Cleaner for a Pebblecrete Pool
Pebblecrete is the classic Aussie pool finish, and it's rough on brushes, tracks and wheels. Here's what to look for, and what to ask before you buy.

Pebblecrete, pebble-finish and exposed-aggregate pools are everywhere in Australia, and for good reason: they're durable and look great. But that textured surface is harder on a robot cleaner than smooth fibreglass or vinyl. It wears brushes, tracks and wheels faster, and fine grit settles into the gaps between pebbles.
Our approach. We haven't run long-term tests on pebblecrete ourselves. This guide explains what to check and uses manufacturer spec pages for any figures. Wear rates depend on your finish, water balance and how often you run the robot.
What to check before you buy
1. Does the manufacturer list your surface?
Check the robot's compatible surfaces in the official spec sheet, not just the marketing page.
| Model | Surfaces stated by manufacturer | Source |
|---|---|---|
| Aiper Scuba X1 | Concrete, fibreglass, vinyl, tiles (in-ground) | Aiper AU spec table |
| Dolphin M600 | "A wide range of pool shapes and surface types"; all-terrain PVC brushes | Maytronics AU / M600 brochure |
| Zodiac Alpha iQ RA 6700 iQ | "All floors and surfaces", in-ground and above-ground with rigid walls | Zodiac RA 6700 iQ leaflet |
| Beatbot AquaSense 2 Pro | Above-ground and in-ground; all shapes. Surface list not stated on the pages we checked, so ask Beatbot | Beatbot |
| Wybot C2 Vision | Above-ground and in-ground; all pool shapes. Surface list not stated on the page we checked, so ask Wybot | Wybot AU |
Pebblecrete is a concrete pool finish, so "concrete" compatibility is the line to look for. If in doubt, email the brand and keep the reply. It helps if you ever need to make a warranty claim.
2. Brushes and drive: how quickly do they wear, and can you get spares?
On a rough finish, brushes, tracks and wheels are wear parts. Before you buy, check:
- whether the brand sells replacement brushes, tracks or tyres in Australia
- whether the warranty treats them as consumables (most do)
- whether there's a brush option recommended for pebble finishes.
3. Waterline tiles
Many Aussie pebblecrete pools have a tiled waterline band, and that's where scum and sunscreen build up. Waterline cleaning is listed for all five models above. Zodiac's RA 6700 iQ and Dolphin's M600 both list a dedicated waterline mode. The Aiper Scuba X1 lists horizontal waterline cleaning.
4. Fine grit and dust
Pebble finishes trap fine grit in the gaps between stones. Multi-stage filtration helps with this: for example, Aiper lists a 3 µm MicroMesh insert, Wybot a 10 µm ultra-fine filter, and Zodiac a 60 µm canister with very-fine filter options. Remember that fine filters clog faster if there are also leaves. See our gum-leaf guide.
5. Wall climbing
Texture often helps grip, but a full filter or worn tracks will stop any robot from climbing properly. Zodiac lists a pressure sensor on the RA 6700 iQ for wall climbing and waterline cleaning. Maytronics lists its PowerStream mobility system on the M600.
Keep the pebblecrete itself in good shape
Your water balance matters as much as the robot. Water that's out of balance can etch or scale a pebble finish. SA Health recommends keeping pH between 7.2 and 7.6 for home pools. Test regularly and correct promptly. If you're adding chlorine or salt, use our calculator to work out doses, and follow the product labels.
- Brush the walls and steps by hand now and then. Robots don't reach everything, especially step corners.
- Clean the robot's filter after every run so suction stays strong.
- Inspect the brushes and tracks every few months, and replace them before they wear smooth.
- Get leaves out quickly to prevent tannin stains on lighter pebble colours.
Deciding between battery and cable? Read cordless vs corded.

Can a robotic pool cleaner be used on pebblecrete?
Generally yes. Pebblecrete is a concrete pool finish, and most robots list concrete pools as compatible. Check the manufacturer's surface list for your exact model, and expect brushes, tracks and wheels to wear faster than they would on fibreglass or vinyl.
What brush type is best for pebblecrete?
Follow the manufacturer's recommendation for your surface. Some ranges offer different brushes for different surfaces. Maytronics, for example, describes the Dolphin M600's brushes as all-terrain PVC brushes. Ask the seller which brush suits a pebble finish, and whether spares are stocked in Australia.
Why does my robot struggle on the walls of my pebblecrete pool?
The usual culprits are worn brushes or tracks, a full or clogged filter reducing suction, or an incorrect wall-climbing setting. Clean the filter first, then check the brushes for wear against the manual.
