Gunite (and shotcrete) pools are finished with a rough, textured surface that grips dirt, algae, and fine grit tightly. Cleaning gunite well takes aggressive scrubbing — suction-only or soft-brush robots skim the surface and leave grime embedded in the texture.
The best robots for gunite pair firm scrubbing brushes with strong suction and fine filtration, so the debris freed from the texture gets captured instead of resettling. Wall climbing keeps the textured walls and waterline clean too.

Most Advanced ProLine
The quad-brush system is the most aggressive scrubber available — it digs grime out of rough gunite texture; NanoFilters capture it.
Flagship ProLine
Commercial motors and active brushing scrub textured gunite hard; ultra-fine media holds the released grit.
Max-Series
Dual HyperBrushes scrub the texture and the XXL MaxBin holds the volume gunite pools shed.
Your pool's interior surface changes which robot cleans best. Delicate liners need gentle tracks and the right brush; hard, textured surfaces like pebble and gunite need aggressive scrubbing to dig grime out of the texture. Matching the robot to your surface protects the finish and gets it genuinely clean.
Textured surfaces (pebble, gunite, exposed aggregate) need firm scrubbing brushes; smooth or delicate surfaces (vinyl, fiberglass) do best with brushes that clean without abrading.
Grip matters on slick fiberglass and smooth tile, while soft rubber tracks or the right wheels protect vinyl liners from wear.
Wall climbing and waterline cleaning keep the tile line and vertical surfaces clean — important on every surface but especially where scale and film build up.
Textured surfaces trap fine grit; NanoFiltration ensures the debris the brushes free is actually captured, not recirculated.

Match the robot to the job
Rough gunite texture traps grit and algae that soft brushes can't reach. You need firm scrubbing, strong suction, and fine capture.
One with aggressive scrubbing brushes — the Sigma (quad brushes) or Premier. Gunite's rough texture traps debris that soft-brush or suction-only robots leave behind.
If it's suction-only or has soft brushes, it can't dig grime out of the rough texture. A firm-scrubbing model with fine filtration releases and captures embedded grit.
Yes — wall-climbing models with waterline cleaning scrub the textured walls and tile line where scale and film collect.
