Scrubbing Power for Textured Gunite
Gunite's rough, porous surface grabs algae and calcium and holds fine debris in its texture. An active scrubbing brush and strong motors are essential to lift buildup — plain suction glides over it. Commercial-grade models handle the abrasion best, since gunite wears brushes and tracks faster than any other surface except pebble.

Best for Gunite
The Premier and Sigma bring commercial motors and aggressive brushing to gunite pools; their drive components are shared with the Dolphin Wave commercial line that cleans gunite hotel pools daily. The Quantum is a strong value option for typical residential gunite.
Gunite Maintenance Notes
- Gunite is the most algae-prone surface — pair the robot with a weekly timer so scrubbing happens before blooms establish.
- Waterline cleaning prevents the calcium-and-scum band gunite pools develop.
- Expect brushes to be a consumable: on gunite, inspect them each season and replace when worn.
Gunite pools are usually finished with plaster or pebble — if yours is, those guides apply too.
