Keeping Plaster Bright
White plaster and marcite are unforgiving: every leaf shadow, tannin spot, and dirt streak shows. Debris that sits overnight — especially leaves and acorns — leaves stains that take acid washing to remove. The fix is frequency: an active-brush robot on a weekly timer removes debris before it can stain.
As one of the largest authorized dealers and retailers of robotic pool cleaners online, we've hand-tested 70+ robots across every major brand — every recommendation below comes from real poolside experience, and every unit we sell is factory-direct with a full manufacturer warranty.
Recommended Cleaners
The Quantum and Premier scrub plaster effectively and include NanoFilters™ to capture the fine particles that cause discoloration. The Cayman is the value pick; the Sigma adds app control for larger plaster pools.
Plaster Care Notes
- Fresh plaster: wait until your builder clears cleaner use (typically after the 28-day cure and startup chemistry) before running any robot.
- Plaster is alkaline and interacts with water balance — mechanical cleaning reduces the chlorine demand that etches plaster over time.
- Algae shadows on plaster respond to the scrub-shock-vacuum workflow in our algae guide.
