Not all robotic pool cleaners are built the same. These are the machines we'd put in a pool for Plaster Pools — chosen for filtration, coverage, and reliability, and every one is a genuine Dolphin.
The term "robotic pool cleaner" covers everything from bargain floor-only vacuums to commercial-grade machines. When you're shopping for Plaster Pools, the difference between the wrong robot and the right one is filtration, coverage, and build quality — three areas where Dolphin robots by Maytronics consistently lead.
Plaster (marcite) finishes are smooth when new but grow more porous with age, holding onto algae, calcium dust, and fine grime. Keeping plaster bright takes consistent scrubbing and fine filtration.
Plaster benefits from active brushing to prevent algae and dust from bonding to the surface, combined with fine filtration to remove plaster dust and fine debris. Good waterline cleaning keeps the tile-to-plaster line bright, and gentle-but-effective brushes protect aging plaster while still scrubbing it clean.
Because we've tested the full field, these are the specific robots we recommend for Plaster Pools. All are Dolphin models — the brand that keeps winning head-to-head.
HyperBrush scrubbing, waterline cleaning, and NanoFilters keep plaster bright.
Dual brushes and full coverage prevent algae and dust from dulling plaster.
Dual brushes and multi-media filters handle plaster dust and fine grime.

A model with active brushes and fine filtration, like the Quantum or Sigma, because plaster needs regular scrubbing to stay bright and to capture plaster dust.
Plaster sheds fine dust, especially when newer or aging. A NanoFilter robot captures it instead of recirculating it.
Yes. Regular runs with an active-brush robot scrub the surface before algae can bond, keeping plaster clean between chemical treatments.
