A practical guide to robotic pool cleaners for plaster pools — with honest trade-offs, best-fit picks, and the specs that matter.
Our shortlist focuses on Dolphin models available with authorized-dealer support. The buying criteria below also give you a useful framework for evaluating alternatives from any brand.
Choosing the right robotic pool cleaners for plaster pools comes down to matching the cleaner to your pool, debris, and expectations. We ranked 3 best-fit options and made the trade-offs clear before you compare specifications or price.
Plaster (marcite) is a classic pool finish — relatively smooth when new, but it develops fine texture, staining, and scale as it ages. That texture grabs fine dirt and algae, and plaster shows haze and stains readily, so both scrubbing and fine filtration matter.
A robot with effective brushing keeps plaster from developing a dull film, while NanoFiltration captures the fine particles that would otherwise recirculate and cloud a plaster pool.
Ranked for this specific use case, with the reason each model earned its place—not just a list of specifications.
Our #1 match · Premium
Active brushing keeps plaster from dulling, and NanoFiltration captures the fine particles that cloud plaster pools.
Our #2 match · Premium
Quad brushes clean aged, textured plaster thoroughly; NanoFilters clear the haze.
Our #3 match · Mid-Premium
HyperBrush scrubbing and NanoFilters in a large basket keep plaster bright with low maintenance.
How we ranked them: We matched filtration, brush system, coverage, debris capacity, automation, and warranty to this page's buying need. Pool fit carries more weight than the longest feature list.
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.

Straight answers about choosing robotic pool cleaners for plaster pools.
The Premier or Sigma — effective brushing to keep the plaster bright and NanoFiltration to capture the fine debris plaster texture holds. Both prevent the dull film plaster tends to develop.
Fine dirt trapped in the plaster texture recirculates through coarse filters. A NanoFilter model captures it, restoring brightness.
Brushing helps with surface film and light staining; set-in mineral or organic stains may need treatment. The robot prevents buildup and keeps the surface clean between deep cleans.
