Quick verdict
Buy the Pro over the standard S1 if fine dust or pollen haze is your recurring problem — the 3μm filter is the whole point. Otherwise the standard S1 remains the value play.
Ideal for
- Fine dust, sand, and pollen problems
- In-ground pools up to ~2,150 sq ft
- Cordless buyers stepping up from the S1
Not ideal for
- Leaf-heavy pools (fine media clogs faster)
- Surface-debris problems
- Anyone who doesn't need ultra-fine filtration — save with the S1
The full picture
The S1 Pro takes the Scuba S1 formula — cordless floor, wall, and waterline cleaning with about 180 minutes of runtime — and adds the thing dusty pools actually need: a 5L top-load basket running a 180μm fine filter plus a 3μm ultra-fine filter, app control, and infrared obstacle avoidance. Pools that stay hazy after cleaning usually have a filtration problem, not a scrubbing problem, and that ultra-fine media is the fix. For coverage up to about 2,150 sq ft it's one of the cheapest ways to get genuinely fine filtration in a cordless robot.

The in-depth review
The Scuba S1 Pro is the fine-filtration upgrade to our value pick, the Scuba S1. The one reason to pay more is the 3-micron ultra-fine filter — built for pools plagued by dust, silt, and algae haze.
The 3-micron difference
The Pro's whole point is what it catches. Its 5-liter basket takes both a 180μm fine filter and a 3μm ultra-fine one, so the particles that leave your water looking cloudy — fine dust, silt, dead-algae haze — get trapped instead of passing through. You also get full floor, wall, and waterline coverage plus app control with obstacle avoidance.
The trade-offs
Ultra-fine media clogs faster, so you'll rinse it more often, and it's the wrong tool for leaf-heavy pools where that fine filter chokes quickly. There's no surface skimming, and Aiper's support network is still young.
