What Is Waterline Cleaning?

Waterline cleaning is the removal of buildup from the pool wall at or near the water surface.

Front view of a pool wall with a highlighted band at the water surface. A cleaner straddles the band, with a horizontal movement arrow above it. — Waterline location shown conceptually. The highlighted band is not a measured cleaning width.

Waterline and Water Surface

The waterline is where the water meets the pool wall. Deposits can collect around that boundary. Surface skimming instead collects material floating on the water, so the two functions address different locations.

Aiper Product Context

The Scuba S1 Pro documentation describes horizontal waterline cleaning. Check the selected model and mode: floor cleaning, wall climbing and waterline cleaning are distinct capabilities.

Common Misunderstanding

A wall-climbing cleaner does not necessarily travel sideways along the waterline or clean a specified distance above it. Those behaviors require model-specific support.
