Decision guide
Measure more than pool length. Note benches, tanning ledges, main drains, tight corners and sharp wall transitions because these areas can expose the difference between advertised coverage and repeatable real-pool navigation.
Concrete, vinyl, fiberglass and tile place different traction demands on tracks and brushes. Confirm the exact model-year compatibility, operating depth and salt or chlorine limits before relying on a general in-ground claim.
Still deciding?
Answer five pool-fit questions and see a transparent shortlist.
Common questions
Choose first by surface, longest dimension, floor area and geometry. Large complex pools benefit most from strong navigation and runtime; simple pools may not need premium mapping or surface-skimming features.
Some robots cross or partially clean steps, but full step coverage is rarely guaranteed. Step height, tread depth, buoyancy and the approach angle all affect whether a cleaner can mount and remain on a step.
