Clean the traction surfaces
Oils, algae and worn brushes reduce grip. Rinse tracks and rollers, and follow the manufacturer replacement schedule.
Balance the water
Excess algae or unusual water chemistry can make surfaces slippery. Correct the pool condition before judging climbing performance.
Know the geometry limit
Sharp 90-degree transitions, safety ledges and unusual tile lines can interrupt climbing. Compare your pool to the manufacturer's supported shapes and materials.
Your next step
Shortlist the models that fit your pool, then compare exact model-year specifications and current manufacturer terms before ordering.
