Infinity (vanishing-edge) pools look dramatic, and a good robot keeps the main basin just as clean as any other pool.
The Main Pool Cleans Normally
The large body of an infinity pool — floor, walls, and the normal waterline on the non-vanishing sides — is well within the wheelhouse of a quality robot. Strong climbing and smart navigation give you full coverage, exactly as in a conventional pool.
The Vanishing Edge and Catch Basin
The infinity edge works by water spilling over into a lower catch basin. That overflow trough and basin are typically handled by the pool's circulation and filtration system, plus occasional manual cleaning — they are not where a robot operates. The robot focuses on the main pool, which is the vast majority of the surface area.
Getting the Best Results
Because infinity pools are often larger and premium, pair them with a premium cleaner. A model with gyroscopic mapping and NanoFilters, like the Dolphin Sigma, delivers complete, efficient coverage and crystal-clear water. If your pool is on the larger side, prioritize cord length and cycle coverage — see our best robotic pool cleaners guide and how to avoid missing spots.
