1. Start with your pool type
This is the biggest factor. Above-ground pools need a lightweight, liner-safe cleaner like the Dolphin Escape. Inground pools benefit from full coverage. Also consider your surface — all quality robots are surface-safe, but rough finishes like gunite wear brushes faster.
2. Size the cleaner to your pool
Match the robot's rated length and cable to your pool. Small pools don't need a flagship; large pools up to 50 ft need strong motors and a long cable.
3. Decide how much coverage you want
Floor-only, floor + walls, or floor + walls + waterline. The waterline holds 90%+ of algae and scum, so for inground pools we strongly recommend full coverage.
4. Prioritize filtration
If you have trees, capacity matters — see cleaners for leaves. For pollen, silt, and dust, NanoFilters capture what standard filters miss.
5. Choose your automation and features
A weekly timer makes a robot truly hands-free. Wi-Fi and app control add scheduling and remote drive. An anti-tangle swivel prevents cord knots.
6. Set your budget
Options range from under $500 to premium flagships. Avoid ultra-cheap generic units that fail within a season — a warrantied budget pick lasts years.
