Buying Guide: What to Look for in a Dolphin Nautilus Waterline Cleaner
Waterline Scrubbing Technology
Not all robotic cleaners scrub the waterline effectively. Look for models that specifically mention waterline scrubbing, which typically involves a rotating brush or dedicated nozzles that target the water’s edge. The Dolphin Nautilus CC Supreme and CC Pro, for example, feature active scrubbing that climbs walls and scrubs the waterline, ensuring no residue is left behind. For pools with heavy sun exposure or frequent use, this feature is essential to prevent buildup.
Pool Size and Coverage
Dolphin Nautilus models are designed for pools up to 33, 40, or 50 feet in length. Choose a cleaner that matches your pool’s dimensions to ensure complete coverage. Larger pools benefit from models like the Nautilus CC Pro or EON 120D, which offer extended runtime and smart navigation to cover floors, walls, waterline, and even steps. For smaller pools, the Nautilus CC or CC Plus are efficient and cost-effective.
Connectivity and Convenience
Modern Dolphin Nautilus models offer Wi-Fi connectivity and app control, allowing you to schedule cleanings and monitor performance from your smartphone. This is a game-changer for busy pool owners. The Nautilus EON 100 and EON 120D are cordless, eliminating cable tangles entirely. If you prefer a corded option, the Nautilus CC Supreme and CC Pro provide reliable performance with app integration. Consider your comfort with technology and the convenience of cordless operation when choosing.

Filtration System
A top-load filter basket makes debris removal quick and easy. All Dolphin Nautilus models feature this design, but some offer finer filtration for capturing ultra-fine particles. The Nautilus Titan and EON 120D include multi-layer filtration, which is ideal for pools with fine debris or those prone to algae. For most pools, the standard top-load filter is sufficient, but if crystal-clear water is a priority, opt for a model with enhanced filtration.
Final Thoughts
After reviewing the top Dolphin Nautilus waterline cleaners, our top recommendations are the Dolphin Nautilus EON 100 Cordless Robotic Pool for its cordless convenience and app control, making it perfect for modern pool owners, and the Dolphin Nautilus CC Supreme Wi-Fi Automatic for its comprehensive scrubbing and included caddy, ideal for those who want a complete solution. Both models excel at waterline cleaning and offer smart features that simplify pool maintenance. Choose based on your preference for cordless operation versus a bundled package with storage.
