The formula is acid-free, which means it is safe for delicate surfaces but will not remove calcium deposits or hard water stains. For those issues, an acid-based cleaner is recommended. The product is also not intended for painted or ink printed surfaces, such as printed vinyl liners or decals, so always test in an inconspicuous area first.
Build quality is solid with a 32 oz spray bottle that delivers adequate coverage for most residential pools. The instructions are clear, and the included sponge adds value. However, the limitation on printed surfaces and the inability to handle hard water buildup are honest drawbacks to consider.

Buying Guide: What to Look for in a Dolphin Pool Cleaner for Waterline
Waterline Scrubbing Technology
Not all robotic cleaners can reach the waterline. Look for models with dedicated waterline scrubber brushes or wall-climbing capability that lets the robot scrub the tile line as it moves. Dolphin’s active scrubbing brushes are gentle on surfaces yet tough on grime, ensuring a thorough clean without scratching. Models like the Dolphin Proteus DX5i Wi-Fi Automatic Robotic Pool and the Dolphin Explorer E40 Automatic Robotic Pool Vacuum feature specialized waterline scrubbing.
Some models also include sun-ledge cleaning, which is great for shallow areas where waterline buildup often starts. If your pool has a sun ledge or steps, prioritize a model with that capability.
Connectivity and Convenience
Wi-Fi enabled models allow you to schedule cleanings from anywhere via a smartphone app. This is especially handy for maintaining the waterline regularly without having to remember to start the robot. The Dolphin Proteus DX5i and Dolphin Nautilus CC Pro Wi-Fi Automatic Robotic both offer app control. If you prefer a cordless option, the Niya Sonar 60 Cordless Robotic Vacuum Pool Cleaner (from the creators of Dolphin) provides up to 5 hours of runtime and app scheduling.
For deeper pools or larger pools, consider models with longer cables or cordless designs. Our guide to deep pool cleaners can help you choose.
Filter and Maintenance Ease
A top-load filter basket makes cleaning the filter a breeze—simply lift it out and rinse. This is a standard feature across most Dolphin models and saves you from flipping the robot over. Look for fine-mesh filters (like the 120-micron basket on the Niya Sonar 60) if you have fine debris like sand or pollen. Regular filter cleaning ensures the waterline scrubber gets enough water flow to work effectively.
Pool Size Compatibility
Dolphin cleaners are designed for specific pool lengths. Make sure the model you choose matches your pool’s size. For pools up to 33 feet, the Dolphin Nautilus CC Automatic Robotic Pool Vacuum is a solid choice. For larger pools up to 50 feet, the Dolphin Nautilus CC Supreme Wi-Fi Automatic offers extended coverage. Always check the maximum pool length in the specifications.
If you have an above-ground pool, some Dolphin models work well too. See our best above-ground pool cleaner for leaves for more options.
Final Thoughts
For the best waterline cleaning performance, we recommend the Dolphin Proteus DX5i Wi-Fi Automatic Robotic Pool for its dedicated waterline scrubber, Wi-Fi scheduling, and reliable wall-climbing action. If you prefer a more budget-friendly option without sacrificing waterline scrubbing, the Dolphin Automatic Robotic Pool Vacuum Cleaner (Nautilus CC Plus) delivers excellent results with active scrubbing and easy filter care. For manual spot treatments, the STAR BRITE Home Pool Waterline Cleaner Scum is a quick fix for stubborn rings between robotic cleanings.

Frequently Asked Questions
How does a robotic pool cleaner clean the waterline?
Robotic pool cleaners with waterline scrubbing capability climb the pool walls and use specialized brushes to scrub the tile line at the water’s surface. The robot’s movement and water flow help dislodge oils, dirt, and scum, which are then filtered out. Models like the Dolphin Proteus DX5i are designed to grip the wall and constantly scrub the waterline during their cycle.
Do Dolphin pool cleaners work on all pool surfaces?
Yes, Dolphin robotic cleaners are safe for vinyl, fiberglass, plaster, and tile surfaces. Their active scrubbing brushes are gentle yet effective. However, for painted or printed surfaces (like some vinyl liners), always check the manufacturer’s recommendations. The STAR BRITE cleaner has specific warnings for printed surfaces.
Can I use a waterline cleaner with my existing Dolphin robot?
If your Dolphin robot does not have a dedicated waterline scrubber, you can supplement with a manual cleaner like the STAR BRITE Home Pool Waterline Cleaner. Apply it, let it soak for 30 seconds, and wipe away. This is ideal for quick touch-ups between robotic cycles.
How often should I clean the waterline?
For best results, run your robotic cleaner daily or every other day during peak swimming season. If you notice a ring forming, use a manual cleaner immediately. Regular maintenance prevents buildup and keeps your pool looking inviting all year.
