The Dolphin Nautilus CC Plus is a fully automatic robotic pool cleaner specifically engineered for in-ground pools up to 40 feet in length. It is best suited for pool owners who want a hands free cleaning solution that handles both floors and walls with minimal intervention.
Standout features include its active scrubbing brush which combines wall climbing power with a continuous scrub action. This means it loosens and removes stubborn dirt, algae, and debris from pool surfaces without the need for manual brushing. The top load filter basket is another highlight, allowing quick removal of captured debris for consistently clear water.
In real world performance, the plug and play design truly simplifies pool maintenance. Simply connect the power supply, drop the unit into the water, and let it run for about two hours. Its smart navigation ensures thorough coverage even around obstacles and irregular shapes. The build quality reflects Dolphin's40 plus year legacy in pool care, using durable materials to withstand constant submersion and chemical exposure.
One potential drawback is its limitation to in ground pools only, so owners of above ground pools will need a different model. Also, there is no manual remote control, but the autonomous navigation is generally effective. At just over20 pounds, it is easy to lift but may be heavy for some users. Overall, the NautilusCC Plus offers exceptional value for those seeking a reliable, low maintenance robotic cleaner.Final verdict: For in ground pool owners who value convenience and thorough cleaning, the Dolphin Nautilus CC Plus is a top choice. Its wall climbing scrubbing action, easy filter access, and set and forget operation make it a worthwhile investment that saves time and effort.

Buying Guide: What to Look for in Pool Robot Brushes for Better Scrubbing
Bristle Material and Stiffness
The bristle type determines how effectively the brush removes algae and debris without damaging your pool surface. Nylon bristles, like those on the Sepetrel 17.5-Inch Hemispherical Pool Brush Head, are gentle on vinyl liners yet tough on dirt. Stainless steel bristles, such as those on the Poolmaster 5-Inch Stainless Steel Pool Algae Brush, offer aggressive scrubbing for concrete or gunite pools but must never be used on soft surfaces.
Brush Head Size and Shape
Wider brush heads, like the TidyMister 20″ 2 in 1 Pool Brush Head, cover more area per stroke, saving time and effort. Curved or hemispherical shapes, such as the Sepetrel Curved Pro and the HydraJoy curved-end brush, reach corners and steps without damaging liners. For robotic units, the Dolphin Nautilus CC Plus uses an active scrubbing brush that climbs walls and scrubs uniformly.
Compatibility with Pool Surfaces
Always match the brush to your pool material. Vinyl liners require soft nylon or synthetic bristles to avoid tears. Concrete and gunite pools can handle tougher stainless steel or polypropylene bristles. The ATIE Cyclonic Scrubbing Brush is designed for Zodiac robotic cleaners and works best on hard surfaces. Check your pool type before purchasing.
Ergonomic Design and Pole Compatibility
An ergonomic brush reduces fatigue during long cleaning sessions. Look for angled handles (45 degrees), lightweight aluminum construction, and clip systems that protect fingers when attaching poles. The Sepetrel Rotatable Brush and the U.S. Pool Supply hand-held options offer versatility for tight areas. For robotic units, plug-and-play operation like the Dolphin’s eliminates manual effort.

Final Thoughts
For most homeowners, a combination of a quality manual brush and a robotic scrubber delivers the best results. The Sepetrel 17.5-Inch Hemispherical Pool Brush Head excels at reaching every corner with its hemispherical bristles and lightweight aluminum build, perfect for routine manual scrubbing. If you prefer a hands-free solution, the Dolphin Automatic Robotic Pool Vacuum Cleaner provides active scrubbing that climbs walls and lifts debris, leaving your pool pristine with minimal effort. Whichever you choose, investing in the right brushing tools transforms pool maintenance from a chore into a quick, satisfying task.
Frequently Asked Questions
What type of brush is best for algae removal in a concrete pool?
For concrete or gunite pools, stainless steel bristle brushes like the Poolmaster 5-Inch Stainless Steel Pool Algae Brush provide aggressive scrubbing that breaks up stubborn algae. Always avoid using them on vinyl or fiberglass surfaces.
Can I use a stainless steel brush on a vinyl liner pool?
No, stainless steel can tear or scratch vinyl liners. Use a brush with nylon or synthetic bristles, such as the Sepetrel 17.5-Inch Curved Pro Pool Brush Head or the HydraJoy Pool Brush Head, which are safe for all pool surfaces.
How often should I replace my pool robot brush?
Replace manual brush heads every season or when bristles show signs of wear, typically every 1 to 2 years. For robotic cleaners like the Dolphin Nautilus CC Plus, check the scrubbing brushes every six months and replace if broken or flattened.
Do robotic pool cleaners have replaceable scrubbing brushes?
Yes, many robotic cleaners such as the Dolphin and Zodiac models come with replaceable scrubbing brushes. The ATIE Cyclonic Scrubbing Brush is a popular replacement for Zodiac MX8 Elite and MX6 Elite models.
