It excels in cleaning coverage, efficiently scrubbing walls and navigating various pool shapes and surfaces, including fiberglass. The convenience of Wi-Fi connectivity allows you to schedule cleaning cycles from anywhere, ensuring your pool stays clean without constant manual intervention.

This model also comes with a Universal Caddy that provides easy storage and transport, with a tangle-free cable holder to keep things organized. The filter system is user-friendly with a top-load filter basket that simplifies debris removal, making maintenance straightforward. Additionally, the Dolphin Nautilus CC Plus is recognized for its durability over many years of use, offering significant cost savings and high energy efficiency.

On the downside, the product's weight of 768 pounds is considerably high, which might make handling and installation challenging for some users. The price point could be a consideration as it ranks high among robotic pool cleaners. Despite these drawbacks, this cleaner is a solid choice for anyone seeking a reliable, efficient, and easy-to-use robotic cleaner for their fiberglass pool.

The Aiper Scuba S1 robotic pool cleaner is a strong choice for fiberglass pools, offering thorough cleaning with its double filtration system. It uses two filters—a fine 3-micron one and a standard 180-micron filter—that help capture both tiny particles and larger debris, improving water clarity effectively. Its smart WavePath 2.0 navigation ensures the cleaner moves methodically across your pool surface, including walls and waterlines, so you don’t miss spots.

The 180-minute battery life is notably long, making it suitable for larger pools without needing frequent breaks to recharge. This means more uninterrupted cleaning time compared to many competitors. The cleaner is battery powered, so there’s no need for cords, which adds convenience and safety. Controlling the device is easy via a dedicated smartphone app, which also allows for over-the-air updates to keep the cleaner improving over time. Maintenance is straightforward since the filters are replaceable and designed to be user-friendly.

While the product is energy efficient thanks to its battery operation, it may not be the fastest cleaner if you are in a hurry, as the cycle focuses on thoroughness over speed. Also, the app control is handy but might require some initial setup for less tech-savvy users. Its size is moderate and suitable for most fiberglass pools but double-check your pool dimensions. With a 2-year warranty and strong customer ratings, it provides confidence in durability and performance. This cleaner suits pool owners who want a reliable, hands-off cleaning experience with good coverage and fine debris removal.

The Dolphin Nautilus CC robotic pool cleaner is a solid choice for fiberglass in-ground pools up to 33 feet long. It stands out with its ability to climb walls and scrub surfaces actively, which helps keep your pool thoroughly clean without you needing to intervene. The top-load filter basket is easy to remove and clean, making maintenance straightforward and helping ensure clear water.

It runs on a lithium-ion battery, which offers good energy efficiency, and the included caddy makes carrying and storing the unit hassle-free. Its compact design and app control add to the convenience, especially for users wanting a simple, plug-and-play experience. However, while it covers standard pool sizes well, it may not be the fastest cleaner available, and its 40-pound weight can be a little heavy for some to lift. Also, it doesn't have advanced mapping technology, so navigation is efficient but not highly precise.

If you want a dependable, easy-to-use robotic cleaner that handles typical debris and keeps a fiberglass pool spotless with minimal effort, the Dolphin Nautilus CC fits the bill well.
