The Dolphin Nautilus CC Plus Wi-Fi Automatic Robotic Pool Vacuum Cleaner is designed for in-ground pools up to 50 feet in length, making it suitable for a wide range of pool sizes. 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 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.

The Dolphin Nautilus Pool Up is a robotic pool cleaner designed for pools up to 26 feet long, suitable for both above and in-ground fiberglass pools. It covers floors and walls effectively, thanks to its wall-scrubbing brush that actively removes dirt without damaging the pool surface. This makes it a good fit if you want thorough cleaning on all pool areas. Its cleaning cycle lasts about 2 hours, which is reasonable for this pool size.

The unit uses a simple plug-and-play system—just drop it in and turn it on—which means it’s easy to use even if you’re not tech-savvy. The robot is self-propelled and equipped with smart navigation to efficiently cover the pool, although it doesn’t specify advanced mapping features like some higher-end models. It runs on AC power with lithium-ion batteries, making it energy efficient for regular use.

The cleaner weighs about 28.5 pounds, which might be a bit heavy to lift but is typical for robots with strong scrubbing power. Some users have noted the weight and occasional difficulty in handling the cord, but its performance and ease of setup tend to balance those minor inconveniences. This model comes with a limited warranty and benefits from Dolphin’s long-standing reputation for durable and reliable pool cleaning products. If you want a straightforward, effective robotic cleaner for a small to medium fiberglass pool without complex setup or controls, the Nautilus Pool Up is a solid choice.
