The top-load filter basket is user-friendly and simplifies debris removal, ensuring clear water with minimal effort. The plug-and-play system adds to its convenience, requiring only a simple setup to start a two-hour cleaning cycle. Weighing 14 pounds, it is relatively easy to handle and maneuver.

This model is corded electric, which means it needs a power source and isn't as flexible as battery-powered options. Additionally, regular maintenance like cleaning the filter and protecting the plastic components from chemicals and extreme temperatures is necessary to ensure longevity. This product is ideal for pool owners looking for a hassle-free, efficient cleaning solution without the need for manual labor, though the corded nature and lack of waterline cleaning may be drawbacks for some users.

Additionally, it is made from plastic and metal, suggesting a robust build, and comes with a 3-year quality assurance for added peace of mind.

It is important to note that the device is corded electric, which might limit its range and flexibility compared to battery-powered alternatives. The need for regular filter cleaning and maintenance could be seen as a drawback for users seeking a low-maintenance solution. The included hose length of 60 feet ensures it can cover the entire pool area effectively, making the Dolphin Premier a strong contender for those looking for a reliable and efficient robotic pool cleaner, particularly for larger in-ground pools.
