NanoFilters™

Often overlooked, having a NanoFilter™ can be the most important part of a pool robot. Without it, small microscopic particulate will pass right through the standard filters found on most robots. These highly advanced filters capture more debris than any other filter on the market, leaving you with a cleaner, happier, and healthier pool.

NanoFilters™ capture fine dirt and debris that passes through the standard filters

Multi-Media™

Struggle with multiple types of debris in your swimming pool? This is your solution. Exclusive only to the Dolphin Premier, MultiMedia® is an innovative solution that allows up to 4 filters options to be changed within seconds. With an included Oversized Leaf Bag, NanoFilter set, and Standard Filter, you can swap between filters to target leaves, microscopic debris, or anything in-between.
