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.
The Dolphin Explorer E20 does not include NanoFilters™
The Dolphin Cayman has optional NanoFilters™
Standard Fine Filter
These standard filters help capture larger items such as small leaves and other debris, while maximizing flow rate. However, if your pool struggles with cloudy pool water, small algae, or sand. You many want to consider a unit with NanoFilters™.

Programmable Weekly Timer
An automatic pool cleaner should be automatic, right? With a programmable weekly timer, you can set the robot to clean at different intervals. So your pool robot can clean for you everyday of the week while you sit back and relax - without the need to manually turn it on and off everyday.
The Dolphin Explorer E20 does not include a weekly timer.
