Dolphin Active 40 Review

What features does it have?

The Dolphin Active 40 is made for pool owners who want stronger coverage and effortless upkeep. It tackles floors and walls automatically, giving you a cleaner pool in 2026 with virtually zero hands-on work.

Wall Climbing

Clean like a pro. With wall coverage, the Dolphin Active 40 can clean and scale your walls with precision and power. While Wall Climbing is a great feature, don't get this confused with the superior waterline cleaning feature.

What is Dolphin Active 40 missing?

Waterline Cleaning

Dolphin Active 40 does not included waterline cleaning. Not only is this an essential feature that you'll want when looking for a pool robot, but one you will likely need. Waterline cleaning enables the robot to climb and reach the dirtest part of your swimming pool. Without this feature, you'll still need to manually clean your waterline by hand with a brush to prevent any algae or scum that builds up. It is one feature that you'll need that is not included with the Dolphin Active 40.

Leaf Bag

With leaves being a common issue, it would be safe to assume most pool robots utilize a leaf bag. Well, no so fast. Nearly every robotic pool cleaner is missing a leaf bag, except the Dolphin Premier. If you have a lot of leaves, this is the best pool robot for leaves. Not to mention the Premier's 3 year warranty, Dual Commercial Motors, and Multi-Media™ make it one of the best models available.

One thing to keep in mind: the Active 40 lacks NanoFilters and ProLine commercial-grade motors. Pool owners who want the sharpest filtration and the strongest clean should look at a ProLine cleaner such as the Dolphin Premier, or a Max-Series model.

What's included with the Dolphin Active 40?

The Dolphin Active 40 includes everything you'll need. Here is what is included with the unit:

• Dolphin Active 40 Unit
• 60 ft Cord with Anti-Tangle Swivel
• Programmable Weekly Timer
• Standard Filters
• 2 Year Warranty

How to set up the Dolphin Active 40

Simply plug and play. All robotic pool cleaners are ready to go right out of the box. No booster pump or assembly needed. The Active 40 has everything needed to get started in its box. It's that easy.
