What features does it have?
The Dolphin Active 20 is a popular mid-range choice for homeowners who want hands-off cleaning without overspending. In 2026 it remains a reliable workhorse, scrubbing your pool floor and walls while you sit back and relax.
Wall Climbing
Clean like a pro. With wall coverage, the Dolphin Active 20 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 20 missing?
Waterline Cleaning
Dolphin Active 20 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 20.
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.
If you're after the absolute best, know that the Active 20 doesn't include NanoFilters or ProLine commercial-grade motors. For top-tier filtration and power, a ProLine cleaner like the Dolphin Premier — or a Max-Series model — is the way to go.
What's included with the Dolphin Active 20?
The Dolphin Active 20 includes everything you'll need. Here is what is included with the unit:
- Dolphin Active 20 Unit
- 60 ft Cord with Anti-Tangle Swivel
- Programmable Weekly Timer
- Standard Filters
- 2 Year Warranty
How to set up the Dolphin Active 20
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 20 has everything needed to get started in its box. It's that easy.
