What features does it have?

The flagship of the commercial Wave lineup. The Dolphin Wave 120 is engineered for the largest, busiest pools, delivering relentless, heavy-duty cleaning with an extra-long reach. In 2026 it's a proven pick for water parks, large resorts, and municipal pools that can't afford downtime. Let's look at what makes it tick.

Waterline Cleaning

The Dolphin Wave 120 has waterline cleaning. This is an essential feature that you'll want when looking for a pool robot. It allows the robot to climb and reach the dirtest part of your swimming pool. Without this feature, you'll likely still need to manually clean your waterline by hand with a brush. It is one feature that you'll need and we're glad it is included with the Dolphin Wave 120.

Wall Climbing

Clean like a pro. With wall coverage, the Dolphin Wave 120 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 Wave 120 missing?

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.

What's included with the Dolphin Wave 120?

The Dolphin Wave 120 includes everything you'll need. Here is what is included with the unit:

Dolphin Wave 120 Unit
130 ft Cord with Anti-Tangle Swivel
Power Supply
Standard Filters
2 Year Warranty

How to set up the Dolphin Wave 120

Simply plug and play. All robotic pool cleaners are ready to go right out of the box. No booster pump or assembly needed. The Wave 120 has everything needed to get started in its box. It's that easy.

As a top-tier commercial machine, the Wave 120 is tuned for endurance rather than residential perks like fine NanoFilters or a home-focused ProLine commercial-grade motor package. For a residential pool that wants that ultra-fine filtration and premium power, consider the Dolphin Premier or a Max-Series cleaner built specifically for the home.
