Dolphin Advantage Ultra Robotic Pool Cleaner

The Advantage Ultra is the mid-range Dolphin built around one job: keeping the waterline clean. It maintains grip on the wall throughout the climb, so the tile band gets sustained contact rather than a passing brush.

Waterline first

Maytronics is explicit that constant wall grip is what makes the waterline cleaning work here. A robot that loses traction near the top of the wall gets a fraction of a second on the tile; one that holds position works the band properly.

Surface flexibility

Climbs and scrubs on any pool surface — plaster, pebble, tile, fibreglass, vinyl. That matters more than it sounds, because a lot of cleaners that grip well on plaster slide on smooth fibreglass.

Sizing

Rated for pools up to 43 ft, which covers the large majority of residential in-ground pools. Beyond that, look at the Polaris 9550/9650iQ (60 ft) or a Dolphin from our own range.

Worth knowing before you buy

Review volume on this model is modest and the average is middling. The Dolphin Quantum we stock covers the same pool sizes with a much stronger track record — worth comparing before you decide.
