Owner reviews
A top-tier pool cleaning robot we recommend without hesitation
In our independent assessment, the Dolphin Sigma earns 88/100 — an excellent pool cleaning robot.
Its strongest area is filtration (94/100), followed by cleaning (88/100). In practice, gyro navigation.
The main caveat is convenience, where it scores 66/100. Specifically, premium price.
At €1700, it's priced around the category average. For most buyers in this category, it's one of the best choices you can make.

Corded or cordless — which is better?
Corded cleaners run as long as you like and never need charging; cordless models are easier to drop in and retrieve with no cable to untangle.
Does it clean walls and the waterline?
Models with waterline scrubbing climb the walls and clean the tile line where oils and scum collect, not just the floor.
Do I still need a separate pool filter?
The robot has its own filter basket/cartridge for debris; it reduces load on your main system but doesn’t replace water chemistry and circulation.
