Which ProLine™ robot is right for you?
The Dolphin Premier is the leaf specialist: its Multi-Media™ system swaps between an oversized leaf bag, standard and ultra-fine cartridges and NanoFilters™, and the 3-hour cycle gives it time to cover a 50 ft pool twice. The Dolphin Sigma adds a gyroscope to the navigation, a third motor and myDolphin™ Plus app control over Wi-Fi, so it is the one to pick for a pool with an unusual shape or a lot of steps. The Dolphin Quantum shares the Max-Series™ platform: dual HyperBrushes, the XXL MaxBin™ with NanoFilters™ in the box and a weekly timer, at the lowest ProLine™ price.
What every ProLine™ model shares
All three climb walls, scrub the waterline, run on a low-voltage power supply with a built-in weekly timer, and carry an anti-tangle swivel on the cable. They are the robots we recommend first for any inground pool over 30 ft, and the open-box and refurbished units below are the same machines with the same support.
