Maytronics Dolphin Premier vs Maytronics Dolphin Nautilus CC Plus

The Dolphin Premier is the stronger cleaner for leaf-heavy pools: it is the only Dolphin with a leaf bag, cleans floor, walls and waterline in a 3-hour cycle, and carries a 3-year warranty. The Nautilus CC Plus adds Wi-Fi control through the MyDolphin Plus app and a top-load cartridge, but it scrubs only floor and walls and its warranty is shorter. Owners of both praise the scrubbing and filtration; the Premier's larger debris capacity and waterline coverage make it the better step up for most in-ground pools.

• Choose the Dolphin Premier if you get leaves and twigs, want waterline cleaning, and prefer a longer warranty over app control.
• Choose the Nautilus CC Plus if you want app control and a top-load filter you can rinse without flipping the robot.
