Maytronics Dolphin Premier vs Maytronics Dolphin Nautilus CC Supreme

Both are Maytronics corded robots for in-ground pools up to 50 feet, cleaning floor, walls and waterline. The Premier is the leaf-heavy yard's pick: its leaf bag holds bulky debris that clogs cartridges, and it runs a fixed 3-hour cycle with a weekly timer. The Nautilus CC Supreme adds app control, selectable cleaning modes and an ultra-fine filter kit, so it suits fine silt and owners who want to steer the clean. Owners of both praise the scrubbing and coverage; the Premier's knock is the lack of app or remote, the Supreme's is cartridge cleaning after every run.

• Choose the Dolphin Premier if your pool collects leaves and twigs and you want a big leaf bag plus a simple one-button clean.
• Choose the Dolphin Nautilus CC Supreme if you want app control, adjustable cycles and an ultra-fine filter for silt and sand.
