What to Look for in an Automatic Robotic Pool Cleaner
Wall Climbing Ability
A robotic cleaner that can scale walls and scrub the waterline saves you from manual brushing. Both Dolphin models feature active scrubbing brushes that climb efficiently on any pool surface. The Aiper Scuba S1 also climbs walls, but its Caterpillar Treads system gives it extra traction on textured surfaces. For a deeper comparison of wall climbing performance, see our dolphin nautilus CC plus vs quantum.
Filtration System
Fine debris like sand and dust requires a quality filter. The Dolphin Nautilus CC Plus uses a top-load filter basket that is easy to empty. The Aiper Scuba S1 goes a step further with a dual-layer system: a 3-micron ultra-fine filter paired with a standard 180-micron filter. This captures everything from fine particles to leaves, keeping water visibly cleaner.
Navigation and Coverage
Smart navigation ensures the cleaner covers every inch without missing spots. The Aiper Scuba S1 uses 11 high-precision sensors and a WavePath cleaning pattern for systematic coverage. Dolphin models rely on proven random navigation that still delivers thorough results. If you want app support and scheduled cleaning, the Aiper offers more control. For a side-by-side look at Aiper models, read our Aiper Surfer S1 vs Surfer S2 comparison.
Runtime and Cleaning Modes
Longer runtime means less frequent charging. The Aiper Scuba S1 offers up to 270 minutes in Eco Mode, while Dolphin models run for about 2 hours per cycle. The Aiper also includes Auto, Floor, Wall, and Scheduled modes, plus a weekly cleaning plan. Dolphin units are plug-and-play: just drop them in and let them work.
