The short version

A corded robot runs indefinitely on mains power and generally climbs walls and scrubs the waterline harder. A cordless robot has no cable to tangle and is far easier to drop in and lift out, but is limited by battery life. Buy corded for larger pools and full wall cleaning; buy cordless for convenience and smaller pools.

Choose the Dolphin Nautilus CC Corded Robot if…

Your pool is large, or the waterline and walls are where the dirt actually is. A mains-powered robot can run a long cycle without worrying about charge, and generally puts more energy into climbing and scrubbing.

Choose the AIPER Scuba V3 Cordless Robot if…

You are tired of untangling a cable and want to lift the cleaner out in one motion. For a small or medium pool a single charge usually covers the floor comfortably, and the convenience means it gets used more often.

Frequently Asked Questions

Why do robot cables tangle?

Because the robot turns in one direction more than the other over a long cycle. Swivel cables reduce it considerably, and laying the cable out straight before each run helps more than people expect.

Do robots clean the waterline?

Some do, and it is worth checking the specification, because the waterline is where oils and sunscreen leave a visible band. Not every model climbs that far.

Can I leave a robot in the pool?

No. Remove it after each cycle. Continuous chemical exposure shortens the life of seals and brushes, and a robot left in during shocking will suffer for it.
