Key Differences Explained

1. Cleaning Coverage & Pool Size

• Explorer E20: Cleans floors and walls, ideal for pools up to 33 feet. Perfect for those who want reliable, straightforward cleaning for smaller or mid-sized pools.

• Nautilus CC Supreme: Offers a longer 3-year warranty (extendable up to 6 years), reflecting its premium build and advanced features.
