A: If you like scheduling, starting, or monitoring cleanings from your phone, the E40’s app control is a major convenience. It’s especially handy for busy families or frequent travelers.
Q: Do I need waterline cleaning?
A: The waterline is where oils and debris collect. If you want a truly spotless pool, the E40’s waterline cleaning is a great upgrade.

Q: Should I get a caddy?
A: A caddy makes it much easier to move, store, and organize your robot and its accessories. It also helps protect your investment.
