To keep dog hair and toddler mess at bay, I use three separate vacuums: a heavy corded one for deep cleaning; a robot vac that I run daily for light maintenance cleaning; and a cordless handheld for quickly picking up small messes. However, it is possible to go overboard. You don't want your descendants to find you buried, a skeletal arm sticking out from under piles of dusty, decaying vacuuming devices. That's where the Coral One comes in.
