The X10 Pro Omni features dual oscillating brushes that do an excellent job mopping floors, even scrubbing away dried stains during our tests. Its square (I suppose it's more of a squircle) shape makes it easier to clean into corners compared to rounder models, while its separate all-in-one dock handles auto-emptying, washing, and refilling - with the heated mop conveniently helping to keep the base clean so it doesn't get smelly.
