mop comes with a twin bucket that has two compartments, one for drying and the other for cleaning. You can clean surfaces using water (and detergent/liquid if any) from one compartment. The mop has to be dried in the other compartment so that the water drips through its perforated surface and the dirt collected does not stick to the mop during the next swipe. The mop has 360 degrees of movement and can clean surfaces with ease.
