This integrated rotary system allows the bucket to mop being wrung like a salad spinner. No need to wet your hands !!! and finished splash !!! The level of water mini / max is indicated on the bucket and clips for hanging the broom before dessorer is very well designed. The microfibers are used to clean the floor perfectly. The disc can be easily replaced (it takes 7 to a new disk). I personally have saved time using the broom.
