Independent rankings
Robot vacuums that mop with a rotating roller rather than pads, ranked on mopping, on the dock's washing and drying, and on cleaning.
A roller mop presses a rotating cylinder onto the floor and wrings it inside the machine as it goes, so the water that touches the floor is clean water, where a pad drags the same cloth across the room. Only machines with a roller are here; weighted heaviest on mopping and on what the dock does to the roller afterwards, because a roller that is washed and dried in the dock is the whole point of the design.
