The mkro-fiber cleaning pad might be dirty. Flip or change the cleaning pad.
if you washed the cleaning pad with powder detergent then it will damage the pads`cleaning effect and require replacement.

       you might have left the mop in the same spot for too long.
       This might be leftover from past cleaners used on the floor surface.
       Use the Steam Mop a few more times and see if the leftover cloudiness is removed. if this does not work, we suggest rinsing the floor with water, letting it dry. and then steam mopping again with a clean pad. One or more rinses generally removes the residue. A more stubborn case may require you to rinse the floor.
