Abstract: A wet cleaning robot includes a body configured to be movable on a surface to be cleaned; a rotational wet pad arranged on a bottom of the body and including a wettable surface configured to contact the surface to wet clean the surface; an electrostatic adsorption pad arranged in front of the rotational wet pad and configured to electrostatically adsorb a foreign substance on the surface under the electrostatic adsorption pad; and a foreign substance barrier wall arranged between the rotational wet pad and the electrostatic adsorption pad to prevent the foreign substance adsorbed on the electrostatic adsorption pad from moving to the rotational wet pad.
