The device includes a boom and a guide structure pivotally connected to the boom to guide the boom in a forward and a reverse direction along the surface. Preferably, the guide structure is a plurality of skis. The guide structure is covered with mops which contact the surface. The boom is preferably moved in the forward and reverse directions along the surface by a tow line, a plurality of support lines, and a winch. The path of the boom is preferably guided by a pair of pulleys engaging a guide line anchored at the top and bottom of the surface. The method of the present invention includes providing the device of the present invention; rinsing the mops with water, preferably de-ionized water; defining a path along an uncleaned portion of the surface; towing the boom in the forward direction then in the reverse direction across the surface; and repeating the steps until the surface is cleaned.
