A system and method for cleaning tapered towers such wind turbine towers. A semicircular member hugs the tower surface. A plurality of nozzles affixed to the semicircular member sprays high pressure cleaning fluid on the tower surface as the semicircular member is raised and lowered. The spray nozzles are kept at a constant distance from the tower surface by a plurality of wheels affixed to the semicircular member. At least one constricting structure is used to force the plurality of wheels to be in constant contact with the tower surface. The constricting structure can be a spring loaded scissor apparatus and/or a bungee cord with rolling beads. A brush can be optionally added to the semicircular member to aid in cleaning.
