We use advanced water-fed pole systems to safely and effectively clean high and hard-to-reach windows. Our water-fed pole system uses advanced multi-stage filtration to deliver ultra-pure water for a spotless clean. The process runs regular tap water through sediment, carbon, reverse osmosis, and deionization filters — removing minerals and impurities that cause spotting. The result is 100% pure water that naturally attracts dirt and dries crystal clear without any soap or residue.
