In addition to its ergonomic advantages, water-fed poles have helped to eliminate the streaks on glass that are often associated with the use of unfiltered water and detergents. Today’s water-fed poles use a reverse osmosis deionization (RO/DI) filtration system to purify water.

“In the past 15 years the advent of pure water has dramatically changed the use of water-fed poles,” says Evans. “When using tap water, people noticed occasional streaking or spotting on the glass. The benefit of using pure water is we eliminated about 99 percent of streaking on the glass, and in many cases pure water eliminates the soap requirement, as well.”

By skipping the step of applying and rinsing off soap, window washers are also able to work more quickly, which translates into labor savings, as well as environmental benefits.

“You no longer have detergent leaking down into flowerbeds and onto shrubs,” says Condie.

Furthermore, purified water makes water-fed poles effective tools for cleaning exterior surfaces beyond windows, such as painted metal or stone.

“These tools only go up to about five stories, but the majority of buildings we service in the United States are not high-rise buildings,” says Condie. “If you look at the safety factor and the number of buildings that are three to five stories, you’ve taken a huge chunk of the window cleaning market and made it very safe to service these facilities.”
