Waterfed

Waterfed is a term that can refer to several things, most commonly a method of cleaning windows and other surfaces using purified water delivered through a pole system. This method, often called water-fed pole (WFP) cleaning, uses deionized or reverse osmosis filtered water which, when applied and dried, leaves surfaces spot-free without the need for traditional squeegees or detergents. The purified water's ability to absorb dirt and grime means that once it evaporates, it leaves behind a clean surface. This technique is favored for its safety benefits, as it allows cleaners to work from the ground, eliminating the risks associated with ladders, and its environmental friendliness, as it reduces or eliminates the need for chemicals.

Beyond window cleaning, "waterfed" might also be used in a more general sense to describe any system or process that relies on water as a primary component or delivery mechanism. This could encompass irrigation systems, water-based industrial processes, or even aquatic environments. The specific meaning is usually determined by the context in which the term is used.
