This tank-system kit is a professional-grade, portable water-fed glass cleaning setup — ideal for washing windows, curtain walls or large glass surfaces without leaving streaks. It includes a ½-cubic-foot DI tank that purifies tap water through DI resin, supplying “spot-free” pure water for streak-free cleaning. The tank has a built-in handle for easy carrying around job sites. The kit also bundles a water-fed extension pole (the “Bravo” pole) — extendable up to over 22 feet — making it convenient to reach high windows and multi-storey facades. A 150-ft hose reel and pure-water feed line are included, enabling continuous cleaning without frequent refills. Standard hose fittings (¾″ brass garden-hose inlet/outlet) simplify setup by connecting directly to tap water and output line. Because the cleaning water is de-ionized, it reduces mineral spots and leaves glass spotless as it dries naturally. All in all, this kit combines portability, high reach, and purified-water cleaning to deliver a professional, efficient window-cleaning solution.
