The HiFlo nLite water poles offer a perfect balance of weight and rigidity and Unger's super light water fed brush makes quick work of even the toughest buildup. This kit is non-powered, DI-only, with no-mess improved Ultra DI resin bags. This kit is perfect for those who are just starting to clean with pure water, use pure water infrequently, work with water with low levels of TDS, and work at low to medium work heights. The kit is ready to use out of the box. Just add a standard garden hose to hook up to a water source and start cleaning.
