5-24 ft Water Fed Pole System by EXTEND-A-REACH

This is an all-in-one cleaning system offering up to 30 ft of reach. It combines soap application, scrubbing, and purified rinsing in one flow, reducing tool swaps. The kit includes a 24-foot aluminum telescopic pole, water fed brush, water filter, soap dispenser, squeegee, and upper rinse bar for even water distribution. A 180° angle adapter supports full surface contact on hard-to-reach areas. Best for: homeowners with tall windows or solar panels who want a single setup to cover multiple tasks. Limitation: heavier setup may require more storage space and careful handling on windy days.
XERO Pure

The XERO Pure system emphasizes a three-stage purification process, including carbon, reverse osmosis, and deionization. It’s designed to be durable yet lightweight, aiding mobility on job sites. Filters are straightforward to change, which supports efficient maintenance between jobs. Best for: cleaners who want a reliable purifier with a simple filter replacement routine. Caution: ensure compatibility with your existing hoses and fittings to maximize performance.
Unger Commercial HydroPower Ultra DI Tank

This compact deionization tank removes minerals from tap water, producing pure water for professional, streak-free cleaning. It features FloWater Technology to increase pure water output by up to 30% and improve water distribution. Best for: mobile cleaners and small crews who need a portable, mineral-free solution. Limitation: smaller tank capacity may require more frequent refills during larger jobs.
5-18 ft Water Fed Pole System by EXTEND-A-REACH

This option provides up to 24 ft of reach with a complete 11-piece kit that includes a 18-foot pole, water fed brush, water filter, soap dispenser, and squeegee. It features an integrated upper rinse bar, a 180° adapter for flexible cleaning, and an ergonomic handle. Best for: mid-height windows, solar panels, and sidings where a lighter, more compact system is preferred. Caution: may be less suited for very tall structures without an extension.
XERO Pure Atom

The XERO Pure Atom offers a reliable, user-friendly configuration with three filtration stages and straightforward resin switching when total dissolved solids (TDS) exceed 10 ppm. Best for: users who want a compact purifier with predictable maintenance. Limitation: resin management requires monitoring to sustain peak performance.
Buying Guide
What should you consider when choosing a purified water window cleaning system?
Reach and portability: Measure window heights and whether you require mobile cleaning capabilities. Extends to rooflines and solar panels if needed. Consider how heavy the pole and accessories will be to transport and handle.
Filtration and water purity: Look for multi-stage filtration (carbon, RO, DI) or deionization to ensure mineral-free water. Understand each system’s capacity and replacement needs to plan maintenance.
Ease of use: Favor setups with integrated soap dispensers, rinse bars, and ergonomic handles. An adjustable angle adapter helps you maintain contact with curved or recessed surfaces.
Durability and warranty: Choose stainless or thick aluminum poles for longevity. Consider whether the kit is designed for home use or light commercial tasks, and verify components like hoses and squeegees are robust enough for frequent cleaning.
Safety: Water-fed systems reduce ladder use, improving onsite safety. If you work near electrical lines or on uneven ground, select a system that minimizes final setup complexity and provides stable support.
