WFP stands for water-fed pole: a telescopic pole that pumps purified water up to a jetted brush head, so you scrub and rinse windows from the ground. Because the water is filtered below 10 ppm TDS, the glass dries spot-free with no detergent, no ladder and no squeegee.
How water-fed pole cleaning works
A WFP system has four parts. The pole telescopes from 2 m up to 9 m and beyond. The brush head carries soft bristles and two or more water jets. A hose runs up the pole from a pump. A filtration stage (DI resin, RO membrane, or both) purifies tap water before it reaches the glass.
The method is scrub, rinse, walk away. Bristles loosen dirt while the jets flush it off the pane. The final rinse is left to dry on the glass. Pure water contains no dissolved minerals, so it evaporates without leaving the white spots tap water causes.
What WFP cleaning replaces
One operator with a 9 m pole cleans triple-storey glass from the ground. That removes ladders, scaffolds and rope access for most buildings, and with them the biggest safety risk in window cleaning. It removes detergent too — the purity of the water does the finishing work a squeegee normally does.
| Traditional | Water-fed pole |
|---|---|
| Ladder or lift for height | Ground-level reach to ~9 m |
| Soap + squeegee finish | Pure-water rinse, air dry |
| Detergent residue attracts dirt | Nothing left on the glass |
| Slow on frames and sills | Brush cleans frames in the same pass |
What the letters hide: the water matters more than the pole
The pole is reach; the water is the result. Tap water in South Africa typically measures 50–300 ppm of dissolved minerals. Spot-free drying needs a reading below 10 ppm. Every WFP setup therefore includes filtration — the choice between resin and membranes is covered in RO vs DI for window cleaning, and the purity numbers in total dissolved solids (TDS).
Who uses WFP systems
Professional window cleaners use WFP for speed and height access. Building maintenance teams use it for regular contract work. Homeowners with double-storey glass use entry-level kits to stop paying for a service they can do from the lawn. Solar panel cleaning uses the same pure-water principle with a rotating brush — see the rotating solar brush machines guide.
Getting into WFP cleaning
A complete starter setup — pole, brush, hose and filtration — is in the 6 m waterfed pole kit (R12,990) for double-storey work, or the 9 m waterfed pole kit (R14,860) for triple-storey. Poles and parts are under waterfed pole systems; the full buying logic is in the waterfed pole equipment guide.
