What traditional window cleaning actually is
“Traditional” means the method you’ve probably seen since childhood: a bucket of water with a splash of professional solution, an applicator (a “T-bar” or hand-held pad), a rubber-bladed squeegee, and a scrim cloth to detail the edges. Upstairs windows are reached by ladder.
A skilled traditional cleaner is genuinely impressive to watch — a single squeegee stroke leaving a stripe of perfectly clear glass. It’s the original professional method and for a long time it was the only one.
The trade-off: every upstairs window means a ladder setup, and every bucket of water is tap water, which leaves mineral deposits as it dries if any drips aren’t squeegeed off perfectly.
What water-fed pole cleaning actually is
Water-fed pole (WFP) uses a telescopic carbon-fibre pole, typically reaching 20–40 feet, with a soft brush and water jets at the head. The water isn’t tap water — it’s run through a three-stage purification system (sediment filter, carbon filter, and reverse-osmosis or deionising resin) until it’s “pure” water with effectively zero dissolved solids.
That pure water is the trick. Normal water wants to bond with minerals as it dries — which is why it leaves spots. Pure water is so “hungry” that it actively lifts dirt off the glass, rinses freely, and dries to a spot-free finish on its own. No squeegee, no scrim, no ladder.
The cleaner brushes each pane, rinses, and moves on. Done correctly, the glass dries clear within minutes.
Head-to-head: what actually matters
| Factor | Water-fed pole | Traditional |
|---|---|---|
| Upper-floor safety | From the ground, no ladder | Ladder every pane |
| Finish on modern glass | Excellent — spot free | Excellent if done well |
| Finish on leaded / stained | Good, occasionally leaves lead lines | Sharper detail |
| Frames & sills | Cleaned as part of every pass | Only if cleaner chooses to |
| Speed on a typical home | 20–30 min | 40–60 min |
| Weather tolerance | Rain is fine | Rain streaks the squeegee line |
| Security | No ladder near your bedroom window | Ladder goes up each visit |
“My windows streaked after a water-fed clean” — what’s happening
I hear this occasionally and there are two usual causes:
- First clean after years of neglect. Years of grime release slowly — sometimes it takes the second monthly visit to lift it all. This is why a first WFP clean is sometimes followed up with traditional detailing.
- Bad water purity. If the cleaner’s filters are past their lifespan, the water isn’t pure and will spot on drying. A good cleaner checks TDS (total dissolved solids) regularly — the target is under 10ppm, ideally 0–5ppm.
Done properly with fresh filters and a reasonable cleaning cadence, WFP leaves glass cleaner than most traditional jobs — because the frames and sills get rinsed too, so drips from frames don’t re-soil the glass after the cleaner leaves.
