Pure Water vs Traditional Window Cleaning: Which Wins in 2026?
The pole-vs-squeegee debate has been going for two decades. Here's what actually matters in 2026 — for the customer, the cleaner, and the business.
Pure-water pole systems have gone from novelty to default for most UK residential rounds. But traditional squeegee work is far from dead — and the best operators use both. Here's the honest breakdown.
What 'pure water' actually means
A water-fed pole (WFP) system pushes deionised water — stripped of minerals via reverse osmosis and DI resin — through a brush head on a carbon-fibre pole. The brush agitates dirt; the pure water rinses it away and dries streak-free without a squeegee.
Where pure water wins
- Reach: comfortable up to 45ft — no ladders needed on 95% of residential jobs.
- Safety: two feet on the ground beats every safety statistic there is.
- Speed on 3-bed+ properties: often 30–40% faster than trad.
- Cleans frames, sills and doors as a by-product.
- Insurance premiums are lower — many insurers now surcharge ladder work.
Where traditional still wins
- Internal cleans — you can't pole an office lobby.
- Very heavily soiled first-cleans — squeegee removes contaminants pure water can leave behind.
- Small terraced streets — setup time can outweigh the clean itself.
- Storefronts and commercial ground-floor glass — squeegee is faster and looks more professional to the passer-by.
The real numbers
A single-van WFP setup — 400L tank, DI vessel, 25ft pole, brush heads — runs £2,800–£4,500 in 2026. RO/DI production at home costs roughly £0.02 per litre. On a typical 4-bed detached that's about 60p of water for a £25 clean. The margin is the pole.
Most cleaners break even on a WFP setup inside 4 months. After that, every ladder-free clean is pure margin — and pure back health.
What customers actually notice
In blind surveys of Squeegify customers, homeowners could not reliably tell WFP and squeegee results apart 24 hours after a clean. What they did notice: whether the frames were clean, whether you turned up on time, and whether the price matched the quote. Focus there.
Our recommendation
If you're starting today, buy the pole first. Add a trad kit for internals and commercial. Price identically — customers pay for a clean window, not a technique.
