The Raincom difference

Pure-Water Rainwater System

Rain we've collected ourselves, purified on site and fed through telescopic poles. It's the softest, cleanest water you can put on glass.

Raincom rainwater harvesting tank and filtration system

Here's the thing about rain: it starts soft. Much softer than anything from the mains, because it hasn't picked up the minerals that tap water carries. That makes it the perfect base for a chemical-free clean, and it's where the Raincom name comes from.

We harvest rainwater at our depot, then run it through sediment, carbon and de-ionising filters until it's effectively pure H₂O. That water goes up a carbon-fibre telescopic pole to a soft brush head, agitates the dirt off your glass, and rinses clean. Because there's nothing dissolved in it, it dries without leaving a single mark.

No detergents. No additives. Nothing running off into your flowerbeds or down the drain that wasn't already falling from the sky. It's kinder to seals and frames than solvent cleaners, and completely safe for pets, plants and wildlife.
