The Power of Water®

How the Rainbow® System works.

Most cleaners push fine dust right back into your air. The Rainbow® System does something fundamentally different.

The simple idea

Water traps what bags can't.

Instead of a bag or paper filter, the Rainbow draws air through a basin of plain water. Dust, dirt, dander, and allergens get caught in the water and locked away — so they end up down the drain instead of back in the air you breathe.

That's the meaning behind the Rainbow's two best-known phrases: The Power of Water® and Wet Dust Can't Fly®.

Do the quick math

What do replacement filters really cost?

Most conventional cleaners rely on filters that need regular replacing to keep working right. The Rainbow's main filter is plain water — you just rinse the basin. Drag the sliders and see how it adds up.

You'd keep about $480 in your pocket.
