Frequently asked questions

What surfaces can a window vacuum be used on?
They suit any smooth, sealed surface such as glass, mirrors, tiles and shower screens. They are not designed for textured or porous materials.
Do I still need a cleaning solution?
Yes. A window vacuum removes moisture rather than dirt, so you apply a cleaner first and then vacuum away the liquid for a dry finish.
How long does the battery usually last?
Run time varies by model, but most cover several windows on a single charge. Larger jobs may need a mid-session top up or a spare battery.
