They may sound similar but window vacuums aren’t like regular vacuum cleaners – you can’t wave one across your windows and watch the dirt leap in. That’s because window vacs don’t combat dust, but instead suck up water.
These handy gadgets lift excess moisture off windows and collect it in their water tanks. This makes them particularly useful in places prone to condensation and to help combat damp problems, such as black mould and rotting woodwork. They can also suck up the water after you’ve washed your windows or remove moisture from the shower and mirrors in a busy family bathroom.
