The Kärcher Window Vac is a quick and convenient way of tackling condensation.
Mel said: “In the mornings in the winter, because we're not double glazed, the water is running down our windows and it's obviously going to damage the paintwork. With this, I can vacuum all of it up. It’s brilliant and it doesn't take very long.”
Mel uses her Kärcher on 11 panes of glass every morning during the winter months. She says that not only does this save time (as well as her paintwork), it also means that she is not going through tea towels at a rate of knots. “I was getting through three or four tea towels each time, wiping the water up and then wringing them out,” she said. “I fill up the reservoir on the Kärcher twice while doing the windows. It's amazing actually how much water you get. "It saves me hours."
And the brilliance of the Kärcher Window Vac is that it doesn’t just work magic on condensated windows, but it can suck up excess water from any flat surface. “It’s also really good for the shower,” agreed Mel. “There is nothing I dislike about it. I love it.”
When you’re done vacuuming, the excess water can be poured straight down the sink, without you having to have any contact with the dirty water. And just like that, the window vac is ready for another round.

Does the Kärcher WV Classic window vac offer value for money?
Mel has been reaping the benefits from her window vac for several years, and says that the vac continues to perform as well now as it did when it was purchased, with no drop in suction. On the basis of this longevity alone, the Kärcher WV Classic offers great value for money, costing less than £50 at the time of writing (September 19th, 2023). It also comes with a spray bottle with microfibre wiping cloth as standard, to help you keep your windows in tip-top shape.
If you like the sound of the Kärcher WV Classic, but are looking for more (or fewer) accessories, then there is a complete universe of Kärcher Window Vacs to choose from, from the basic (but no less efficient) Kärcher WV 1 (£37 on Amazon at the time of writing) to the all-singing, all-dancing Kärcher WV 6 Plus extension set (£139 at the time of writing). In short, there really is a Kärcher Window Vac out there for everyone.
