The Black Friday deals are here, and while it’s too late for me – I bought this product last year at full price – the Karcher WV1 window vac is 47% off at Amazon US right now, down from $79.99 to just $42.49. UK shoppers aren’t left out either, as they can grab the Karcher WV2 at a bigger 48% discount, from £84.99 to just £43.99

I live in a flat with not a lot of ventilation, so in the colder weather, lots of condensation collects on my windows and in my bathroom. It got to a point in which mold began to collect on my windowpane, and a few spores got into my rare leather editions of The Lord of the Rings books. I was not a happy camper.

Buying a Karcher WV2 window vacuum was a game changer, as I could wake up in the morning and suck all the moisture from the windowpanes before it became a problem. Likewise, after a hot shower, a quick five minutes with the Karcher WV2 prevents excess condensation. No more mold getting into your bathroom sealant. It’s up there with the best Black Friday dehumidifier deals and Black Friday vacuum deals as some of the top deals on homes kit you’ll find this year.
