As the weather turns colder, it's no surprise that many of us are grappling with fogged-up windows, smeared glass and stubborn water marks. If you're tired of wiping things down every morning, Amazon's Black Friday deal on the Kärcher window vac WV 2 could be just what you need.

It's now priced at £41.99, down from £79.99 - a substantial 48% saving .

Designed to absorb water rather than dust, the WV 2 makes light work of condensation, window cleaner, soap and shower steam. Consider it as a mini vacuum that guzzles up liquid, leaving glass streak-free with minimal effort.

It's also versatile beyond just windows, as shoppers use it on car windows, shower screens, bathroom tiles, mirrors, kitchen worktops, and patio doors.
