After learning that condensation inside windows is bad, as it can lead to significant mold and mildew, Chiana Dickson, content editor on Solved, started using a window vacuum herself each morning.
'I've sworn by my window vac to beat condensation for years,' she says. 'It's the quickest, easiest way to significantly reduce damp, which tends to be a little more prevalent in my home than most, as I live near the coast.
'I like to use mine with my best homemade window cleaner, which is a mix of warm water and Castile soap, available at Amazon, but it's great that this Karcher model comes with a concentrated glass cleaner, too. I've also found that using mine is an excellent way to increase natural light in my home, which is ever more important over these darker winter days and nights.'
Condensation not only looks unsightly – it can also increase damp levels and the prevalence of mold and mildew.
While Chiana's a fan of this great window vacuum, so too are thousands of shoppers, highlighted by the almost 16,000 five-star reviews amassed on Amazon.
'Where has this been all my life?' writes one reviewer, Stephanie. 'Who likes washing the windows? This is a game-changer. Half the time and twice as clean.'
Another, Phoebe, humorously adds, 'My windows are so clean, birds are filing complaints. I didn’t know glass could sparkle this hard. Mixed this magic potion with water, and suddenly my windows looked like portals to another dimension. No streaks, no foggy residue – just chef’s kiss clarity. Bonus: it smells fresh, not like a science lab exploded.
'Paired with my Kärcher WV 6 Electric Window Vacuum available at Amazon, cleaning windows now feels vaguely luxurious. If you’ve ever wanted to see your reflection in a window and question your own existence, this is the cleaner for you.'
A third, C. Barber, echoes that it delivers 'sparkling windows in no time.
'I’m in love with easy window cleaning,' they explain. 'I have kids and pets, and keeping the windows clean was always such a chore, until now. This turns hours-long jobs into minutes, and it’s fun! Indoors and outdoors, it works great,' so you can use it for tackling condensation outside windows, too.
They note the window condensation vacuum is even handy for cleaning other flat surfaces around the home, such as cooktops and counters, which is handy when prepping your home for Thanksgiving guests.
So, avoid condensation and frost on the inside of windows this winter with the Kärcher WV 6 Electric Window Vacuum available at Amazon, now reduced by $39, just in time for December temperatures.
