Trust me – you need this miracle product to stop condensation from ruining the windows in your home this winter
Avoid damp, mold and mildew with a window vacuum


In winter, beautiful frosty mornings, cozy fireplaces and twinkling Christmas lights are a given. Unfortunately, though, so too is condensation. But, as an inevitable part of the season, how can you help it?
Condensation not only looks unsightly, it also causes cold, damp patches where mold and mildew thrive. Enter: window vacuums, a genius way to whip away water and leave your windows spotless, streak-free and shining.
As Black Friday sales ramp up, learn how to use a window vac to beat condensation for good, and you will thank yourself later.
This window vacuum set is an easy-to-use complete cleaning system, with a window cleaner concentrate, machine-washable microfiber pad, window vacuum and charging cable. With a battery run time of 25 minutes, you can clean many of your windows without running out of battery or worrying about wires.
If there's one staunch supporter of using a window vacuum, it's one of our editors, Andrea Childs. Living in an old seaside home, she relies on hers each morning to get rid of condensation inside windows – and it's clear to see why.
Designed to spray, wipe, and vacuum windows in a single swipe, window vacuums clean windows without streaks, and prevent mold growth, even when leaving it unheated, by removing excess moisture.
They also offer a convenient solution for cleaning hard-to-reach spots, and are an efficient way to be sustainable at home, too, as they're rechargeable and reusable.
What's more, their cleaning power doesn't stop at windows. They can also be used to clean walls, mirrors, shower doors, tiles, and even car doors.
When paired with one of the best dehumidifiers, such as the 4500 Sq.Ft Most Efficient Energy Star 2024 Dehumidifier available at Amazon (also included in the Black Friday sales) the combination is enough to eliminate condensation for good. As Chiana Dickson, content editor of Solved here at Homes & Gardens says, 'My dehumidifier changed my home and life,' this duo will also make your home smell nice, dry clothes quickly, and reduce allergens – which is why I'll be shopping both this Black Friday.

This is the one product you need to curb condensation
With an ergonomic design, this window vacuum comes with a telescopic pole, for reaching even the hardest, and highest, of corners. It also features an auto-adjust function, to change suction power and pace when moving between surfaces with ease.
This window vacuum has a separate water tank for cleaning and sewage, meaning you won't risk wiping dirty water back over your windows. The compact design can be used one-handed, for tackling showers, windows, mirrors and more.
This window vacuum works effectively with just water, but it can be used with a non-foaming cleaning agent, too. It can work continuously for approximately 24 minutes on a full charge, and features a handy side drain hole for easy emptying without spillages.
Top tips for making the most out of your window vacuum
If you're planning on investing in a window vacuum, these are Andrea's tricks for using a window vacuum successfully:
- Start at the top of the window and work downwards
- Empty the water tank frequently
- Change the angle at which you use the vacuum as you work your way down, to maintain contact with the glass at all times
- Use your window vacuum regularly, even when condensation doesn't seem bad. This will ensure moisture doesn't build-up, even when it's not visible.
be sure to read up on the things we wish we knew about window vacs before buying one to pick the right model for your needs.
