I’ve found the best window vacuums to banish condensation and damp for good

The Beldray BEL0749 Cordless Rechargeable Window Vacuum is the cheapest vac on our list, and we think it’s a great affordable option with some solid cleaning capabilities. It might not give you the perfect glow that the Kärcher’s WV 6 plus delivers, but reviewers are still super pleased with the results. 

“Gone are the days of shower screens that look all blotchy and smeared with watermarks... and my patio doors now sparkle... Super, super easy to use and the battery life is brilliant! I'd defo recommend this,” said one. 

It offers 30 minutes of usage before it needs charging, removes grime and leaves windows streak-free, plus emptying the 60ml tank is easy – just pour the dirty water out and you're ready to put it away until the next time.

The Kärcher WV 6 Plus N Window Vac is one of the finest window cleaners available right now, with all the additional perks you could possibly wish for. Our reviews editor, Emily Gilbert, absolutely loves it, saying “"I've never owned a window vac before, but I have been SO impressed with the Kärcher WV 6 Plus N.”

This vacuum has so much going for it, including a 100-minute battery life, which is a good amount of time before needing a charge. Emily also said, “I like the LED battery indicator that tells me at a glance how long I have left.”

Of course, what we really want to know is: how well does it clean windows? Well, Kärcher’s window vac does not disappoint. Its excellent suction leaves windows bone-dry, so there’s no chance of bothersome streaking, which is precisely what you pay for.

While this is undoubtedly a really good window vac, it’s not flawless. “The instructions were somewhat limited, but it's pretty easy to figure out yourself as it's just so straightforward to use,” Emily said. “Also, the addition of the spray bottle with a microfibre cloth is great, but I do wish you got more than 20ml of window cleaning concentrate included."

Overall, Emily summed the Kärcher WV 6 Plus N Window Vac up as follows: “Easy and effective, it delivers results instantly and is nice and lightweight to hold.”

The Bosch Cordless Window Vac GlassVAC is a great alternative to Kärcher’s window vac monopoly, with reviewers highlighting the advantage of having 2 different blade options: “Having Georgian type windows, the option of two wiper blade widths is really well thought out. I’m now also using it for other things I’d never thought of before such as cleaning/vacuuming my shower screen and bathroom tiles. Would highly recommend!”

The Bosch GlassVac is practically half the price of the Kärcher WV 6, but still comes with added extras such as a microfibre cloth attachment and the aforementioned different wipers. It’s a great affordable option and does a fab job at removing smears. We also love that it’s lightweight, making it easier for those who may have any form of arm or shoulder impingement.

There’s no need to balance on a footstool to reach high windows with the Leifheit Dry & Clean Window Vacuum Cleaner Set, because it comes with an attachable 43cm-long handle. The vacuum has been designed for 360° use so you can vacuum above your head and at an angle to help you reach even the most difficult spots. 

Reviewers noted the quality of the product and also the speed of the vacuum at removing moisture: “A well-made brilliant piece of kit, just wish I had found it sooner as my curtains on my large bay windows are ruined with condensation. It removes condensation in about three minutes.”

One feature that we think is great is its automatic standby mode. This means it only uses power when in contact with the window so you’re not only saving energy but get about 35 minutes of full use before it needs recharging.

This Kärcher Window Vac WV 2 Plus N comes with a 35-minute battery running time, AN LED display that shows your battery status, 2 suction nozzles, a spray bottle with a microfibre cloth and a 20 ml window cleaner for ease and efficiency. The WV 2 is particularly light, very quiet and easy to use. Plus, it ensures that windows are thoroughly cleaned without leaving any drops and streaks behind. Window cleaning will become an effortless task, we're sure...

With over 8,000 ratings, this Karcher Window Vac is a popular pick, garnering a 4.5/5 average star rating. It's loved by users for its lightweight feel and ease of use - making the chore of cleaning so effortless. Plus, it's effective on multiple surfaces - from shower screens to tiles to kitchen work-tops - as well as windows. Customers love that this pick, when used correctly, leaves glass surfaces clean and smear-free. Quick and efficient, it removes condensation, dries surfaces quickly and reduces so much effort.

However, there are mixed reports on the battery - though good, some users have concerns about the charging time. Further, some users would have preferred a digital display for better tracking. Plus, the on-switch can be stiff - which may not suit all.

Ideal for use on indoor and outdoor windows as well as mirrors, showers and tiles, the Tower T131000BLG RWV20 Cordless Window Cleaner provides an all-around clean for the home. 

There are so many extra features – it comes with a microfibre cloth, squeegee and 300ml solution spray bottle to give 3-in-1 window cleaning, you just have to spray the surface with detergent, clean with the cloth and vacuum the dirty water away to remove the dirt and grime. 

One reviewer commented that they bought it with the aim of reducing condensation in the house, and it’s been working really well. It provides a 30-minute runtime from a rapid three-hour charge so you can clean a range of surfaces in one go and if you’re anything like us, you can charge it and go back to the bits you forgot later!

The Beldray Cordless Window Vac is super stylish, but more importantly, it is so lightweight and easy to hold. It takes 2-3 hours to charge, and that gives about 30 minutes of operating time. It also comes with a squeegee head for removing excess water, which is especially helpful for shower screens. 

It does a good job of delivering a streak-free shine to windows, but it’s not without its faults. One reviewer noted, “I had to keep the vacuum upright to avoid the collected water leaking." However, they still felt the Beldray cleaned well, although it took a few minutes to figure out how the water tank worked and how to hold it properly.
