If you’re tired of streaky windows, grubby shower screens, or smudged mirrors, the Kärcher WV2 Plus N handheld window vacuum cleaner could be your new best friend, and it’s currently 31% off on Amazon.

It's usually priced at £79.99, however, Amazon and Kärcher have both reduced it to £54.99, offering an easy way to remove moisture from glass, tiles, mirrors, and shower doors. It's also suitable for tables and worktops.

Window vacs are designed to make cleaning smooth surfaces quick and easy. It sucks up water, condensation, and cleaning fluids, leaving them streak-free. Many models come with different nozzle sizes to reach narrow corners or lattice windows, and dirty water is collected in a tank that can be emptied without touching a drop. It’s a faster, cleaner, and more efficient alternative to traditional squeegees or cloths.

The Kärcher WV2 Plus N weighs less than 1kg, and comes with two accessories: a 280mm standard nozzle for large glass areas, and a 170mm narrow nozzle for tighter spaces like lattice or Georgian windows. It's cordless and has a battery time of 35 minutes, and takes three hours and 50 minutes to fully charge. It also comes with a spray bottle and wiper, a microfibre cloth, and 20 ml of window cleaner concentrate.

To use, apply the cleaning solution to the area and wipe thoroughly with the microfibre cloth. Then, turn on the machine and suck up all the dirt, grime, and detergent.

On Amazon, there are plenty of satisfied customers, with the device scoring a respectable 4.5 stars out of five. One happy shopper said: "Great product. I was able to clean the inside and outside of all windows at my semi-detached property, including a large set of French windows, in about 20 minutes." Another content buyer wrote, "Amazing! Don’t know why I haven’t ordered this before. Quality is brilliant. So easy and quick to use."

Not everyone was completely sold with a few purchasers mentioning that it still left smears on windows. However, others said this was only until they got used to it. Someone wrote: "Fewer and fewer streaks as one gets more adept at using it."

For an alternative, Argos sells the Tower TWV10 cordless window vacuum for £26, offering up to 30 minutes of runtime and fully charged after three hours. Meanwhile, Halfords stocks the Daewoo Hurricane Clearvac, also £26 reduced from £29.99, which includes a 300ml spray tank so you can apply cleaning solution directly to glass.
