Kärcher WV 6 Premium Window Vac

Product Information

Mind, Kärcher isn’t the only window vac manufacturer out there – you can see a few more brands in our guide to the Best Window Vacs– but since Kärcher invented the window vac and its range has been so favourably reviewed by other users, that’s the brand I thought I’d concentrate on. In true pedant style, I’ve worked out that the 15 interior windows in my open-plan lounge-cum-summer room would have taken about 10 minutes to clean using the Kärcher vac and 20 minutes using my paper towel system. Multiply that figure if doing the whole house inside and out– about another 20 windows – and you can see how much time could be saved using a system like this. Enough time to watch at least two episodes of Curb Your Enthusiasm, which, incidentally, I’m trying to curb while writing this article. Tests have shown that the vacuum can clean 300 square meters with one charge. You’ll probably be able to do your car windows, your home windows, and many of the surfaces in your bathroom without ever losing power. The vacuum removes moisture from flat surfaces, leaving them clean and free of streaks. Because the model runs on battery power rather than using a cord, you can use it for the windows in both your home and your car.

Thirty-five minutes is quite a long time when you’re just cleaning windows and bathrooms. Unless you have an exceptionally big house, you should have plenty of time to clear the grime and get a streak-free shine. Spurred on by the success on my bathroom tiles, I turned my attention to the shower screen – which was in a pretty dire state. Although we have a squeegee sitting on the tiles for use after each shower, we seldom use it – which results in a buildup of limescale on the shower screen. The WV 1 is the most affordable window vac option. Like the others, it comes with a three-year warranty when you buy directly from Karcher, and a two-year warranty when you don’t.

The water tank, which holds 150ml of dirty water, is also easily removed for emptying. Since dirty water takes some time to accumulate, you won't have the hassle of frequent emptying. The battery arrives with just six minutes of power, so I first needed to set the appliance to charge. This took no longer than a few hours, and I could watch the battery indicator count up, minute-by-minute. Once it reached 100 minutes, we were ready to clean up to 300m² on one single charge.

Unlike the other Kärcher window vacuums, this model has just one 250 millimetre suction head. It isn’t detachable and can’t be exchanged with other pieces. This means that it will take a little longer to clean large surfaces, and it might be more difficult to manoeuvre around smaller surfaces. The WV1 Plus battery-powered Window Vac contains everything you needto clean most home windows– but what if you need to clean overhead windows that are difficult to reach? The WV 5 Plus N is another one of the more advanced offerings from Karcher. The handheld window vac can be used on a variety of surfaces. Though it doesn’t match the previous option’s 100 minutes of runtime, it is equipped with a lithium-ion battery that lasts for a maximum of 35 minutes. The best window vacs you can buy in 2023 1. Karcher Window Vac WV5: Best all-round window vacuum cleanerYou can switch between the included 170 and 280-millimetre suction heads depending on the surface. Also included are a microfibre cloth, a high-quality spray bottle, and 280 millilitres of concentrated window cleaner. For best results, use with Karcher cleaning agents. These are eco-friendly and bio-degradable and cut powerfully through grease, dirt, insects and the drips and streaks left by water without damaging the surface. The battery indicator lights will let you know when the charge is low. There’s also an edge guidance system that makes it easy to clean along the edges of windows without missing any corners. You can manually adjust the edges to clean the entire surface. Since the battery is removable, charging is easy. These new window vacuums are basically squeegees, with a vacuum attached – an ingenious design that leaves your windows super clean, dry, and streak-free after washing. The set comes with a manually adjustable range. You can set it on a scale from 0.6 metres to 1.5 metres. Another great feature is the adjustable head, which lets you change the angle of the window vac. By doing this, you can clean under surfaces or on top of shelves without needing to bend down or use a ladder.

Streaky windshields are a big problem when soapy water isn’t given a chance to dry. This window vac makes cleaning your windshield easy, especially since the battery lasts for 100 minutes per charge. None of that would matter if the Karcher didn’t clean windows brilliantly – and that’s where it really excels. Suction is strong and efficient right across the nozzle, so you can clean and dry into the silicone seal around your windows. The finish is about as streak-free as a window vac can achieve, although you may want to give your glass a final buff with a dry kitchen towel. This model is a step up from the wv5 premium and is equipped with two exchangeable suction heads, one a smaller 170mm width and one larger 280mm, this versatile window vac works on mirrors, shower screens, tiles, and of course dirty or foggy windows.I had high hopes for the Karcher Window Vac WV 6's cleaning performance. I live in an old house with high ceilings and, therefore, have numerous tall windows to clean. The WV 2 Karcher window vac is one of the most affordable options from Karcher, but it still has the extra features you’d want in a high-quality product. The model offers up to 35 minutes of sustained battery life with one charge. Testers have been able to clean 75 windows with just one charge. In addition to working well on the glass of windows and windshields, this window vac can prevent streaks on: While window vacs are compact in size compared to some other household cleaning tools, keep in mind that you’ll be holding it up, one-handed, for up to 30 minutes. Also remember that the water tank, as it fills, will add to the overall weight.
