As with all the WV range, the WV2 Plus N Yellow is great for cleaning windows, tiles, mirrors and other surfaces around the home. It’s relatively lightweight, includes a spray bottle kit for the cleaning solution, and is simple to empty. The intelligent combination of spray bottle and wiper guarantees extremely effective cleaning. The handy device then has no trouble vacuuming away the water from the window every time you use it – with no dripping dirty water and no streaks. When compared with conventional methods, manual cleaning is noticeably easier and three times faster than before. The convenient battery operation and the compact design guarantee maximum flexibility when cleaning household surfaces. Features & Benefits: Let’s start with the similarities between this model and the WV2. It features the same basic design, 100ml dirty water tank and LED charge display. The 250mm cleaning head does an excellent job of leaving streak-free windows and other surfaces, while the lithium battery doesn’t lose suction as it gets low on 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. Keep in mind that window vacs are typically only useful for cleaning ground floor windows. Extension poles can help reach higher conservatory glass or patio doors, but they are difficult to use on first floor windows without a ladder (which comes with its own dangers.) Of course, they are also great for cleaning shower screens, shower doors, and car windows.

Interchangeable suction heads: Most window vacs come with a 280mm suction head as standard, but many include an additional smaller head for fiddly jobs such as leaded windows and front door panels. Pivoting suction heads can also help to get into awkward spots. Related Article: How to Use a Karcher Vacuum Cleaner to Clean Windows What Accessories Are Available? There are several key differences between the WV1 and WV5 though. The WV1 only has a 25-minute run-time and no option to swap the battery, so it may not be the right choice for cleaning lots of windows at the same time. It also only has a single 250mm cleaning head – the smaller 170mm head isn’t included.

Banish condensation and streaks with the best window vac for cleaning your windows, mirrors and more

Karcher window vacs – also known as the WV range – are amongst the top products on the market. All WV models are powerful, come with lithium batteries to prevent suction loss, and are great for streak-free windows, tiles and mirrors. When it comes to value for money, the WV2 Plus N Yellow is probably the best option. It’s cheaper than the WV5, yet still provides a 35-minute run-time and excellent performance. We think the WV2 Plus N provides the best balance between price and performance, which is why it’s also our #1 window vac. If the WV5 is the most advanced Karcher window vac, the WV2 Plus N Yellow provides the best balance between performance and affordability. It’s not the cheapest – that title goes to the WV1 – but has a 35-minute run-time, two blades and excellent window cleaning performance. One of the most important additions is the removable battery. The WV5 is the only WV window vac to include this feature, which allows you to swap the battery and continue cleaning (you’ll need to buy another battery though). The edge guidance function, which is effectively an adjustable roller so you can get right up to the edge of frames, is another welcome addition. For this reason, we recommend the WV2 Plus N for most people, as the smaller nozzle provides more versatility. And if you need a swappable battery and edge cleaning system, then the WV5 is clearly the superior vacuum.

Karcher Window Vac WV5: Best all-round window vacuum cleaner There are some important differences between the various models though. The run-time, working nozzle width and weight vary depending on which you buy. There’s also a reasonable difference in price between the cheapest and most expensive options. A common complaint about Karcher vacuum cleaners is that their instruction manuals don’t clearly explain how to use a window vac. Perhaps Karcher assumes everyone knows how to use one, but this doesn’t help if you’re buying your first window vac and would like detailed instructions.

Karcher has recently upgraded the WV2 to have a 35-minute run-time. This equals the WV5, which is another reason why we recommend the WV2 for most people. The lithium-ion battery also means it doesn’t lose suction power as the charge runs out. The cheapest WV vacuum cleaner is the WV1. While it doesn’t include many of the features found on the WV5, it provides great value for money and is perfect for smaller homes. Weight and capacity: A kilo may not feel like much at first, but after half an hour of holding the unit at arm’s length it will start to hurt – especially when it fills up with 300ml or so of dirty water. The bigger the tank, the more cleaning you can do without having to stop and empty it, but the heavier it will get. So, tank size is less important than leak-proofing and easy emptying. What extra features and accessories are worth having? When fully charged, the battery life of the WV2 is 35 minutes, enough window cleaning time for the average family home. An LED display lets you know when it's time to recharge the batteries. A full battery recharge from empty takes up to minutes depending on the model.

Cleaning extras: Many window vacs come with cleaning bottles, microfibre pads and even their own branded cleaning spray. While useful, these extras are unlikely to perform any better than the stuff you already have in your cleaning cupboard. We think the best Karcher vac is the WV5 Plus N. It comes with all the features of the WV2 Plus, but with an edge guidance system, LED battery light indicator, removable battery and two suction heads. If you want the best for your home, go for the WV5 Plus N. Smaller Suction Blades. Some models (such as the WV5 Plus N) come with both a large and small blade, but Karcher also sells blades separately. If you need maximum run-time, the WV6 Plus N is our top choice. It has a huge 100-minute battery life, along with Karcher’s edge guidance system and battery indicator. It’s worth noting that the WV6 Plus N doesn’t have a removable battery, however, so if that’s important to you go for the WV5. While the regular vacuum cleaner market has plenty of competing brands, Karcher dominates window vacs in the UK. Their WV series is powerful, lightweight and easy to use – not to mention available for great prices. In fact, the company’s models currently occupy both #1 and #2 positions on our list of the best window vacs.
