Kärcher 16332220 WV 6 Plus N Window Vac, 10 W, 240 V, Yellow/Black

Product Information

The Vac comes with a 280mm suction nozzle designed to let you get right into the corners and edges of every window. A smaller nozzle is also available as an accessory, ensuring every cleaning task is covered. 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. 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.

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.

Price alert

So, while all WV models provide excellent performance and value for money, make sure you read each review to choose the right model for your requirements. If You’re in a Hurry… 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. If you’re looking for the best window vac and don’t mind paying a bit extra to get it, then the WV5 Plus N is the one to get. It ties with the WV2 Plus N for run-time and versatility, but adds several important features for power users. Cleaning windows can be a frustrating job – especially without the right tools. Drying a glass window pane with a cloth is likely to leave smears, but letting the window dry naturally causes streaks.

Extension Poles. These attach to the body of the window vac so you can clean taller windows without a ladder. If you have skylights or large windows, an extension pole is a useful accessory to buy. 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. 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. 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 judge how comfortable each window vac is to hold and empty. We also do this wearing Cambridge Simulation Gloves – a piece of kit that helps replicate the experience of users who suffer with limited hand movement.
