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.Among its many included accessories are a smaller 170mm suction head for hard-to-reach areas and a microfibre attachment to spread detergent on your windows. There’s a built-in LED battery indicator and you can buy additional batteries so that you’ve always got a fully charged one ready to go. 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.

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.

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 cheapest WV vacuum cleaner is the WV1.

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.
