Kärcher WV Black Edition Window Vac

Product Information

The window cleaner has an exchangeable suction nozzle, letting it get to smaller areas and hard-to-reach places. 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.

Featuring up to 25 minutes of runtime for its 3.7V Lithium-ion battery, the WV2 window cleaner has a cleaning performance of approximately 75 sq. m (25 windows). Suction power is excellent and you get oodles of extras in the box, including a smaller head and microfibre attachment. However, what pushes the Bosch behind the Karcher and Vileda in our list is its failure, reported by some users, to clean quite as well to the very edges of your windows.This battery-powered product comes with a narrow suction nozzle in addition to a spray bottle, a microfibre wiping cloth and detergent. The nozzle allows you to clean even lattice windows and display cabinets. Features

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. We select top-selling window vacs from leading UK retailers and put them through a string of tough tests to find out which are the best.

It’s worth noting that it isn’t an essential cleaning appliance. It’s more of a handy add-on, as you can clean surfaces with spray and a cloth. But it did an effective job leaving areas streak-free, so it’s worth it if you’re looking for a simple way to keep on top of windows, mirrors and tiles. 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. 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.

Rechargeable Battery – The rechargeable lithium-ion battery cleans up to 70 m on a single charge - that's up to 45 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. What extra features and accessories are worth having? Extendable pole: A few models on our list come with, or are compatible with, telescopic or multi-section poles to help you reach high windows and skylights without wobbling up a ladder. On the downside, a pole can make the vac hard to control, especially if it’s heavy. I’ve only had the vacuum for three weeks, so time will tell if it’ll make a difference, but so far so good. Kärcher window vac: Our verdictNone 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.
