Review // Karcher Window Vac WV2

karcher super bloggersA few weeks ago I received a very exciting email from Kärcher asking me to be a ‘Kärcher Super Blogger’ for 2015. As a family of rather house-proud clean-freaks, this ambassadorship is right up our street so I swiftly accepted! If you’re not familiar with Kärcher by name (I’m pretty certain you will have seen one of Kärcher’s distinctive yellow products in your local DIY store), they are one of the largest maufacturers of cleaning equipment.

Over the course of 2015, we will be bringing you news of Kärcher’s brilliant products to help with cleaning around your home and we’ll be putting various Kärcher products through their paces and sharing our reviews with you.

First up we have been asked to review the Kärcher Window Vac WV2. This is one of those products that friends have always raved about but I have always been slightly skeptical. Why do I need to vacuum my windows when I can just Squeegee them?! But boy was I wrong. This unassuming little gadget, is brilliant!


The Kärcher Window Vac does exactly what it says on the tin; it vacuums up all those dirty soapsuds, leaving your windows streak-free with minimal effort. The new, improved, WV2 Window Vac (it’s the second generation one) has been designed to make cleaning smooth surfaces even easier than before and I’ve been really impressed. It’s easy to assemble (the only assembly required is slotting the rubber blade into the unit), lightweight, comfortable to hold and a doddle to use.


With it’s lithium ion battery, the WV2 can clean up to 75m² on one battery charge, which equates to about 25 minutes of continuous use; plenty of time to get your windows sparkling.

So how does it work?

Firstly you need to clean your windows as per your usual method; I spray the windows with glass cleaning solution and wipe over them with a damp cloth to ensure that all the dirt is ‘loose’. Then use the Window Vac in steady strokes from the top to the bottom of the window pane and all the moisture will be sucked into the device leaving your windows streak-free and gleaming.


For the first time in forever, I actually enjoy cleaning my windows and bi-folds! It’s pretty satisfying seeing all the dirty water collecting in the water reservoir tank on the front of the Vac and it’s definitely much less effort than any other method I’ve tried previously.


Despite it’s name, the Kärcher Window Vac isn’t just limited to cleaning windows. It can be used on all smooth surfaces, such as mirrors, bathroom tiles, work surfaces and shower screens and it’s also great for cleaning spills (handy for our not so graceful little people) and sucking up condensation.

In my opinion, the Kärcher Window Vac WV2 is an outstanding piece of kit and a game changer for cleaning windows. The windows are, without doubt, as perfect as you’ll get them and it most definately out-performs all the other methods i’ve tried in the past, including vinegar, lemon and scrunched up newspapers! There is no dripping of dirty water and as it takes minimal effort, I know this is one product I will be using regularly in our home from now on.


The Kärcher Window Vac WV2 is currently on sale for £42.95 on Amazon, £44.99 at John Lewis for those of you that prefer to purchase from a ‘real’ shop and via many other retailers both in-store and online. 

I have reviewed the WV2 model, but there are other models available including those that include a spray bottle, micro fibre head, cleaning solution and a narrower 170mm suction blade (the standard blades are 280mm), so do check out the different options on the Kärcher website. You can also keep up to date with all things Kärcher on FacebookTwitter and YouTube.

Disclosure: We received this product free of charge as part of our Ambassador programme and all thoughts, opinions and photographs are my own.
