Kärcher has improved the original Window Vac again and developed an even more flexible model featuring innovative blade technology and longer battery running time – the WV 6 Plus. The new longer suction blade allows you to remove excess fluid from entire surfaces in just one charge. The Window Vac's extra-long battery running time of 100 minutes means you can keep going for even longer. You can plan your cleaning precisely thanks to the display which indicates the remaining minutes of running time. As usual, the intelligent combination of spray bottle and microfibre wiping cloth, along with the suction function on the Window Vac, guarantees extremely effective cleaning and sparkling clean windows – with no streaks or residue. The ergonomic WV 6 Plus Window Vac by Kärcher also allows you to clean your windows in an especially hygienic way, because you do not come into direct contact with the dirty water.

I purchased WV6 Plus and an extra blade about a month ago. I have previously used over 3 different products to clean my tall and several windows. Honestly, the best product for ever!! Very easy job and it is done to the perfection too. Pleasure to see in the dirty-water tank amount of dirt gathered. All my previous products are giving streaks along the edge of the squeeze but not with this WV6 Plus. My guess thought, how long will this last for??

Amazing wee machine. I had an earlier model about 7 years ago and it stopped working after about half a dozen uses. Very disappointed and said I’d never get another. I ended up getting this one based on other reviews and I love it. My 16 year old son even likes to use it. Does the job well

Initially I wanted to clean my windows, which being South facing, were becoming quite dirty and damp from the winter weather. I have now moved on to using the Window Vac for just about everything with a glass or mirrored surface! It took me a little time to get the best results but that was more about how I was using it, not the actual appliance. It comes with a good spray bottle/mop, which you use first - then go over with the Window Vac, sucking up all moisture along the way. Having only single glazed windows, I've even been using it on cold mornings for condensation, as it is so quick and the battery life is really good! Thoroughly recommend and should have bought it ages ago.

I am very happy I have purchased this product. Our house has some 200sq m of glass. This Window Vac has cut down 75% of cleaning time for me. Cleans better than with previous method (spray/wipe/streaks/moving and setting up ladder, etc). Odd streak happens with this as well but is easily wiped off with dry rug. I have used it once so far and am looking forward to try it with extensions.
With a zillion large windows in our home, I decided to give what I strongly suspected a gadget, a try. It really does work! You do have to use fair amount of pressure when vacuuming the window, & move slowly or you’ll get streaks, but it’s still faster & more effective than any other cleaning method I’ve tried. Great on condensation & shower doors too! It’s brilliant.
This window cleaner is excellent and saves. alot of time and mess.Like anything it depends on how dirty your windows are to start off with.You can’t expect to have filthy windows and expect them to come out crystal clean, remember you are spraying then wiping with the cleaning cloth then vacuuming, if your windows a filthy what do you expect(streaks)I have a house full of windows and doors and this vac is the best thing I’ve ever bought.The more you use it the cleaner your windows will be so there will be no streaksalsoit is that easy to use it makes it a pleasure to clean.The silicone blade is the best as it flex’s right down to the bottom
Purchased this item a little while ago. And now feel I can give it a decent review.I’d been a bit reluctant to purchase one of these as I originally felt it was a bit gimmicky and that I wouldn’t use it…. Well I was wrong. I use it weekly even just to clean the car glass (windscreen and windows), it has made cleaning the outside windows on the house a breeze (we have lots of windows…) I do struggle sometimes to not get streaks on the glass but I have found it works best when there’s lots of the glass cleaner used and don’t be shy to give a few extra sprays of the solution before vacuuming the glass. Trust me that’s the trick to smear free glass with these.The thing I love most about this particular model is that it can be used at any angle, sideways, flat and ...

None of the other models can do this and I would never be able to cope without it having this ability.Overall it’s a great design with an amazing battery. I’ve owned it for months and it has only had a few charges. I did our whole house and only used 40% of the battery!I highly recommend getting one of these and if you have the extra money to spend to get this particular model I highly recommend it!Thanks Mitre 10 and Karcher.
Where has this been all my life! Decades of sopping wet towels every single winter, No More! I use the water sucked up to water the pot plants on my way around the house. So easy to use, take apart, dry off and put back. Battery lasts AGES! If you want one for the condensation in older homes, Buy it! I can only imagine the great job of cleaning windows with the supplied kit but condensation...perfect!
The squeegee is garbage… leaves streaks with every pass. I bought the karcher brand liquid concentrate to go with it too. The spray bottle with scrubbing sponge is great, very handy and the sponge washes out well after use, but that’s not worth $195. You’re paying for the vacuum squeegee, which is a waist of time. It does suck up the liquid, but leaves perfect streaks about 10mm apart for the whole width of the squeegee. I’ve done all our windows and mirrors and they’re all now streaky. The streaks really stand out when the light hits it. I would have been better off buying a decent manual squeegee, a bucket and some cleaning singes and rags. Waist of money!
The box was missing most of the parts. No charger, no spray bottle (but still had the flat attachment?), no detergent, and only the large blade (it’s supposed to come with a mini one too). It screaches horribly when using (no - it’s not from a lack of liquid or pressure or the angle I’ve tried it all)… Had the WV2 before this and wish I hadn’t wasted the money upgrading. It’s a massive bummer.
