WV5 Premium is rated 4.2 out of 5 by 72.
Rated 5 out of 5 by from Very Useful! I bought the Karcher Window Vac last month - to use on our tent! Yes, you read that right - our tent! If it rains before we have to pack up (or just heavy dew in the morning of pack up) this takes the water off a treat. We still have to put the tent up when we get home to complete the drying process but this makes it soooo much quicker! Oh, my husband also uses it in the mornings to clear the windows on the school minibus he drives every day. Again, much easier, quicker and cleaner than using the old squeegy thingy! It works well in the shower too and leaves it sparkling. Must use it on the house windows one day............

Rated 5 out of 5 by from Essential item, wouldn't be without it Have had this product for three months now and am certainly reaping the benefits over the cold winter months. Instead of wiping the insides of our windows with cloths to remove condensation every cold morning, we now use the WV5 and it is Invaluable. Easy to use, quick and quiet. The ability to change the cleaning head size is very useful for different window pane access. The water container is easy to empty. We also use it to clean our glass shower screens and bathroom tiles and mirrors, all very successful and time-saving over traditional methods. We have used it successfully to clean outdoor windows but this is not a priority in our house!

Rated 4 out of 5 by from Honest Review Absolutely brilliant until it wouldn't hold a charge. However, contacted customer services and they've offered a replacement albeit a bit slow but at least they've accepted it's faulty. Looking at other reviews it appears this is a common fault which is a shame as when they work they're fantastic. Some reviews complain of streaks on glass surfaces, but if the spray detergent is mixed correctly this doesn't happen. I hope now Karcher will fix the charging issues and I can score this 5 stars ✨

Rated 5 out of 5 by from Great Product We bought this product several years ago and it has been great for cleaning the windows and also drying off the car......we use it every time we clean it and it saves a good deal of time. It is not completely without problems though. Firstly, it stopped working for a while but it did then suddenly resurrect itself. Then it does have a design fault in that at certain angles the water tank drops off when pressure is applied. And, finally, I would not recommend that you by the window sprayer as the cleaner is expensive and washing up liquid and a cloth work equally as well.

Rated 5 out of 5 by from BETTER THAN EVER!!! This is the FOURTH Karcher Window Washer that Ihave purchased! Two of the others were gifts to my neighbours (who were delighted by their ease of use and efficiency). The third was mine until two months ago - when my daughter wanted to wash the windows of her new house, and had mine as a gift. However, I felt so bereft, that I just HAD to have another one - and treated myself to the top-of-the-range WV5 Premium. I thought that the original washer was exceptional - and now you have improved on perfection!! Many Congratulations from a very, very satisfied user!!

Rated 3 out of 5 by from 280mm adjustable width head problem Ive only just bought this and cleaned all my windows easily using the compact head. However, I found the large 280mm head with the adjustable width. next to useless, leaves so many lines that I had to wipe it clean with a cloth. so will try and exchange the adjustable head

Rated 5 out of 5 by from Fab for windows, and lifesaver for spills We bought this to encourage us to do a better job of cleaning windows, including a conservatory roof and two bifold doors - lots of glass with lots of sticky kids' fingerprints. It does it brilliantly. Very easy to use, and leaves the glass much clearer than with a glass cloth or chammy. It only needs a very quick wipe to tidy up edges. It also saved us when the kitchen tap was left on and the worktop ended up with a ¼ inch of water pouring off. Great for sucking up quickly.

Rated 5 out of 5 by from Does exactly what we expected A friend of ours had one as she lives in a very hard water area and needed something to prevent a lime scale build-up on the shower screen and bathroom walls. I was sceptical but tried it when staying at her house and was amazed at how effective it was at both removing the water and leaving the glass screen streak free. based on this I purchased one and so far I am absolutely delighted with it as it does a great job. I am not the greatest window cleaner in the world but I can honestly say that for the first time I have streak free windows.
