I am thoroughly impressed with this system! My windows look fantastic and it is easy to clean them. First you spray the cleaner (you dilute a capful of the solution so the bottle should last awhile). Swipe the window with the pad on the spray bottle. You can clean longer with the pad if the window is extremely dirty. Next, turn on the gadget and squeegee the window. It is pretty amazing. I do use some lint free (cheap) paper towels in case there is some streaking but it is super easy to polish that away. I have never been able to clean windows that look this clean and it is quick! I am happy that I purchased this system! The clean up when putting this system away is easy too.
This speeds up the process for cleaning the inside windows...outside is another issue (at least in our warmer climate like AZ). Lots of streaks when cleaning outside, it's almost easier to use the old-fashioned squeegee method instead. Making sure there is absolutely no sun, cool weather, etc seems to make it work a little more efficiently though.
Nice not having to drag a bucket of water around. The power squegee is also cleaner than the manual method. It's a little difficult to squegee at the bottom especially the sliding glass doors. The glass cleaner does do a better job of just water as the power squegee doesn't suck up plain water very well. I did my bathroom mirrors and it is the cleanest it's ever been. Very little streaking and I assume that will get better as I use the tool more.
I bought this windows vac because I have a lot of windows to clean. I am a bit I am I I am disappointed because I can not clean all of my windows! I have a lot of small-paned windows that cannot be cleaned by the WV6 because of the length of the tool. They should have built an adapted blade for smaller windows. But for my big windows, it works very good. Too bad!
I would recommend this to a friend!

Dear Kärcher Customer - thanks for your review and the feedback. We do offer a smaller nozzle that you can attach to your WV6 Window Vac - here is the link: https://www.kaercher.com/us/accessory/wv-6-small-suction-nozzle-26335120.html
It is called the "WV6 Small Suction Nozzle" and it is only 6.7" wide, so should be able to clean your smaller panes.
The product doesn't vacuum up the dirty water from the window at all.
No, I would not recommend this to a friend.

Dear Kärcher Customer, thanks for the review – may we offer a few suggestions to alleviate the issue? A) Ensure that the waste water container is not filled to above the “MAX” fill line, and that there are no clogs in the connector at the top. B) Make sure you start with plenty of charge in the battery (onboard indicator will tell you how many minutes of use are left), and you’re pushing the squeegee blades onto the surface enough to make good contact without pressing too hard. C) You can also remove the squeegee head and run water through it to make sure it isn’t clogged.
If after trying those tips it still won’t pick up any water, please contact our customer care team at 800-537-4129 or karcher-help.com. Your WV6 Window Vac is covered by a one year warranty and our Rapid Exchange Program.
