Customer Reviews for Karcher - WV 6 Rechargeable Window Vac: Power Vacuum, Electric Squeegee, 11" Blade, Spray Bottle, Microfiber Pad & Concentrate

Verified Purchase:Yes
Easy to use, battery length was sufficient, the solution tank could be bigger. This product worked well except for the outside panes. We live in a dry climate and the window was no longer sufficiently wet by the time I used the vacuum to collect the water. In these instances the windows were streaked. When using the window vac, you need to be fully committed to cleaning the entire window and not just the smudges such that our pups leave on the windows. Spraying, wiping and then vacuuming is one more step than I need when I use our Karcher steam cleaner to clean the windows - the plus side of the vac is that it is cordless. I love the steam cleaner for cleaning our windows - so the jury is still out on which product will be my go-to for window cleaning.
I would recommend this to a friend!

[This review was collected as part of a promotion.] I never thought I would need something like a window vaccum, but here we are. It actually makes cleaning my windows easier. It works really well and does not leave a lot of streaks. I like that it is cordless and handled making it easy to carry around. Great value file the price.

[This review was collected as part of a promotion.] This product has been a game changer when it comes to cleaning our windows inside the house. It comes with multiple attachments to get each job done, liquid cleaner, and all the pieces needed for shiny windows. It is very durable and a great price for all you get too! I love how easy and simple the directions are also. It only took us around 15 minutes to get it set up and ready to use. This product has quickly became one of my husbands favorite gadgets for cleaning around the house! 🪟
This product comes with a charger and also lasts 100 mins cleaning. 10/10 everyone needs this!! 🧽

Makes window & mirror cleaning a breeze!

[This review was collected as part of a promotion.] This makes window and mirror cleaning so much easier and faster than your regular spray and paper towel method! I love that the microfiber pad and squeegee can be removed and cleaned on their own and the 100 minute battery life allows me to get every single mirror and window in my home clean before it dies! Both handheld pieces are super lightweight and easy to hold. I read that it also works on tiles so I’m excited to try it in my shower next!

Beyond impressive

[This review was collected as part of a promotion.] The performance is impressive . it removes water and residue in one smooth pass and leaves the glass genuinely streak free. Windows, mirrors, shower doors… everything looks clean without needing to go over it multiple times.
The experience itself is very satisfying. It’s easy to use, feels welldesigned, and doesn’t splash or drip like traditional methods. The battery life is a huge plus, it lasts long enough to clean multiple rooms in one go without worrying about recharging. The battery indicator is also a nice touch, so you always know where you stand.
In terms of quality and durability, it feels solid and well-built. This isn’t a flimsy gadget it feels like something made to last. It does get a bit heavier when the tank is full, and charging isn’t the fastest, but neither of those take away from how well it actually works.
Overall, it’s efficient, effective, and makes window cleaning quicker and less annoying. If you care about clean glass and saving time, this one really does the job.
