Not The Best
on April 4, 2026
Posted by: JessicaM
[This review was collected as part of a promotion.] This product was a miss for me for a few reasons. To start, the microfiber pad for the spray contraption was missing so I tested the product with just a regular microfiber towel. Mixing the concentrate into the spray bottle is just a messy process. You have the concentrate dripping down the sides of that bottle and then while filling the spray bottle bubbles foam up and spill down the sides of that. The rechargeable feature on the squeegee is nice but the cord fits very loosely into the charging port. The ergonomics of the product is nice. It does clean windows effectively. It is just a lot of work and mess for cleaning a window.

Easy to use!

[This review was collected as part of a promotion.] Directions were easy to follow! Product worked so well!! The vacuum portion was a lot quieter than i expected, so I was happy with that!! I found it worked better when you spray some of the solution, loosen it up with the microfiber and then spray more of the solution and use the squeegee vacuum bit! It’s lightweight and easy to manipulate! It’s easy to clean and pull apart and put back together! I’m happy with this!!

Easy to use, works like a dream

[This review was collected as part of a promotion.] These was so easy to use and it worked so well! We have a German shepherd, so nose prints are always a battle at our house. This not only cleaned them without any residue with the cleaner included, but it also left it streak free!

It works but takes more time
on April 12, 2026
Posted by: MichaelaK
[This review was collected as part of a promotion.] I received this window vacuum complimentary in exchange for my honest review. I was genuinely torn about this one. It had worked pretty well, but I feel like it doesn’t accomplish anything that I wasn’t able to do without it before. Neither it feels like it makes the cleaning easier or faster compared to using a normal squeegee. I enjoyed using it (it’s easy to hold and use) but it made me equally frustrated. The main point of frustration was that before I made it to the right side of the window or glass door, the water with the cleaning solution all dried up, so then I had to make the other side of the window wet again to be able to vacuum that part. But because of that interruption, it seemed to cause smudged lines in the middle part. So then I had to make the middle wet again a bit to fix that and a 5 minute task turned into a 20 minute task. Also when cleaning windows with a windowsill, I wasn’t able to use the vacuum all the way to the bottom of the window because per instructions the vacuum needs to be used at a certain angle to avoid streaks and the window sill prevented me from either keeping the angle or going all the way down, causing more streaks or smudges at the bottom. So then I had to make the bottom wet again, and you get the idea now..
On a positive note, it’s pretty quiet, it was easy to assemble and easy to use overall if you’re okay with having some smudges on the glass and then getting them out with a glass cloth. After cleaning is done, it needs to be disassembled to be cleaned, and I don’t know why, but to get the squeegee off the vacuum you need to press this button with a screwdriver. I don’t understand why they didn’t make it a regular button? It seems like too much hassle. Unfortunately, I wouldn’t recommend this product.

Impressive window helper!

[This review was collected as part of a promotion.] This is quite a useful little device and system! After I watched a quick video on how to start, I was soon cleaning my first windows. You do a quick swipe of the spray bottle filled with solution and attached cleaning cloth, followed by the squeegee vacuum. I was super impressed with how the finished windows came out dry and beautifully clear! I actually am looking forward to cleaning more!

[This review was collected as part of a promotion.] This Window Vaccum from Karcher makes it so easy to clean my windows. The fact that I can also use it on my shower glass, mirrors and windows is a game changer.

Makes Cleaning Easy And Fun!
on April 13, 2026
Posted by: LindsayS
[This review was collected as part of a promotion.] I was skeptical at first. I wondered if this was going to be a gimmick or more of a hassle than traditional cleaning methods. Then I tried it and.. wow! This product just changed my cleaning game.
It’s a rechargeable window vacuum squeegee that comes with a spray bottle with an attached microfiber pad. I’ve used it on my shower doors, bathroom mirrors, my windows, basically everything with a glass surface. Our house has A LOT of windows and the window spray and paper towel method of cleaning them was time consuming, exhausting, and wasteful.
This tool is lightweight and efficient. I was able to clean 20 windows in under 20 minutes! It takes a minute to get the technique down for streak free results (spray generously, wipe with pad, then vacuum in smooth overlapping strokes), but once you do, it’s the easiest, shiniest streak free ever!
My husband keeps swiping it to clean his car windows and he actually enjoys using it around the house. I’m also impressed on the battery life as well. I’ve tackled several large cleaning projects for over several hours and it’s still going strong on a single charge.
This has genuinely simplified my cleaning routine and I love it. I highly recommend!

Works great and easy to use

[This review was collected as part of a promotion.] I’ve been using the Karcher WV1 Window Vac and it’s one of those tools that makes cleaning feel much easier. It’s lightweight, compact, and super easy to use.
Besides tools, the kit comes with cleaning solution to start. The instruction is easy to follow. The cordless handheld vacuum leaves surfaces streak free while sucking up all the dirty water, no more drips running down or wiping over the same spot multiple times. It’s especially great for shower glass and bathroom mirrors.
The battery life is decent for quick cleanups, around 25 minutes per charge. I still need to spray and wipe beforehand. It doesn’t replace cleaning but it makes the final result look so much better and saves time.
