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!

Makes Cleaning Easy And Fun!

[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!

Shiny!

[This review was collected as part of a promotion.] Easy way to get sparkling clean windows. Comes with a concentrated solution and spray bottle/cleaning pad combo. The vacuum squeegee is cordless, which makes it nice and portable! This window cleaning kit left my windows shiny.

No streaks and simple to use plus I found somethin

[This review was collected as part of a promotion.] I am thankful that I received this Karcher WV 1 Plus for free to review from Influenster and Karcher. This is such a helpful device when it comes to cleaning big windows, sliding glass doors, mirrors, glass shower walls, and shower doors. It comes with cleaning solution where I just put one cap into the provided spray bottle, fill it to the max and screw it into the scrubbing mechanism. Then I manually spray and scrub or wash the glass. Next I take the rechargeable window vacuum and suck it clean. I love how there are no streaks left behind! The squeegee is easy to clean and it slips out the side. The dirty water tank simply twists off for dumping (which is attached to the vacuum by the handle. It can be used without being plugged in so I can take it anywhere like to clean my RV or vehicle windows. This is kind of fun to use. I am going to keep it in my bathroom because I discovered another use for it in there. I often notice that when my kids get out of the shower or bath, they leave puddles on the ground. We usually dirty towels to mop it up. Well not any more. When the shower sprayed the door and leaked onto the floor while the door was open this vacuum just sucked it up with no problems and quickly. It is my new device to clean up small puddles from dripping children.

So useful!

[This review was collected as part of a promotion.] This window vac is wonderful. My back window in my car gets so dirty and a car wash can only do so much. This window vac removed all the gunk and filth and left my back window sparkling! It's so easy to use and holds a good charge. It's durable and I love that it can be used on your car, shower, windows, etc. easy to store and clean too!

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.

Vacuum window cleaner

[This review was collected as part of a promotion.] I have never thought I would need a vacuum window cleaner but I am a convert. This is a unique product with two components: a spray bottle with attached microfiber scrubber, and a vacuum squeegee. I tried this cleaner on mirrors, windows, and my guest shower door. It is quick and effective and not too noisy. It leaves minimal streaks though it does still need a finishing cloth to get small streaks or drops left behind. It is somewhat tough to navigate around handles or at the bottoms where you have to turn the vacuum sideways to clean. It takes up a significant amount of space in the cabinet as well. I will likely use it regularly to clean my large bathroom mirror and windows in my home. I recieved this in exchange for my honest review. I overall would recommend it.

It's ok

[This review was collected as part of a promotion.] I wasn't super impressed with this setup. It is 2 separate pieces. It has a spray bottle with cloth attachment and the other piece is a squegee with a vacuum. The squegee is loud and leaves behind streaks. Id rather use a cleaner and paper towel for the windows and doors.

Window cleaner

[This review was collected as part of a promotion.] Honestly so much more complicated than it needed to be. I diluted the concentrate and added it to the spray bottle. Sprayed down the shower door. Than had to go back with the squeegee vacuum and suck up the spray. It did not get all the soap scum but did make it slightly better. I will have to go back over with a second bathroom cleaner. I would say this is really only good for windows.

Not The Best

[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.
