This is easy to use vacuum cleaner. I washed 16 windows for 2 hrs by using it. No stains, no drips!This little guy makes my life much easier!

We live in a condo with an enclosed shower with mold and humidity issues. After every shower we squegee the glass and walls to minimize the moisture left behind. The Karcher product we purchased removes about 3/4 cup of water from the glass and tile walls of our shower. One hint for use- hold the vaccum parallel to the surface. If it is not held parallel and the bottom of it is not close to the surface, it works more like a squegee with water streaming down the walls as it is being used.

I just busted this out of the package and thought for sure I would be returning it - seemed too light weight and the motor seemed to be kind of weak....yep, I was wrong - light weight was good and the suction power was more than adequate! Ended up literally cleaning every flat surface in my house - windows, mirrors, shower doors, even did the sub zero frig panels - was awesome!!!!

While it still takes some time, and effort, this device eliminates the worst part of cleaning windows… Trying to remove all the smudges, streaks, and little bits of paper towel from your freshly washed windows. My windows have never looked so nice. Tip: have a dry paper towel with you so that after you’re finished using this on a window, you can clear up any small remaining smudged areas.

My house has 35+ window panes. I no longer need to carry a bucket of dirty water (and having to change out the water all the times) with a bottle of Windex and several towels (for pre-cleaning, with Windex, and drying) around the house and inside. Our window cleaning that used to take us more than 2 hrs was done in less than an hour upon using WV1 Plus the first time. It was so easy to use and I only needed to refill once. It's a joy to clean windows now!

I purchased the WV1 Plus about 2 months ago. I use it to clean all types of glass (shower doors, mirrors, windows). The product cleans really well and leaves relatively few streaks (nothing a rag can’t get). I like the fact that my paper towel usage to clean these things is now zero.

I have lots of windows, and it's a major project. The WV 1 Plus is easy and quick to use. I can do as many or as few as I feel like doing. One draw back is the ability to get to the bottom of the windows; I have deep window sills. I need to tilt the unit and do some manual wipe up.

[This review was collected as part of a promotion.] Overall this is a great little cleaning system. It makes a task no one likes to do and makes it a breeze. It’s easy to take from room to room doing windows and mirrors and is quiet enough to use any time of day, such as early mornings when the rest of the household is sleeping. The instructions for use are clear and within the first window or two, you have the usage down to a science. I’d love to see a system that is all in one, which is why I would rate this 4/5 stars - this would allow for ultimate convenience and portability.

I bought this to clean condensation from single pane windows in my 1950s home.so that the sills don't rot.. Works great! It makes window cleaning a cinch, so I will clean them more often. 4 stars because it does seem to leave a spray of dirty water on the white sills for me to wipe up.

I live in a florida condo varying sized windows and doorwalls. The product died very quickly after only a few windows and the squeegy needs to be wider. Long life battery or more than one is needed. Probably good for small jobs. I'm going to look for a larger one now.
