Wired Magazine

"Kärcher's New Window Vac Is As Good As Advertised"

"Does it actually leave your windows streak free? Yes, it does!"

(review of previous generation model WV50)

New York Magazine / Strategist

"... it has become my go-to tool in keeping my shower clean. Think of it as a squeegee on steroids."

"It sucks up excess water so you can also get rid of mirror condensation in no time, and you can use it to clean bathroom tiles or kitchen counters, too — anything with excess water, really."


"It is affordably priced when you consider you will be dramatically reducing your costs for paper towel usage that comes with window cleaning."

(review of previous generation model WV50)

Little House on the Corner

"I totally admit that I’m surprised by how much I like the window vac. It sucks up the dirt amazingly well and is really light and easy to use. "

Frequently Asked Questions

Cleaning with paper towels requires a lot of physical effort, is time-consuming and inefficient. The results are usually less than satisfactory, leaving behind streaks as well as lint. Additionally, there is a lot of waste, often a basket full of expensive paper towels! The Window Vac eliminates the need for paper towels altogether. All you need is the Window Vac, spray bottle and cleaning solution – everything included in this offer!

The Window Vac excels at cleaning windows, of course, but is also great for cleaning:

  • mirrors
  • shower doors and tiles
  • kitchen surfaces
  • appliance doors
  • glass tables
  • vehicle windows and more!

Please note that the Window Vac it is NOT designed to pick up:

  • large spills
  • harmful or caustic liquids (including rubbing alcohol and bleach)
  • solid matter

The WV1 Window Vac is very light, weighing in just a little over a pound! (17 ounces) This makes it easy for users of all ages to hold and operate.

The Window Vac provides 20+ minutes of continuous cleaning time after each full charge. That is more than sufficient to clean the windows in an average size home.


When we first launched the Window Vac in North America it was called the WV50 PowerSqueegee, but is now called "Window Vac" so that it has the same product name worldwide. 

Currently we only offer the WV1 Window Vac model in the US. Other models will be added to this page if/when they become available in the US.

The WV 1 Window Vac is made in our plant in Italy.

Accessories and Window Cleaner Concentrate

The WV1 Plus battery-powered Window Vac contains everything you need to clean most home windows – but what if you need to clean overhead windows that are difficult to reach?

Extension Kit for high windows

The optional extension kit makes cleaning high windows a breeze. You can use the extension pole to both apply cleaning solution and then to vacuum it away with the Window Vac attached. Forget climbing around on ladders to clean your overhead windows – this Window Vac extension kit enables you to clean quickly and safely from ground level. 

Kärcher Window Cleaner Concentrate

While you can certainly use your favorite brand of cleaning solution with the Window Vac, many users prefer our specially formulated Window / Glass Cleaner. It cleans brilliantly and also makes rain run off more quickly (and keeps windows and other surfaces clean longer!), while imparting a natural fresh scent.

It's also highly concentrated – you only need to mix one capful of the concentrate with seven ounces of tap water!
