Rather than moving around buckets of water, squeegees and towels, a window vac is the best way to clean your windows. No matter how big or small the window, they are designed to leave a streak-free finish with ease.
For this example of how to use a window vac, we are using the best-rated window vac, which is of course the Karcher machine. This particular machine is the “Anniversary” model, which features additional performance and a black design.
How To Use A Window Vac
1. Wipe Down With A Cloth
Before using a window vac, we advise that you wipe down your window with a cloth beforehand. Depending upon how dirty the windows are, you may be surprised by how much dirt is actually on the windows as we show in the below photos.
2. Spray The Window With Cleaning Detergent
Using a window cleaning detergent of your choice, generously spray the window to be cleaned.
3. Agitate The Cleaning Detergent
Although optional, for very dirty windows, you may wish to agitate the cleaning detergent that’s been sprayed onto the window. This will help break down any stubborn dirt, which can then be vacuumed by the window vac.
4. Use A Downwards Motion To Clean The Window
For the best results, it’s advised that you use a downward motion to clear the soapy water on the window. It’s important that you avoid letting the soap dry on the window because this will ruin the overall appearance.
5. Empty The Tank
Depending upon the number of windows you are cleaning, you may need to empty the tank. This water may be dirty, so it’s advised that you pour it straight down the sink.
Our Top Tips
As you can see, using a window vac is very straightforward but there are some top tips that we’d recommend to make it even easier. For example, rather than using a set of telescopic ladders to reach high windows, many brands offer extension poles that simply clip onto the device. This avoids all the hassle of moving the ladders to each high window.
For tackling small windows, we highly recommend taking advantage of any smaller attachments that the brand offers. For example, Karcher offers several small suction nozzles for this exact reason.
Finally, to improve the overall finish of the window, it’s important that you don’t forget to clean the other components of the window such as the plastics/UPVC. Whether you use a dedicated UPVC cleaner or a diluted cleaner, cleaning the other parts of the window will vastly improve the overall finish of the window.
