I've tried out this glass cleaner, and my first impression was that the liquid dispenser doesn't close properly. When tilted even slightly, it starts to drip liquid onto the floor. Once I used the machine to clean the window, there was a noticeable improvement, but there were a few small issues. If you're someone who likes things to be just right, you might see that the absorbent bar leaves several lines on the glass, though you'd only notice if you were really paying attention. Also, the edges of the glass are not cleaned, leaving a dirty frame around it (you can see this in the photo I've attached).

I tested this product a few times and I really liked how it works. The kit is complete and you can choose the different parts for different sizes of windows. It's comfortable to use, not heavyweight. I gonna keep using and recommend for those who want to let the windows and similars looking good and super clean. I only have and issue with the batteries but I don't really know what happens. I charged but it seems to not be charged enough. But afterwards it worked well.

I love how clean my windows and mirrors look after one pass. My mirrors stay clean for so long, and the noise on the karsher isn't horrible I can deal with it!!
After you charged your cleaner (170 minutes) and filled the spray bottle with water and window cleaner concentrate, you can start cleaning. Spray the window with liquid and wipe it off. Water and dirt are sucked in thanks to the vacuum function. No liquids dripping on your windows and the windows are sparkling clean like never before. The cleaning solution doesn’t leave any streaks. It takes only a few minutes to clean a medium size window, and after having done all the windows in my place, the cleaner still had the most of its battery. It’s not too noisy, and does the job well making it fun. If you have some difficult stains, you can use a scraper that is detachable. There are two wipes - yellow and grey (more abrasive) for inside and outside accordingly. Most ...

There are two wipes - yellow and grey (more abrasive) for inside and outside accordingly. Most importantly, the cleaner is cordless which makes it so very convenient to use. It’s light enough and easy to assemble together. Also, you will never be caught by a surprise that the battery is over while you are cleaning because the running time is displayed on the display (initially 100 minutes). I can’t wait to try it on my bathroom tiles as they say it works on them too!
I used the product on my balcony doors, mirrors and windows and I truly recommend it! Quick and easy to use, you’ll get everything clean and sparkling in no time!!
It is a very powerful device. Easy to use, even a child can do it. Light, quiet and beautiful. I washed all the windows at home. If you have windows, you need this.
I was surprised to see that the spongy end doesn’t connect to the steam main part, you have to spray clean your surface and then use the main device. It leaves the windows and mirrors sparkling. It’s also possible to use it on other hard surfaces, which I find amazing. Also, you need to charge it first and then you can use it cordless so it’s super convenient.
Great for cleaning windows but also mirrors around the house, lightweight so not tiring at use Great use different microfiber towels included
I really loved the fact how easy and instructive the directions were for this cleaning gadget. It was effective in removing stains and super high quality. I would recommend it for sure.
