The Glider D-2, Magnetic Window Cleaner for Double Glazed Windows, with up to 20 mm Thickness by The Glider

マンションの3階で使っています。ベランダ以外にも窓がありますが、これのおかげで簡単に掃除ができるようのなりました。ジョンソンの泡スプレーを使っていますが、ペアガラスでも滑らかに動き落ちたりもしません。

So it sounded reasonable in principle . . . but there were some bad reviews. However, this thing actually works, with care and a little practice. Notes: the magnets are very attracted to each other - like teenagers in the first passion of youth - so treat them like a couple you know going through a divorce i.e. keep them well away from each other unless there's a pane of glass between them. Each left on its own then each is very attracted to any ferrous objects that's about - belt buckles (good way to carry ONE of them) etc. - they like to 'play away'. They lose attraction a little when the blue clothes are on for the second 'shining-up' stage, so at all times you need to keep the ring on your finger because you WILL lose the outside one several times. I forgot to put window cleaner both sides to begin with - makes the job much harder, but I'm used to me being stupid so no sweat. Gets into the corners well and I just used common sense and observation to chose the best wiping path. So not cheap but it got two windows cleaned on the outside that had NEVER been cleaned, and they DO do both sides at once . . . and they cost less than one visit from the window cleaner. So not cheap but definately value for money. Delivery was very quick - next day. Bit over-packed.

Supposed to work on windows up to 20mm thick. In apartment block with double glazing within the max of this range but no grip between the two magnets at all . Waste of money - would like to return as 1st attempt and you don’t know till you try live on windows

This product worked exactly as described. I found it didn't clean quite as well as I can with a paper towel on low windows, and I had to move a little slowly with it to maintain the magnets at all times, but it enabled me to clean windows that I haven't been able to clean in decades! The last time I was able to get a ladder in through my flower beds and shrubs and bring a pail of soapy water to scrub the bird poop off my upper windows was 20 years ago. With this tool I could clean the entire window, and scrub the dirtier spots (that won't come off with a hose alone). I did drop it a couple of times, but the handy ring and string did their job perfectly and I could reel it back in and reattach it, no problem. I will have clean windows on my upper floors again!

We live in an apartment and have some windows that are high up and not possible to clean on the outside as the only open a tiny amount for safety. They were filthy. I was skeptical but really hoped these magnetic window cleaners would work. And they did! Exactly as they were supposed to. We bought the blue one. The magnets are VERY strong and the squeegees glided well. The only trick is getting the cleaning solution sprayed on the inside and the outside of the window. Our windows open enough to get a hand around and managed to get a generous amount of windex spray on the outside. I am very happy with this product and was definitely worth the investment.
