Tyroler Magnetic Window Cleaner Tool | The Glider D-3 AFC Double Sided Outside Window Cleaner Fits Windows 0.1"-1.1" Thick, Adjustable Control Magnet Window Cleaner Tool, Ideal Magnetic Glass Cleaner

I live on a high floor of an apartment building, and our windows never get professionally cleaned. After years of buildup, they were extremely dirty. I’m so glad I found this gadget — it’s a fraction of the cost of hiring window washers and works surprisingly well.The magnets are very strong, so handle with care. That said, there's still a chance they can separate while in use, so definitely use the included safety string to avoid losing the exterior piece.

My directions were all in inches but the measuring tool was metric but just had to do some conversion. My windows are 9/16" thick. I have windows that are old and because of compression from my log home are impossible to remove from the frames. Additionally, the screens are impossible to remove also. Anyway, I was able to us lots of window spray on both the inside of the window and outside. You must keep both sides wet in order to side the device to clean. After getting everything wet and the scrubber in place between the window and screen, it was a little bit of a learning curve to scrub all the dirty and scale off the window. I had the magnets at their strongest setting and they would occasionally fall off if I wasn't careful. The string helps to recovery the outside cleaner but also has to be kept from getting caught and pulling the outside cleaner off the inside magnet. I wish the cleaner had an offset at one end so that I could slide it next to the locks but be behind them on the outside. I'd say the windows were about 95% clean when I was done and cleaner than they have been since I bought the house over seven years ago.

Will not stay on, windows only 12mm, on closest setting still won’t stay on window.You can tell instantly this is garbage. They didn’t even clean up the excess plastic from the mould. Children’s toys are far superior quality to this $90 piece of garbage.Returning.

I live on the third floor of an apartment building in which the upper pane of each window is fixed and about 30 inches square. I didn't think before I purchased the item that I wouldn't be able to get the gizmo onto the upper pane. So far, I can only clean the lower pane. I'll have to put my thinking cap and ask around on how to get the apparatus to the upper pane (if anyone from Tyroler is reading this and has an idea how to accomplish this, please let me know). Otherwise, the gizmo is well built, well thought out and will do the job once you practice. With any "alternative mousetrap" product like this, knowing what the purchaser may be up against in solving his or her problem, I would expect that the company would be helpful with ideas on how to overcome those problems. Had they done so through videos or how-tos on on the web site, I'd be much more enthusiastic about it. A squeegee on a long stick would have been much cheaper and effective.

Update - the seller contacted me and offered a free replacement with some strongest magnetic knobs. I really appreciated their effort, so I am giving them a five star review for customer satisfaction. After receiving the product, and still under the COVID 19 shelter-in-place order, I decided to give the green knob version a try. These green knobs definitely worked better than the blue knobs version I bought. The outside piece would follow the inside piece and not dropping.I started a self training session by cleaning a deck patio window I have access on both sides, and followed the instructions to spray windex liberally on both sides of the window, then, I used the rubber piece only, the tool cleaned well, all corner pieces would need a second try but all worked fine.The challenge came to clean my 15 ft tall windows which is on a 60 ft tall exterior wall. So the inside is accessible by ladder to 15 ft, and outside would have no ladder access at all because it was too tall. Therefore, I had no way to spray windex on the exterior, if I could, I probably just used my regular window squeegee. These windows came with a small opening at the bottom so I would use this landing area to launch the Green Knob Gliders. I had to use the microfiber towels came with the unit, soaked them wet and started the cleaning job. It was a slow and tedious process because if your windows were dirty like mine, these microfiber towels got dirty easily, I had to retrieve them several times, wash them, re-spray windex on them, and re-launch the glider. After the 4th run, the windows exterior start to show some shining cleanness. Though no magic, just hard labor, all worked, now I can slowly working on rest of the tall windows. BTW, the safety string came with the unit was too short, so I extend it.-------Following were for the blue knob glider review--------------------------------------------I bought this thing with high hopes, after watching the seller videos many time. I assumed I mastered the skills by practicing. In reality this device falls off easily when you try to clean at a minimal speed, if I clean very slow it does not fall but leaves soap marks. Now my cleaned window looked 10 times worse than before. I bought the D2 version for my double pane 0.5 inch glass window.
