What's the point of washing your windows if you can't do both sides? That's a question highrise apartment dwellers have always found frustrating. Until now, that is: the Zatz model ZA-1 magnetic double-sided glass cleaner lets you clean both sides of any glass window - in only half the time and with no extra effort!
The ZA-1 features a clamshell design that incorporates magnets in each half. One part has a coiled telephone-style cord that the user attaches to their wrist, just in case the sponge comes loose and drops 10 or 20 stories. Don't you just hate when that happens?
Instructions are included on how to best use the Zatz ZA-1: to save the suspense, it seems a continuous serpentine motion is recommended. If used "properly", the outside sponge will stay firmly attached to its inside twin through the invisible attractive power of magnetism.
Stepping back just a bit, one can say that the Zatz ZA-1 is the latest in a long line of over-engineered Japanese consumer products that only work as they're intended when the situation is exactly right. If your windows are the non-opening kind, for example, you're out of luck because there's no way to get the magnetic sponge onto the window.
The Zatz ZA-1 also isn't the best at cleaning edges and corners. But maybe I'm being too picky... for 1,575 yen (about $17.50) at Tokyu Hands, one can't expect miracles. Is that clear? (via Impress Watch)
UPDATE: Similar Magnetic Window Washers are now available in the U.S. Take a look at this one and this one, both available on Amazon.
