Honestly though, ever since I was a little kid, I've always thought of this little tank thing, that you can lower your blinds (the one that go up and down, not side to side), and it's like a fish tank.. Though, it brushes, rubs, and cleans all the dust off...
It's always been a pain, getting yelled at to clean my blinds.
Another thing, was to make a little pole, like a dolley, but have a magnet, and when you're in the workplace cleaning up, just use it like a vacuum cleaner, and just go over everything metal, like nails, so you don't pop any holes in your tires...
But somebody stole that from me.
