Here is and example of one of those things, the Swiffer Duster. This thing is great! It has a telescoping handle, which means I no longer have to pull out the ladder to dust the ceiling fans the crown molding or the top of the fridge. Also it is great for dusting the blinds on the window.
Also they are disposable, trap the dust, throw in the trash. I have even found them in the Amazon.com subscribe and save department for cheaper than I can get them at Wally World and they are delivered to my doorstep, so it is a win/win.
Do you have any housecleaning tips or gadgets that you just couldn't live without?
