The Bona Hardwood Floor We Cleaning Pads are very thick and sturdy.  I have just pulled up carpet from my very old hard wood floors.  I thought I got all the staples up, but there are a few still left.  My previous cleaning pads would rip when I ran them across the staples.  The Bona pads have not ripped at all.  It's Winter right now, and the roads and sidewalks are covered with salt, which gets tracked in no matter how much you wipe your feet.  The floors are constantly a shade of gray.  My old cleaning pads weren't cleaning up the  snow salt from the floor very well.  Even after mopping, the floor was just streaked gray.  With Bona pads, the floors are streak-free and shiny.
