Hey, if you've got one of those Bona flat mops (you know, the spray mop kind) and the pad is getting worn out, this is a perfect replacement. It's a single, dark blue microfiber pad that measures about 18 inches by 6 inches, so it should fit right onto the mop head plate. The microfiber is super absorbent and great for grabbing dust, dirt, and grime without scratching your floors. You can use it for both wet mopping (just spray your cleaner first) and dry dusting. The corners are flexible to get along baseboards, and it's machine washable, so you can reuse it a ton of times – just toss it in the wash when it's dirty. To put it on, you just lay the mop head flat on top of the pad and press – the hook-and-loop material grabs it. To take it off, just peel it from a corner. It works on all kinds of hard floors: wood, tile, laminate, marble, you name it. Remember, this is just for the pad; the mop handle isn't included. A cheap and easy way to keep your mop working like new.
