I bought these to use on my Swiffer WetJet because in the reviews someone specifically said they worked great on them. When I received them, I was a little disappointed because they were so big. It tells the size in the specifications, but I didn't measure and I was expecting something the size of the Swiffer. I started to cut it to size, but I hated to do it because they are stitched all the way around and I figured it would unravel if I trimmed that off. On the other hand, I use the mop in some pretty tight spaces and I figured having 2 inches sticking out on each side would make it clumsy. But I figured I'd use it like it was for a while, and found I love it just the way it is! Actually, I like it better... the sides flip up easily when you get close to a cabinet or baseboard and actually clean it better! Get this... you'll love it too!
