The first great thing I noticed about these cloths is that they are easy to attach to the swiffer.  It has pinch type "holes" that you just push the cloth ends in to. There are no clasps you have to lift; the cloth doesn't even have to be pulled tight to work.  First, I tried using it on my kitchen floor. It easily picked up and held small crumbs. It gets close to the baseboards. I then went into my master bedroom. I was AMAZED by how well it worked on my wood floors. I typically move the dressers and sweep under them...this swiffer bends parallel to the ground and gets easily under furniture...as well as reach the center of under the bed! I just swept my room a few days ago, yet It picked up LOTS of loose hairs and dust! I would estimate one cloth works for one room's worth of sweeping.  I will definitely be purchasing more of these...less dustpan use for me! [This review was collected as part of a promotion.]
