Using thick dirt-grabbing ridges and grooves, Swiffer mop leaves your floors cleaner than a broom does, even on textured surfaces. That's because it easily conforms to the surface of your floors and grout lines, picking up more dirt, dust and hair than a broom does. Swiffer Professional leaves no residue and is safe for use on wood floors, ceramic and vinyl tile, electronics, and other hard surfaces. Swiffer dust mop can be used with dry and wet cloths. Mop handle breaks down into four parts for storage and to adjust length. Swiffer Professional floor mop is recommended for use on wood floors by the wood floor experts at Armstrong.* *recommendation as part of a co-marketing agreement
