These 3M sweep and dust sheets reduce the risk of bad impressions by trapping up to 8X more dirt, dust and sand than when using traditional dust mops or a competitive sweeping dust cloth brand. They are simply a more efficient way to pick up dust and dirt, and convenient disposable sheets mean no laundering. Used under any flat floor tool or high duster, these sheets glide through and traps debris, even on wet floors. Take as little or as much as needed. They come in rolls perforated every 6" (152.4 mm) and you can use both sides.
