If you need to mop a large floor to just remove dust, then consider the Casabella Spin Mop. There are many spin mops on the market but this one not only spin dries the mop to remove excess water before each mopping, it also spin rinses the mop to remove dirt.

If, on the other hand, you need to mop a small area that has stuck-on dirt, like in a kitchen or bathroom, then the Bissel Steam Clean mop would do you well. The steam from the mop will melt dirt so it can be mopped away.
