Abstract: A removable and replaceable filter and filter holder is mounted within a mop cleaning bucket to receive dirt settling under gravity from the contained liquid with the dirt collecting in, and passing through so as to be trapped below, the filter and its holder. The holder is a rigid or substantially rigid perforated support structure spaced above and below the dirt receiving filter. In one embodiment, the holder is supported in the bucket in spaced relationship to the bottom of the bucket and protects the filter. The filter is a thin, sturdy, semi-rigid and floatable member with many holes so soiled water passes through and collects in the bottom of the bucket. The construction of the filter can be selected depending upon the material (grease sludge, dirt, oil, soot, or food particles) to be mopped up. The combination of the filter and filter holder blocks or dampens turbulence and prevents sediment from being stirred up in the bottom portion of the bucket.
