Mop bucket bag insert

An insert is provided for a mop bucket application to capture dirty water and/or clean water during floor mopping. The insert can be made of flexible PVC vinyl or of a similar substance giving the user the ability to quickly install the insert into a mop bucket. When the insert has collected the dirty water, the wringer can be quickly removed. Since the insert's bottom is flat, it will remain upright even when unsupported. The insert and contained dirty water can easily be removed by lifting the handles on the insert's two sides. The slick inside surface of the insert enables the dirty water to be poured with ease in a direct, substantially v-shaped stream. The structure of the insert preferably includes a body section which is connected at its two ends. A bottom portion forms a base for the body section, and side handles are affixed to the upper edge of the body section. A handle is secured to the outer side of the bottom portion.
