Which for the floors?

Okay everyone, this is a big decision so I need your input as soon as possible.

I'm in the floor-cleaning stage of planning, and I need opinions on what kind of tool to clean the floor with. Right now the options are:

• A standard mop


• A swiffer mop


• A big sponge


• An old toothbrush


• My cat

Let me know what you think!
