I have always been a hands and knees floor scrubber. This is how my mom did it, you can get the edges and corners good and really see the floor so nothing is missed. Well, I have entered the world of big belliness and to get down and scrub a floor and back up is just something I do not want to tackle right now. So, I bought a mop. It does a good enough job and it will be doing the job for now and probably for awhile. Soon all of my chores will be done with 2 babies strapped on so mopping will continue to be easier for quite awhile. I do wonder "what is left behind" but am not going to let myself think about that too much.
