New Delhi, Dec. 26 -- A clean floor sounds simple until you are the one living with it every day. I also have a slightly annoying habit of noticing everything, and once I see it, it starts feeling like a problem that needs fixing. My home is mostly tile and marble, with a couple of mats and one rug, so it is a mix of dry dust, hair, and the occasional kitchen spill situation.

Now here is the part that really gets to you. Do you ever feel like your maid cleaned the entire home an hour ago and somehow it is already messy again. You cooked food, chopped vegetables, and the kitchen is dirty again. Or you have a pet, they eat, and a few bits fall outside the bowl. There are so many chances when your home is clean but the rooms still get dirty...
