In 2006, "Popular Science" magazine offered an article that claimed we wouldn't have to clean our homes anymore by 2011. That was upbeat, and sadly it wasn't prophetic. We still have to clean our homes often. But the piece brought up some good points and was at least prophetic in-part. With lots of nanotechnology-based products on the market today, we will spend a ton less time cleaning our houses, our attire and our cars.
Much of this technology is founded on titanium dioxide. When exposed to the ultraviolet rays of sunlight, it reacts in a fashion that breaks down dirt molecularly and basically zaps it away. It involves the use of the light in a similar way that plants use it in photosynthesis. While green, growing things use sunlight to turn carbon-dioxide into oxygen, titanium dioxide uses daylight to turn bacteria into hydrogen, CO2 and other elements that are broken up into the air rather than remaining on the surface.
In addition to its property of breaking down dirt using daylight, titanium dioxide also reacts with water. Water beads on its surface, rolling off and collecting any dirt and dust with it as it rolls. This is also called the lotus-effect, named after the leaves of the lotus plant. The beading on the surface of the leaf causes the water to roll off, fundamentally cleaning the trail they follow as they are going.
The gigantic advantages of titanium dioxide used as a coating and built into surfaces is that dirt won't build up routinely thanks to the photosynthesis-like action, and when it does, it's going to be washed away because of the water-beading properties found in several common products like car polish. Some landmark buildings around the world have been sprayed with this sort of nanotechnology to keep their facades cleaner and to reduce the results of time.
The usage of this inside poses an issue at the moment, because of the need for sunlight. But research is generally moving the process forward.

We may not yet have homes that clean themselves like the story in "Popular Science" anticipated, but we can have just about self-cleaning cars thanks to the nanotechnology used in CeNano.net's Nanotol car polish.
