Most vacuum cleaners are reactive devices in that they clean the dirt off your floors after it falls off your shoes. I think the better approach would be a more proactive device that helps prevent that dirt from ever getting on your floors to begin with. That seems to be exactly what this crazy vacuum floor mat is meant for.
It looks like a format with little green up sticking off and those notes have vacuum suction power streaming through. When you step on the floor mat, the suction slurps the dirt right off the bottom of your shoes.
The floor mat was developed in Asia, the home of strange gadgets. The big downside to this cool vacuum powered floor mat is the cost of about $6000. This might be the perfect thing for homes with small kids and parents who are constantly vacuuming floors.
