I was just surfing the glorious 'net today to see if we're far enough into the future for someone to have developed a self-cleaning house and check it out!!! Weirdly enough, it's been around a while...

A press of a button sprays jets of soapy water over the entire room, another button sprays clean water to rinse out the soap, and a third starts a giant fan that thoroughly dries the area. The walls, ceilings and floors are all covered with a water-proof resin, as is the furniture. The floors are slanted to allow the water to run off into a complex drainage system; any water that doesn't drain off the floor is dried up by the fan.

Valuables and vulnerable items are kept under glass, and of course there are no dust-collecting carpets. The kitchen cabinets double as a dishwasher - you simply place the dishes in the cupboard, close the door, and hit a button. After washing the dishes a fan dries them, so when you need a clean plate you simply open the cupboard and get one. The clothes closet acts as a washing machine and drier - you simply hang them up and leave them alone.

It reminds me of that episode of Home Improvement where Tim turns the whole kitchen into a dishwasher...

Unfortunately, judging by this photo, someone needs to invent a self-manicuring lawn to go with it.
