This year, the Singapore Straits Times announced that already 10% of the Singapore population (4.5 million) are keeping robots at home to help with their chores. That's a big number. There are currently 3 robot types for sale in Singapore.

Robot Cleaner: Small, agile, intelligent. Uses a sensor at front of head to clean dust off the floor and pick up thrash.
Cost: S$2300 (Singapore dollars)

Robot Clothing Dryer: Dries clothing after washing. Hang on robot arms and the robot will dry it.
Cost: S$3500

Robot Vacuum: Hold the handle and the robot will guide you to areas where there is dust or dirt or thrash so that you can vacuum them up.
Cost: S$2780

I've discussed with my family on buying the Robot Cleaner it looks really cool!
