Automation is cheaper if you buy Chinese machines. I got a robotic vacum cleaner for 350 yuan (70 SGD) running around the house by itself with selfrecharge that sweep and mop the floor.

The dish washer cost only 100SGD and do not need special plates. It even has a self cleaning function. My solar system cost me 350SGD that provide constant hot water and aircondition at near to nothing in utility bill. My hydroponics grow chilly, curry leaves, kang kong, small Kalang in my backyard that cost nothing.
