I think one of the best recent products in Canada are vacuum cleaning robots. These robotic vacuum cleaners are like remote control cars that kids play with, but instead, they vaccum your house. There is a setting on some advanced vacuum robots that allows them to vacuum the house just by themselves, with no supervision. The better brands of vacuum cleaning robots have a timer and go aroudn the house, clean the floors, then return to their base and charge themselves. All you need to do to maintain such robotic vacuum cleaners is to change their bins every once in a while. who still thinks keeping your house clean is hard?
