Robotic floor cleaners have been available as consumer products for a number of years now but with a gradual drop in production cost and development of new technology, these cleaners are becoming cheaper. In this teardown we will look at a Robotic Floor Cleaner which uses "electrostatic forces" to remove dust and can clean a room with its "intelligent" obstacle navigation.
