The invention discloses a floor sweeping robot with self power generation and reminding functions. The floor sweeping robot comprises a floor sweeping robot main body, wherein the floor sweeping robotmain body is internally provided with a piezoelectric power generation structure; the piezoelectric power generation structure is used for converting mechanical energy into electric energy; the piezoelectric power generation structure is electrically connected with a storage battery; the storage battery is electrically connected with a buzzer. The floor sweeping robot has the beneficial effects that vibration caused when the floor sweeping robot is operated can be converted into electric energy which can be stored and reasonably used, and then the energy can be saved; due to adoption of the buzzer, the position of the floor sweeping robot can be reported, and a user can be helped to conveniently find the floor sweeping robot.
