Abstract: The present invention provides a dust suction and charging device for a floor sweeping robot and a dust suction and charging method thereof. The floor sweeping robot has a floor sweeping robot body with a dust box arranged on one side of the body. A dust-box discharge port is formed on the dust box and corresponds to a maintenance-station dust suction port. The maintenance-station dust suction port can be communicated with the dust-box discharge port by pressing an outer surface of the maintenance-station dust suction port. Advantages: (1) the charging, dust removal and maintenance operations on the floor sweeping robot are realized simultaneously; and, (2) dust in the dust box of the floor sweeping robot is sucked into a dust bag of the maintenance station by vacuum, so it is unnecessary to take out the dust box. Therefore, it is convenient to clean and will not pollute the external environment.
