Abstract: A robotic dust collector includes a suction member having a suction inlet and travels on a cleaning target surface. The robotic dust collector includes a guide member, a support part, and a biasing member. The guide member is disposed at the suction inlet and has a blade part facing the cleaning target surface. The support part supports the guide member in such a manner that allows the guide member to pivot about a pivot axis so as to allow the blade part to move in an up-down direction. The biasing member is configured to exert biasing force on at least a part of the blade part.
