    摘要: By improving a structure of a discharge flow path of a robot cleaner, it may be possible to minimize a loss of a suction force, thereby reducing a noise without deteriorating cleaning efficiency. The robot cleaner includes a fan motor configured to generate a suction force, a first housing in which the fan motor is accommodated, a second housing in which the first housing is accommodated, and a chamber positioned between the first housing and the second housing, wherein a plurality of slits are formed in the chamber.
