Abstract
An autonomous vacuum cleaner includes an outer housing, a suction nozzle, and a suction motor and a fan assembly operable to generate an airflow through the vacuum cleaner from the suction nozzle through a debris separator to a clean air exhaust. A fan of the fan assembly is rotatable about an axis of rotation of the suction motor and the fan assembly. The debris separator includes a cyclonic separator operable to separate debris from the airflow, the cyclonic separator located within the housing and includes a cylindrical wall along a longitudinal axis and having a first end and a second end, a dirty air inlet, a clean air outlet, a debris outlet adjacent the second end of the cylindrical wall, and a dust bin in fluid communication with the debris outlet of the cyclonic separator, where the cyclonic separator is coaxial with the motor and fan assembly.
