Autonomous vacuum

An autonomous vacuum cleaner comprising:

• an outer housing with one or more of a controller, a sensor, and an automatic wheel assembly operable in combination to sense a surrounding environment and to navigate about the surrounding environment to perform a surface cleaning operation without continuous human input;
• a suction nozzle;
• 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,
• the suction motor and the fan assembly having an axis of rotation and a fan of the fan assembly rotatable about the axis of rotation, the debris separator including a cyclonic separator operable to separate debris from the airflow, the cyclonic separator located within the housing, the cyclonic separator including:
• a cylindrical wall along a longitudinal axis, the cylindrical wall having a first end and a second end and,
• 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.
