1. An autonomous vacuum cleaner comprising:
a 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, the housing including a first side, a second side opposite the first side, and a front portion extending between the first side and the second side;
a suction nozzle proximate the front portion;
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; and
