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
a brush roll rotatably supported within the suction nozzle and configured to engage a surface to be cleaned,
wherein a length of the brush roll is less than a width of the front portion as measured between the first side and the second side, wherein the brush roll is laterally offset relative to the housing such that the brush roll is located closer to the first side than to the second side, and
further comprising a wall follow sensor disposed on the first side.
