SURFACE CLEANING APPARATUS

A surface cleaning apparatus includes a housing that supports a motor which rotates a fan about an axle axis and a dirt collection chamber having an elongate axis about which the dirt-laden air rotates. The dirt collection chamber receives dirt-laden air from the passage in response to rotation of the fan. The dirt collection chamber axis is spaced from the axle axis and includes an openable door that permits a user to empty dirt from the dirt collection chamber while the dirt collection chamber is supported on the housing. A battery that operates the suction source includes a plurality of battery cells, has an elongate battery axis that extends through a majority of the battery cells. While the passage axis extends horizontally, both the axle axis and the dirt collection chamber axis are positioned above the elongate axis and the battery axis is positioned below the passage axis.
