A floor cleaning device includes a base portion for movement along a surface. The base portion further includes a suction nozzle and a brush assembly driven by a brush motor for agitating the surface. The brush assembly includes a lifting mechanism for moving the brush assembly from a first position wherein the brush is off the surface to a second position wherein the brush assembly is on the surface. A switching assembly is responsive to the brush lifting mechanism to energize the brush motor when the brush assembly is in the second position.
