Abstract
A floor care appliance such as a vacuum cleaner is provided having a traction wheel powered edge cleaner comprised of a vertical axis rotary agitator which is affixed to either the right or left side of the suction nozzle. The agitator is rotated by the traction wheel when the vacuum cleaner is disposed along a wall surface and moved relative to the wall surface. The rotating action of the agitator sweeps dirt particles off of the wall surface and along the edge of the wall surface into the path of the suction nozzle for pickup. When not in use the edge cleaner is stored in the accessory storage rack like other accessory tools. The agitator can have differing agitator elements such as bristles or a fluff wheel.
