Claim 0:
1. A cleaner head comprising:
a case configured so that, when the cleaner head is positioned on a surface to-be-cleaned, a first edge region of a planar exterior side surface of the case is in contact with an upper surface of the case and a second edge region of the exterior side surface is adjacent to the surface to-be-cleaned, the case including
a nozzle connection portion, and
an air passage groove within the exterior side surface, recessed from a plane defined by the exterior side surface, extending from the first edge region to the second edge region, and having a width that is smaller at the second edge region than at the first edge region, so that, when a suction force through the cleaner head is generated with the cleaner head positioned on the surface to-be-cleaned, air flow along the air passage groove from the first edge region and then to the second edge region and then to the surface to-be-cleaned is generated so that foreign materials on the surface to-be-cleaned are drawn by the air flow; and
a brush rotatably disposed in an interior of the case and configured to rotate to move the drawn foreign materials from the surface to-be-cleaned into the case, to thereafter be provided to the nozzle connection portion,
wherein the case is configured so that, while the cleaner head is positioned on the surface to-be-cleaned and the exterior side surface makes contact with a wall surface, a passage enclosed by the air passage groove and the wall surface is formed.
