1. A vacuum cleaner suction head comprising: a housing having a lower surface configured to face a surface to be cleaned, a fore-aft direction, and a transverse direction that is perpendicular to the fore-aft direction; one or more supports connected to the housing to support the housing for movement in the fore-aft direction on the surface to be cleaned; a suction inlet extending through the lower surface of the housing, the suction inlet having a front edge and a rear edge located behind the front edge in relation to the fore-aft direction; a first plate pivotally mounted at the lower surface of the housing to rotate about a first pivot axis extending in the transverse direction, the first plate being movable relative to the housing between a raised first plate position in which a lower surface of the first plate is relatively close to the housing, and a lowered first plate position in which the lower surface of the first plate is relatively far from the housing; and wherein the first plate is mounted in a trailing configuration in which the first pivot axis is in front of the first plate with respect to the fore-aft direction and a lowermost point on the lower surface of the first plate is located behind the first pivot axis with respect to the fore-aft direction.
