The front and rear sealing plates extend along the front and rear edges of the suction inlet, respectively. the sealing plates are movable between raised positions in which the lower surfaces of the plates are close to the housing, and lowered positions in which the lower surfaces of the plates are remote from the housing. The front and rear plates are movable from the lowered position to the raised position by contact with debris on the surface to be cleaned.
