Abstract
A cleaning head for an air flow type cleaner defines an open-faced chamber for facing the surface to be cleaned. An air recirculating conduit draws air from the chamber through a first port in the chamber adjacent one end thereof. A baffle in the cleaning head is positioned substantially between the one end and the first port to reduce the flow of dirt-laden air to the one end. By this invention, one or more apertures provide communication at a central portion of the baffle substantially between the first port and that volume within the chamber which extends between the baffle and the one end, to provide air suction to prevent dirt accumulation in that volume.
