A convertible blower port for a vacuum cleaner includes a cylindrical port wall carried by a portion of a vacuum cleaner. The port wall has a first end facing inwardly toward the vacuum cleaner and a second end opposite the first end. The port wall defines a blower passage in communication with the plenum of the vacuum cleaner. A blower port outlet is provided on the second end of the port wall. A removable cap closes off the blower port outlet and has an exterior surface for gripping the cap and has a hub configured to fill the blower passage. The hub has a substantially smooth inner end face that is positioned generally across the first end of the port wall and faces the plenum of the vacuum cleaner.
