Vacuum cleaner having a secondary dirt and dust collection inlet |
摘要 |
A vacuum cleaner includes a body having a container which collects dirt and dust. A surface cleaning head defining a primary dirt and dust collection inlet is configured to contact a surface over which the surface cleaning head is moved. A passageway connects the primary inlet to the container. A secondary dirt and dust collection inlet is remote from the primary inlet and spaced from the surface. The cleaner suctions dirt and dust through the primary and secondary inlets into the container. The primary inlet is adapted to draw surface-borne dirt and dust efficiently into the container and the secondary inlet is adapted to draw airborne dirt and dust efficiently into the container. Dampening means are provided to at least one of the primary inlet and the secondary inlet and is controlled by an actuator activated directly or indirectly by an operator of the vacuum cleaner.
