A large area surface cleaning tool, for suctioning both dust and debris from a surface being cleaned, comprises a housing having a surface facing peripheral bottom edge defining a suctioning bottom opening. An elongate wand has an inlet disposed in suctioning relation with the suctioning bottom opening of the housing and connected in fluid communication via an airflow passageway to an outlet disposed exteriorly to the housing and in fluid communication and in debris transfer relation to a vacuum source. A first debris duct operatively mounted on one of the housing and the elongate wand for movement therewith and having a debris inlet disposed in suctioning relation exteriorly to the housing at least partially above the peripheral bottom edge of the housing to thereby accept debris too large to pass between the peripheral bottom edge and a surface being cleaned during use, and connected in fluid communication to a debris outlet disposed in debris transfer relation to the vacuum source.
