A large area surface cleaning tool comprises a housing defining a substantially hollow interior, and having a perimeter portion that terminates downwardly in a surface facing peripheral bottom edge that defines a suctioning bottom opening, and having a selectively movable portion for permitting access by debris to the interior of the housing, when, in use, at least a portion of the surface facing peripheral bottom edge is in contact with a surface. An elongate wand has an inlet end disposed in dust and debris suctioning relation with respect to the substantially hollow interior of the housing and is connected in fluid communication and in debris transfer relation via an internal airflow passageway to an opposite outlet end disposed exteriorly to the housing in fluid communication and in debris transfer relation with a vacuum source. The selectively movable portion is movable to permit access by debris to the interior of the housing to thereby permit access by debris through the elongate wand and into the vacuum source. Alternatively, an elevating means may be mounted on the housing for causing movement of the suction cleaning housing between a lower dust suctioning position and a raised debris suctioning position.
