BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to a vacuum cleaner tool for use in a household, office or light industrial environment for cleaning carpets, floors, walls, and other vertical and horizontal surfaces, draperies, upholstery, etc. and, in particular, to a vacuum cleaner tool which has an opening therein and a swivel mechanism which enables the user to vacuum perpendicular surfaces without changing the orien- tation of the wand, hose or the like, which couples the tool to the vacuum cleaner. Further, the present invention is directed to a vacuum cleaner tool having an air-powered turbine motor for driving an agitator device, such as a brush, which extends from the housing and, in particular, to a vacuum cleaner tool having an agitator brush extending from the housing in which the housing has a removable wall portion which incorporates an air nozzle for the air turbine and which, when removed, allows access to the turbine and brush for the removal of large particles which may be obstructing the tool. 2. Description of the Prior Art The use of a vacuum cleaner tool to vacuum steps has been a problem in the past because the step contains two perpen- dicular surfaces, the horizontal tread portion and the vertical the separate compartment within the housing, and the pulley and drive belt compartment is sealed from the portion of the housing containing the turbine motor in order to prevent leaks and enhance the efficiency of the turbine motor. The agitator is enclosed within an agitator enclosure portion of the housing, and the housing further includes a removable wall portion which has an air nozzle positioned thereon. The air nozzle extends from the agitator enclosure portion to the turbine chamber of the turbine motor, and forms at least a portion of the peripheral wall of the turbine chamber. The nozzle directs air from the agitator enclosure into the turbine motor.
