A workstation on wheels comprising a housing having a shelf dividing the housing interior into an upper and lower chamber. The shelf supports a vacuum unit that draws air from the lower chamber and exhausts it into the upper chamber. The lower chamber is provided with a vacuum outlet to which is connected an inelastic ductwork. The ductwork includes a nozzle for receiving air and solid materials from a floor surface. The air and solid materials flow through the ductwork and into a bag or bin in the lower chamber where the solid materials are accumulated. The ductwork is rotatable about the vacuum inlet and may be a one-piece L-shaped structure. Alternatively, it may be longitudinally adjustable by multiple interconnecting duct parts or by telescoping segments. The ductwork includes an housing duct to which is connected a valved flexible conduit for providing an auxiliary vacuum source.
