Apparatus and methods for particulate containment and collection are disclosed. In one aspect of the invention, an apparatus includes a shroud attachable to the floor machine and having a skirt portion positionable proximate a work surface to define an at least partially enclosed chamber therebetween, an intake member attached to the shroud and positioned proximate the chamber, the intake member having an intake aperture positionable proximate the work surface and in fluid communication with the chamber; and a vacuum duct having a first end fluidly coupled to the intake member and a second end coupleable to a vacuum source. The containment chamber confines at least some of the particulates produced by the floor machine, thereby improving the effectiveness of the vacuum source. The shroud may be removably attachable to the floor machine. In a further aspect, the shroud may have an exhaust aperture disposed therethrough, the intake member having an engagement portion slideably engaged into the exhaust aperture to permit the intake aperture to be adjustably positionable proximate the work surface. In a further aspect, an apparatus includes a diffusion member disposed proximate the intake aperture and positionable proximate the work surface. The diffusion member creates a high-velocity airflow at or near the work surface, thereby improving the effectiveness of the vacuum source at removing the particulates from the work surface. In still another aspect, an apparatus further includes a floor machine having a treatment member engageable with a work surface. Alternately, an apparatus further includes a vacuum source.
