Abstract
An auxiliary waste removal system for a surface maintenance machine, having a vacuum wand for removing waste from the floor surface, a reusable bagless waste collection container removably coupled to the vacuum wand, and a vacuum source fluidly coupled to the bagless waste collection container, the vacuum source generating a vacuum flow from an inlet of the vacuum wand to a vacuum outlet, the vacuum outlet being positioned downstream of the bagless waste collection container and the vacuum source such that the waste suctioned from the floor surface by the vacuum wand travels along the vacuum flow path and is directly received in the bagless waste collection container.
