ABSTRACT:
A floor covering removal machine for removing a floor covering that is secured to a floor that includes a drive frame formed with an underside caster assembly, and feed, ejection, and oppositely arranged cutter sides. A variable speed, reversible, motorized drum is mounted about the frame and cooperates with a gripping idler roller that is releasably biased toward the drum to establish a grip interface which conveys the floor covering from the feed to the ejection sides. In operation, the floor covering is pulled through the grip interface and thereby removed from the floor. The machine also may include a collapsible guide handle extending from the drive frame and a motor speed control. Optional retractable floor covering cutters are included that are deployable in a floor contour-following configuration. An optional alignment laser pointer is mounted on the frame for alignment during operation.
