Abstract

A portable floor scrubbing machine, which preferably is battery-powered, may operate in two distinct modes: either as a walk-behind floor scrubber or as a manually-operated, scrub-and-recover system using a floor wand having a cleaning solution dispenser and convertible brush/squeegee at the working end of the wand for use in locations with difficult access.
