Abstract

A floor scrubbing apparatus that is particularly well suited to scrubbing carpet materials is disclosed. The floor scrubbing apparatus is manually operated and includes a drive roller coupled to a scrub roller. In one embodiment, the drive roller is coupled to the scrub roller using a gear arrangement that causes the scrub roller to rotate faster than the drive roller. If desired, the apparatus can include a cleaning fluid dispensing system. For instance, the apparatus can include one or more nozzles that dispense a cleaning fluid onto a carpet material as the material is being cleaned.
