The iRobot Dirt Dog is a cleaning robot based on the Roomba platform which replaces the Roomba's vacuum cleaner with a series of brushes designed for cleaning up loose hardware and debris from workshop and garage floors. It is similar to a low-end Roomba, with a simplified user interface, and is compatible with accessories designed for iRobot's other domestic robots. The Dirt Dog lacks a vacuum motor, relying only on brushes for cleaning.
