is a robotic vacuum cleaner
However, in stark contrast to most other robotic vacuum cleaners, no vacuum cleaner mechanism is present, nor are there any circuits to decide on which path the robot takes. Instead a kind of swiffer cloth is attached to the bottom of the robot and this pushes the dirt along. The robot changes direction because the central wheel has a differential and thus drives into the direction with the least resistance. The Robosweep is NOT a Robomaxx, the Robomaxx is a real robot vacuum.
