What Is A Robotic Vacuum?
A robotic vacuum cleaner, often called a robovac, is an autonomous robotic vacuum cleaner that has intelligent programming and a limited vacuum cleaning system. The original design included manual operation via remote control and a “self-drive” mode which allowed the machine to clean autonomously without human control. Some designs use spinning brushes to reach tight corners. Others combine a number of cleaning features (mopping, UV sterilization, etc.) simultaneous to vacuuming. – Wikipedia
