A robotic vacuum cleaner‎,‎ often called a robovac‎,‎ is an autonomous robotic vacuum cleaner that has intelligent programming and a limited vacuum cleaning system‎.‎ Some designs use spinning brushes to reach tight corners‎.‎ Others combine a number of cleaning features ‎(‎mopping‎,‎ UV sterilization‎,‎ etc‎.‎‎)‎ simultaneous to vacuuming‎,‎ thus rendering the machine into more than just a robot ‎"‎vacuum‎"‎ cleaner‎.‎
