A robotic vacuum cleaner, often called a robovac, is an autonomous roboticvacuum 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.
Robotic vacuums may be part of a more general purpose domestic robot. For example, some models integrate security cameras, intercom systems and other features. There can also be general caretaker service robots that have the ability to perform other basic housework tasks such as moving items, preparing food, and other cleaning in addition to vacuuming.[unreliable source?]
