A robotic vacuum cleaner ;sometimes called a Robovac or a Roomba as a generic trademark, is an autonomous robotic vacuum cleaner that has a limited vacuum floor cleaning system combined with sensors and robotic drives with programmable controllers and cleaning routines. Early designs 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, and some include a number of cleaning features along with the vacuuming feature (mopping, UV sterilization, etc.). More recent models use artificial intelligence and deep learning for better mapping, object identification, and event-based cleaning.

Marketing materials for robotic vacuums frequently cite low noise, ease of use, and autonomous cleaning as the main advantages. The perception that these devices are set-and-forget solutions is widespread but not always correct. Robotic vacuums are usually smaller than traditional upright vacuums and weigh significantly less than even the lightest canister models. However, a downside to a robotic vacuum cleaner is that it takes an extended amount of time to vacuum an area due to its size. They are also relatively expensive, and replacement parts and batteries can contribute significantly to their operating cost.
