Robot vacuum cleaners are automated devices designed to clean floors without human intervention. They use sensors and cameras to navigate around furniture and obstacles, allowing them to efficiently cover various surfaces like carpets and hardwood. Most models can be programmed to clean on a schedule and return to their charging stations when their batteries are low. These vacuums typically feature rotating brushes and suction mechanisms to pick up dirt, dust, and pet hair. Many robot vacuum cleaners also come with smart technology, enabling users to control them via smartphone apps or voice commands through smart home systems.
