A robot vacuum is an automated cleaning device designed to navigate and clean floors without human intervention. It uses sensors to detect obstacles and can move around furniture while vacuuming dust, dirt, and debris. Many models can be programmed to operate on a schedule, making it convenient for users to maintain clean floors regularly. Most robot vacuums are equipped with rechargeable batteries, allowing them to return to their charging stations when low on power. Some advanced models can connect to Wi-Fi, enabling users to control them via smartphone apps. They are popular for their efficiency and ability to save time on household chores.
