A robot vacuum cleaner is an automated device designed to clean floors without human intervention. It uses sensors to navigate around furniture and obstacles, allowing it to efficiently cover various surfaces like carpets and hardwood. Most models can be programmed to operate on a schedule, making it convenient for users. These vacuums typically feature a rechargeable battery, enabling them to return to their charging station when low on power. Many robot vacuum cleaners also come with smart technology, allowing users to control them via a smartphone app or voice commands through devices like Amazon Alexa or Google Assistant.
