Automatic cleaning refers to the use of machines or devices that perform cleaning tasks without the need for human intervention. Common examples include robotic vacuum cleaners that navigate through homes, picking up dirt and debris while avoiding obstacles. These devices often use sensors and programmed routines to efficiently clean various surfaces. Another aspect of automatic cleaning is found in self-cleaning ovens, which utilize high temperatures to burn off food residues, making the cleaning process easier for users. These technologies aim to save time and effort, allowing people to maintain cleanliness in their environments with minimal manual work.
