  • Abstract: The DIY vacuum cleaner car we made runs smoothly and is perfect for daily dusting. It can easily suck up dust and small debris from the floor, such as cookie crumbs and pet hair. It is user-friendly, just turn on the switch and it can move on its own, avoid obstacles in its path, and even turn on a light in the dark to signal people to avoid stepping on it. This makes cleaning not only easier but also more interesting. The vacuum cleaner car can be our little helper in keeping the environment clean. Through this simple and practical invention, we learn how technology can support our daily activities and help with household chores. It’s an engaging and hands-on way to explore problem-solving, design and innovation while making a real difference at home.
