My invention saves space, heavy for you to hold onto, and it keeps up with your dental hygiene. This invention is amazing because it has a lot of stuff into this invention that astronauts love, lots of awesome features. My design can be multi purposed, but the only bad thing is that it would cost more to have it updated. But you can put in a charger port for a flashlight, If you don't want to float just hook a harness to the tooth brush vacuum to keep you from floating around the space shuttle and bumping into any buttons. This is a great invention for astronauts to keep up with their dental hygiene . Each astronaut would have to get their own. My invention can also have a built in night light and a hand held flashlight.
