A:Answer It will not stand on its own fully extended. You have to push the button that makes it fold in half. Then push top half of unit forward to locking position. It will be half as tall as it was when folded over. Only then, will it stand on its own. Also the same button is used to bend the unit, to make it flexible, so it will get under furniture and tables so you do not have to bend over. Then push back into locking position for full length
