Nick's Vacuuming

I sent Nick into clean his room, and he proceeded to tell me that he was done. So I told him he needed to vacuum his room too. And when he went into vacuum he vacuumed up this little toy..

And he burnt up the belt in my vacuum. Don't ask me how he didn't see the toy. It's not that small. So I ask myself do I let my children vacuum if I can't trust them not to vacuum up their toys.. Can I tell you that burnt rubber smells really bad, and our vacuum still smells of it. Hopefully the smell will go away soon.
