Advice Please!

We have hardwood floors throughout most of our house. I like to keep them clean. I vacuum all the time and then once in a while, I steam the floors. That's been working for the most part. Except, how do you clean under the king sized bed?? I just can't reach that strip in the middle underneath the bed and the dust bunnies are taunting me. Feel free to share any tricks that I don't know!!
