Well. There is a similar CNN news report from August 28th, 2009... But that doesn't explain it. So, yes. It is a true trick. Here's a written news report about the same story a day before the video. And another.
The comments on this page discuss the story.
This guy answers the question generally, not relating to the story.
And, here's a forum site that discusses it and answers it.
So pretty much... It's fake. Nothing to do with the planets. These closed minded people contacted the news for publicity and insisted it was something holy. It's just a physics trick. I'm not gonna get a physician to explain it, but you can do it with most brooms. My personal explanation is that the bristles are in mass amounts putting a surface area on the floor that makes it practically a solid surface on the bottom, as if the bristles were covered with a block of plastic. Hard to explain, but since there are so many bristles on the bottom of a broom, it acts as a solid surface. At least what I think.
Have fun.
