"I have it on good authority that they're going to strap abrasive pads to a cat and push it through using a really long flexible pole."
Having attempted to use a cat for cleaning purposes before, I can attest that it is not the best idea in the world (no matter how fun it sounds!)
Although, I did have a cat who enjoyed being pushed around at the end of a mop, until I soaked the end of it and he got drenched. He didn't like it anymore after that, or me...
