Trust me...I'm the Rug Doctor.

First of all, if you don't watch Doctor Who, then very little of this will make any damn sense to you, so you'll probably want to quit after the bit with the kittens, or else quickly go and watch a couple seasons of the series so that you can follow along. (You'll have to forgive the first episode, the one with the mannequins. Stick with it, I promise it gets better. And by better, I mean awesome.) If you don't have time for all that, but you still want to keep reading, you should at the very least read Neil Gaiman's (78-word) summary of not quite 50 years of backstory from the middle of this post.

Anyway, now that we're done with disclaimers, you either remember, or are about to learn that a little while ago, my wife and I fostered a pile of kittens. No, literally:

This is the part where you go "awwwww!" Also,
Gandalf isn't in this picture because he was busy
helping Hobbits get into places they shouldn't be,
or something. The rest, from top to bottom are
Loki, Alfredo, Rory, Guinevere (Gwen), and Eowyn.

They lived with us for about 6 weeks and demonstrated the effects of entropy on our second bedroom. Most of them also demonstrated, at one point or another, the effects of the various bodily functions of kittens on carpet, walls, floor lamps, desktops, and occasionally, litter boxes.

After all the kittens had found families, we brought home a cleaner that claimed to be a Rug Doctor, but which seemed a bit too aggressive to be telling the truth on that point. If it were really a Rug Doctor, it would have just talked to the stains until it convinced them to go back where they came from, or maybe used some kind of sonic attachment to loosen the stains from the carpet. If that had failed, it probably would have just run away until it thought of something really clever to do.

Trust me...I'm The Rug Doctor.

Of course, even after your carpet was clean, it would still keep popping back in at least every few months, insisting that you accompany it to some other beautiful-yet-dangerous faraway carpet in dire need of cleaning, until finally you were separated in a heart-wrenchingly tragic season finale.

This, however, is not actually a Rug Doctor. It's clearly meant to be a Rug Dalek–look at the shape. It's big and mechanical, and its main function seems to be to turn clean water into dirty water, which is exactly the sort of thing a you would expect a Dalek to do. Also, it doesn't do well going up stairs.

The Rug Dalek has no compassion or mercy, only hate. It will exterminate stains! Sure, it may also exterminate your carpet, furniture, house, pets, family, neighbors, and in all likelihood, entire planet, but by Davros, you'll never see those stains again–and not just because you've been blasted into oblivion by a death ray! (But yes, primarily because you've been blasted into oblivion by a death ray.)

And so will you, in all likelihood.
