I saw a review for one in WSJ just the other day (don't have a link, sorry). They made a good analogy which I will have to paraphrase from memory.

The robot vacuum cleaner technology is a lot like a dancing dog, in that you are spending so much time being amazed that the dog can dance at all that you fail to notice what a horrible job it does of it.

Never used one personally but that quote stuck out in my mind.

If true, consider that nothing else in the house that might dance is willing to, so even poor dancing is an improvement
