The Scooba did seem like a little more work, but then again it's a lot less of a mess than a mop and bucket.

I think the appeal of the Scooba is that when compared to what it's replacing (a person mopping), I think it would do a superior job. That's compared to the general idea of a Roomba, which technically does an inferior job at what it does compared to what it's replacing (a standard vacuum).

Anyway, I may also wait until their next version of the product, but having seen what you have to do to run one, I think I'd prefer it to the alternative

*edit*
I have to add, the Roomba is a fiancee-approved gadget. I get the nifty gadget that lets me do less house work, and she gets the knowledge that it will be in our shared home some day, cleaning our floors instead of one of us doing it
