Yes I could do with a robot mop-and-vac combo, but do I really really need need one? Or do I?

Saw a robo mop and vac combo on slickdeals for not that much and gave a serious thought about buying it. Like the only mopping my place gets is the steaming that I do maybe once every three weeks on a good month, and the vacuums are so often, the automated ones, when I'm fully settled into my place. But then, there's really not much surface area in the apartment to be mopped with water and without a child, pet or other human beings to clean up after, the floor stays on the cleaner side more or less. No real need for a complicated device that wouldn't half half its features used.

Or mayyybe if I get it, I'll design my furnishings around getting the whole place mopped? Hmmmm.
