Robo vac... I thought wtf do I want with a stupid little vacuum w/ poor suction and a small bin. I was wrong, it cleans OK, but it cleans 2x a day all on its own. And while i have a normal vac, I'm always too busy/lazy to get it out, so I would only drag it out when the place was visibly dirty; now it's always tidy (bcos I don't want the vac getting stuck) and clean.
Doing its thing...
