It's like a BOGO sale, but with intelligent, cleaning robots! All you have to do is purchase the Scooba for a blistering $400 and you can get the Roomba 401 for free, a $119 value. For those unaware, the Scooba is a robot that sloshes water on the floor and mop up your filthy messes and the Roomba is a vacuuming robot for hard floors or carpet. Both of which are pretty awesome, if I do say so myself.
P.S. If cleaning robots aren't your bag, the Woot-Off is still going on.
