Clearly he has the wrong one.
I've had a roomba for about three years now. The only problem with it was about six months ago when we finally had to replace the battery (and since the battery is listed as a consumable/perishable part that you should expect to replace at some point, two and a half years wasn't bad). We pair it with a handheld Dyson for doing the stairs, the car, and any other awkward places.

My typical cleaning session goes like this: chuck shoes and bags into the hallway, heave magazines, books, knitting, etc onto the sofa. Close doors. Set up virtual wall around my desk. Press button. Drink tea and read b3ta newsletter for 45 minutes. Feel smug and virtuous about having done housework.
