I was so excited when first got a roomba 5 or 6 years ago, but that faded so fast after it turned into an endless stream of notifications that it was caught under furniture, stuck on a cliff (the edge of a rug), full of dirt, couldn't find its base, or trapped under a maze of dining room table legs.
I love the idea, but man that was $500 wasted. I'm sure they are better now, but I cant bring myself to buy another one.
