Roomba's a technological oddities. Sure, it takes a somewhat mundane chore and makes it effortless, but that's only in an ideal area. They always show you the video of this little vacuum easily cleaning an empty room, but when you toss furniture into the equation, it gets mildly annoying.

My sister was an early adopter of the Roomba because she lived alone, traveled a ton, and hated cleaning her hardwoods on her few days off. It seemed like a perfect fit. But occasionally, she'd wake up to find her Roomba wedge under the leading edge of the couch. That wouldn't be a bad thing if it didn't keep running trying to free itself, in the process leaving marks and scratches on some truly beautiful floors.

While her workaround was to take one of those free internet printout books (yellowpages) to block off that little passage, I can't help but think this would have been a stellar fix. Not so much a vacuum that screamed when it bumped into things, though hilarious, it be better if it called out for help when it needed assistance. Brilliant!

All the same, I would totally buy a Roomba that shouted angry words when it bumped into things just for the sheer hilarity of it.
