Sure, Roomba has that whole remote control vacuum going on, but Chinavasion (not Chinavision) has the G182, a robot vacuum cleaner with IP WiFi enabled camera.
Why would you want to do that? So you can go online and vacuum your house from a first-person point of view, of course. Granted, I wouldn’t want to do that, but its web-enabled IP camera has a microphone with a 360 degree pan and tilt IP camera design. Can the user program it to roam around the room and film things? Why else have a microphone on it?
So if you are at work, and you just learn that guests are coming over, you can just go online and suck up the dirt. Of course, I don’t see how you can turn on the vacuum from a distance, as it has a toggle switch right on it.
The G182 can detect walls via infrared technology, and it will go to the automatic charging area whenever it is low on power. On the product page, I see a remote control, but that must be from a shorter distance away.
You should be able to get the G182 on the Chinavasion website for about $500, but you can get it cheaper the more you buy.
