Neato Robotics XV-11 Robotic Vacuum Cleaner: Effortlessly remove dirt, debris and pet hair from carpets and hardwood floors in your home using this robotic vacuum cleaner, which features a laser navigation system for automatic propulsion.
I've had it about a week and a half now. It's easy to set up and start. Its vacuum is also as powerful as my upright. The problems I've encountered are: - Its motor is powerful enough to move the dining room chairs and trap itself - It needs a homing device to find its recharging base after it has been moved - The curved edges on my sofa makes it work quite a while to get around them and then seems "confused" and goes right back into the same place after extricating itself - The magnetic barriers are sometimes ignored allowing it to go into areas in which it gets stuck - Finally, it sometimes shuts down in the middle of a room when it's done.
It needs some more work. Also, a "Return to Base" button on top would be nice.
