Electrolux is already onto the second version of their Trilobite robotic vacuum cleaner, which with its retail price
of around around $1800 we're guessing is going to do a terrible job competing with iRobot's $200 Roomba Robovac. (The
only honorable way to settle this would be to have the two robots fight each other to the death). Anyway, besides being
able to recharge itself automatically (something the Roomba can't do), the Trilobite 2.0 has a few new features like it
can detect stairs and be programmed to clean at specific times.
