A series of robotics novelties were showcased at the annual Consumer Electronics Show "CES" this week in Las Vegas.
Among many others, Californian company Evolution Robotics introduced it's "Mint" floor cleaning robot, which can dust and mop hard surface floors - have a look at PhysOrg for some in-depth coverage.
More quietly a small Silicon Valley based startup called Neato Robotics has announced the official release of its XV-11 robotic vacuum cleaner robot (some good robotics coverage over at Automaton).
Both robots look to be designed to bite off a chunk of iRobot's market share - and both use SLAM to map rooms rather than iRobot's random walk strategy.
