Freelancer Tim Hornyak, author of "Loving the Machine: The Art and Science of Japanese Robots" has written a short review of Evolution Robotics' new Mint floor-cleaning robot over at cnet. Mint is a sweeper/mopper with a unique square-ish shape that improves treatment of corners. Its navigation system keeps track of where it's been so it doesn't miss any spots, and uses sensors to avoid rugs and stairs. Mint uses rectangular disposable cleaning cloths that are compatible with some Swiffer brand cleaning systems and widely available at stores.
