Summary: I was a long time hold out for a Roomba. My wife wanted one, but I couldn't really see spending this much money to replace a chore that takes 10 minutes. Then it went on a heavy sale for Cyber Monday, and I gave in. I'm happy I did!
Summary: Works OK, wish the iRobot came with more, they don't give you enough of these when you buy the expensive robot so you have to come buy more of these lighthouses. They don't always work, sometimes the robot keeps rolling by.
